obots are no longer something that belong in the future, sci-fi movies or comic books – they are here today transforming businesses, making industry more efficient and even working alongside humans.

Many companies will utilize automation more to grow their businesses in 2020, increase productivity and overcome challenges. Hector Villarreal, President of Weldcoa, told gasworld recently, “In my budgeting for 2020, I’m looking at automation to load the robots and the lasers because I can’t find people to work my second shift. I’m buying robots, to run my robots. How insane is that?”

Identifying the right product, and what jobs to use it for, is key and, for some, it is also about overcoming a nervous reluctance to adopt the technology.

We focus on automation this month and look at the potential it has for your business, and take a close look at new cobots on the market as more of you adopt or sell automation.

“Companies are automating everything,” a President of a leading US industrial gas distributor told me recently, and it is one solution to the skilled labor shortage in the US. But is there a conflict between these progressive initiatives and skilled welding jobs threatened by changing technology?

One recent example was the news the Port of Los Angeles shipping terminal is planning to replace diesel trucks and human workers with robots. To be competitive, companies

have to move towards automation as it lowers operating costs, boosts efficiency and solves labor shortage with the press of a button. But then what jobs will be left for humans to do? Find out how cobots can help businesses with a shortage of labor and an ageing workforce, and why it might not necessarily be bad news for welding jobs from page 20.

As well as utilizing the latest technology like automation, it pays to have a good website as more and more people choose to buy goods online as opposed to walking into a bricks and mortar store. Indiana Oxygen Company (IOC) is a trailblazer among the industrial gas and welding supplies community when it comes to e-commerce. IOC might be North America’s oldest industrial gas distributor, but it has moved with the times and its online store weldingsuppliesfromioc.com was recently ranked No. 5 in the category of “DIY, Tools, Supplies,” above any other welding supply only store, by weekly magazine Newsweek. IOC tells us how they got it right with its online welding supplies site from page 24.

We also have some great advice from ESAB on controlling gas surge, RoboVent provides tips on weld fume mitigation for tank manufacturers, GCE gives us some insight on oxyfuel cutting and Linde Gases explains the value of adopting additive manufacturing. Please keep us updated with your news in 2020, and get in touch with anything you would like to see featured in gasworld US. Happy new year!

Air Liquide: +2.0% for Gas and Services in Americas

Air Liquide reported group revenue of €5.5bn (approximately $6,095bn), up 3.5% on a comparable basis, in its 2019 third quarter (Q3) results.

The French industrial gas giant, which has US headquarters in Houston, said its Gas and Services posted sales growth up 3.5% in spite of a softening economic environment.

Gas and Services revenue in the Americas amounted to €2,137m (approximately $2,37m), an increase of +2.0%

during the third quarter of 2019. In Engineering and Construction, sales to third-party customers were stable compared with the second quarter, with resources mainly attributed to internal Large Industries and Electronics projects.

Within its Large Industries business, Air Liquide highlighted the signature of three long-term contracts in Q3, in the US Gulf Coast with Methanex, in Canada with Shell Chemicals and in the Philippines with Pilipinas

Shell. Large Industries sales were up +0.6%, affected by customer maintenance turnarounds in the US. Industrial Merchant revenue posted resilient growth of +1.1%, mainly driven by higher pricing.

Electronics growth stood at +1.5% and Healthcare continued to improve markedly (+11.1%).

Commenting on the Q3 results of 2019, Benoît Potier, Chairman and CEO of Air Liquide, said, “Sales growth continued this quarter, with Group revenue amounting to €5.5bn, up 3.5%. Growth was driven by all Gas and Services activities, which represent 96% of the Group’s sales, as well as our Global Markets and Technologies business. Positive currency and significant scope impacts offset lower energy prices.”

Potier continued, “All Gas and Services activities grew on a comparable basis, despite a more moderate

global growth. Healthcare and Electronics were particularly dynamic, and Industrial Merchant and Large Industries remained solid. Assuming a comparable environment, Air Liquide is confident in its ability to deliver net profit growth in 2019, at constant exchange rates.”

In a softening economic environment, growth in Industrial Merchant stood at +2.4%, driven mainly by successful pricing management, growth in consumer-related markets and a favorable number of working days. Sales growth was high in Healthcare, in particular in Home Healthcare in Europe and in Latin America, and in Medical Gases in the US.

Qatar to raise LNG production, helium potential

State-owned Qatar Petroleum will raise Qatar’s liquefied natural gas (LNG) production capacity to 126 million tons per annum (mtpa) by 2027, an increase of 64% from the current 77 mtpa.

Saad Sherida Al-Kaabi, the Minister of State for Energy Affairs, the President and

CEO of Qatar Petroleum, also announced that new studies have revealed that the North Field’s productive layers extend well into Qatari land in Ras Laffan, paving the way for a new LNG production project in the north of Qatar.

Minister Al-Kaabi confirmed gas reserves of

the North Field exceed 1760 trillion cubic feet, in addition to more than 70 billion barrels of condensates, and massive quantities of LPG, ethane, and helium.

Qatar’s expansion plans, with four new production facilities, known as LNG trains, is potentially a boost for future worldwide helium supplies which would help ease the current shortage, and is potentially a new Qatar 4.

“During the past two years, Qatar Petroleum worked diligently to determine the degree to which the North Field extends towards the south west, as well as the possibility of production from Qatar’s northern coastal

onshore areas,” Minister AlKaabi said. “I am pleased to announce that our appraisal efforts have borne fruit, and that we have confirmation that the productive layers of the North Field extend well into Qatari land in Ras Laffan.

Studies and well tests have also confirmed the ability to produce large quantities of gas from this new sector of the North Field. These are very important findings, which will have a great positive impact on Qatar’s gas industry, and which will move it forward into bigger and wider horizons.”

RoboVent redesigns popular weld fume extractor RoboVent has re-designed one of its most popular weld fume extraction systems as the first part of a new wave of product launches and organizational updates leading into 2020 from the Michigan-based company.

Each Spire unit provides filtration for up to two robotic weld cells for effective source capture filtration or easily converted to an ambient unit for area-wide filtration when a hooded enclosure is not possible.

RoboVent President Rick Kreczmer said, “We’ve retained the name of the unit and the 3’x3’ footprint that our customers love about the Spire. However, we completely re-engineered the Spire for better pulsing, longer lasting filters and easy maintenance features

our customers requested.

We made substantial improvements to make filter changes and dust disposal easy and upgraded our touchscreen controls to a huge 7” screen–customers that liked the old Spire will love the new Spire.”

The new Spire has a 7” full color HMI Touchscreen, for easier user operation; variable speed drive, to save energy and extend filter life; 3ft x 3ft footprint; moveable control panel, to make installation and access easier; upgraded dust containment, which means production can run longer and dust removal is simple; RoboVent PleatLock Filters, for longer filter life and easier change-outs, and improved filter pulsing to minimize filter pressure build up, extending filter life.

Mike Meyer, EVP of Engineering & Technical Services at RoboVent, said, “This is one of the best product launches I’ve been part of. The new Spire was produced with a collaborative effort of end users, specifying engineers, industry influencers and consultants and every part of our organization. Together we took everything we knew, challenged it and created the next generation of dust collectors for welding operations.”

This latest innovation through Spire is the first of several new and enhanced products RoboVent will be launching in 2020. ©

NorTECH not only sells, but educates Norco looks to foster relationships at center for latest robotic and welding equipment

By Nick Parkinson

N

orco’s NorTECH facility is serving a few roles for North America’s largest independent distributor.

The state-of-the-art NorTECH training and automation center is not only a place for students and customers’ employees to train and use the latest automation, productivity and safety enhancing equipment. NorTECH, which is in the Salt Lake City area, is also a selling tool, a place where customers can come and try the equipment for themselves before purchasing.

“NorTECH is our window to the market for that high-end equipment,” Robert Mohr Gerry, Executive Vice President, Industrial Division, at Norco Inc., told gasworld. “The center is designed to accomplish a couple different things, one of them is the community connection and education, and we bring in the institutions. The high schools can’t afford any equipment like this, some of the tech schools can’t afford a robot or a $200,000 cutting table. We can bring those people through and give them experience of this type of equipment, expose the student and faculty to what is out there.

“The center is also a selling tool. There’s nothing like it – you probably have to get past the Rockies east, and the Chicago marketplace where Praxair has one, so we wanted to have this place where we could

“Instead of pushing merchandise, we try to sell them on the concept of changing their business” bring customers and sell them on things to make their business more productive and equipment they haven’t seen operated, get them out of their day-to-day firefighting, see a better process. In a labor-constrained America, which is what we are in today with low unemployment, businesses need to adapt to that and they need to look to ways which doesn’t rely on labor. America has decided we’re not going to ship everything to China, so fabricators have to be very productive and we’re trying to help them get there.”

Norco, a Northwest-based independent distributor of welding and safety gases and supplies with 70+ locations and 1300+ employees, as well as two air separation units, hopes to gain the trust and loyalty of some of its younger visitors to the twoyear-old, 13,000 square foot NorTECH. For over 70 years, Norco’s motto has been the same ‘Serving You Better’ and as an Employee Owned company we embrace change and are excited about these market

opportunities. “In the old industrial selling program you have a guy pounding the streets and he shakes hands with someone on a floor level of a business and maybe become friends, and then sells them goods, maybe for 20 years, and typically you sell them the same goods,” Gerry said.

“Part of what NorTECH is trying to do is to get communication at a higher level of the organization so we can have an executive conversation. Instead of pushing merchandise, we try to sell them on the concept of changing their business and what it might mean to them. Then we have stronger relationships inside the company. You’re talking about selling higher in the stream on the customer side. It just creates a massive amount of stickiness with us inside that customer base when they rely on us for knowledge, updated equipment and how the future might look with their business.”

Norco sees its hands-on training as a valuable tool to increase knowledge and employee retention while giving students the opportunity to learn new skills in real world conditions, from experienced industry professionals. This includes individualized attention and valuable feedback from subject matter experts who are ready to answer questions and provide practical help. Delivering immediate feedback, augmented reality welding systems at NorTECH allow the user to experience the most realistic multiprocess welding simulation available, and build a more skilled workforce.

“Automation is no longer the future, it’s arrived,” Elias Margonis, Norco Inc. President, told gasworld.

“It’s just a matter of customers, fabricators, having the service level and the support in the change process. A lot of people want this but don’t know how to do it. It’s about people, and that has been Norco’s strength. It’s not just sales of the equipment, it’s the support of the change gasworld.com/distributorzone

and the recommendations and building a partnership. It’s about helping our existing customers with that change process.”

High-end equipment NorTECH has the latest in robotic welding solutions, large scale welding manipulators, advanced process submerged arc welding assembly stations, leading edge high definition plasma cutting equipment, weld fume extraction and dust collection equipment, as well as a very specific set of safety offerings.

“In the center at any moment in time we have from $20,000 high definition plasma cutting tables up to a $200,0000 high definition plasma cutting tables,” Gerry said. “We have another partner that is Irco Automation sub arc system, which is really high definition, you can maneuver the boom around, that’s up to $200,000 piece of equipment as well, then we have ALM Positioners for jigs, turning and rolling, we have three distinct air filtration systems from the more manual to the ones that are bolted into the ceiling, we have the Miller robotic cell, we have the whole range of Miller’s digital weld equipment. We also have another area dedicated to safety and we have a beverage center with all the mixers and blenders. We also have our vending offering and specialty gas displays.”

As for the education on offer, classes can be designed around a specific vendor.

“Sometimes we build specific classes around a particular vendor, for example Hypertherm, and we might do a seminar on how to get maximum use out of your consumables and how to maximize the equipment you have purchased,” Gerry

said. “It’s education at a higher level than just selling a customer equipment and then telling them to go and play with it.

We try to position Norco as the knowledge expert and that puts us in a good place with the customer – they buy from us because we provide something more than just a product. We have a classroom set up there and we do certifications for other things that we might not even be selling, like the safety side of the business.”

Norco, along with Miller Electric, is also in a partnership with Roosevelt, Utah-based UBTech. Norco allows students to learn how to use machines and equipment at NorTECH. The partnership allows students to work on their welding skills and experience, readying them for the workplace.

“The students get a certain amount of time inside of our NorTECH center and can play for the day,” Gerry said. “We also give them access to our staff at the NorTECH facility so access to NorTECH is part of the partnership offering. The value to Norco is serving the community and partnerships. The technical colleges

are getting more funding in the last couple years because of this resurgence of bluecollar work and we have helped feed that.

“It’s also a branding thing. If the students that are going to go into welding see Norco and Miller and see us doing good work for them and the community, that’s a great association and we only hope it sticks with them for a lifetime.

Those students might go from welders, to managers, and to owners who run fab shops. If they are our friends when they are 18 they should be our friends when they are 50. For folks that stay in our market, that’s a ton of brand recognition.”

As well as students, NorTECH is also used by Norco’s own employees.

“If you are just in a branch in a small town and you work for Norco for five years, as an individual we can tell you our capabilities but until you see them and get a chance to run a robot you don’t get a sense of our scope and size and capabilities,” Gerry said.

Norco plans to keep its equipment portfolio refreshed, and to increasingly use it to drive business.

“NorTECH does not happen by accident,” Margonis said. “It’s a strategic program for Norco’s industrial business and it’s all about customers, people, and service. We monitor the cadence of activities in the facility on a monthly basis and we target developments. We also learn from these customer experiences to make future ones better. We do our best to generate success for our customers and further develop our employees to continue delivering on ‘serving you better’.” gw

SPECIAL FEATURE | COBOTS

The era of the cobot is here Automation can ease labor shortage, attract younger workers – but will it also take jobs?

By Nick Parkinson

R

obots are increasingly being utilized in the manufacturing industry, but there are plenty who are still cautious about deploying robot coworkers, concerned that automation will displace jobs as well as posing a safety risk in the workplace.

Had those doubters been at FABTECH 2019 in November, they would have been able to see first-hand the potential of cobots which include the collaborative robot arms from Universal Robots (UR) that are being utilized by BotX Welder from Hirebotics, Red-D-Arc and Airgas; Vectis Automation’s Cobot Welding Tool; and SnapCut from ARC Specialties.

One potential, big benefit to these 20 | gasworld US Edition • January 2020

collaborative robots (known as cobots), which are robots engineered to work alongside humans, is how they can help address a labor shortage and an aging working force. The American Welding Society (AWS) estimates there will be a deficit of 200,000 welders this year, and double that by 2024. But cobots can fill some of those vacancies, especially for repetitive jobs, according to those in the cobot market.

Mitch Dupon, Application Development Engineer, Universal Robots USA, Inc., told gasworld, “Industry is desperate to find a solution to the lack of skilled welders for the current demand, looking forward to the future

is even scarier as the old guard retires and there isn’t anyone to replace them.

There is a market unserved by traditional automation that is being served by collaborative automation and they are seeing the benefits, the future looks bright for those willing to embrace the collaborative future.

“The robots enable a company to quote more work, control consumable costs and increase quality. This leads to a more secure work environment. They give opportunity for skill development and promotion opportunities for workers and for the company to hire easier to find workers to backfill those positions.

Most important, cobotic welders are gasworld.com/specialfeatures

tools in the hands of the skilled welder.

The skilled welder can employ the cobot welder to do mundane welding tasks while the manual welder focuses on the value added welding tasks.”

Cobot vendors and manufacturers argue the machines can create new roles, rather than eliminating jobs from the welding industry.

Josh Pawley, director of business development and co-founder of Fort Collins, Colorado-based Vectis Automation, told gasworld, “I don’t see cobots taking any jobs. I think we’ll continue to see the ‘Now Hiring Welders’ sign in front of each shop that a cobot goes in to. Key to this is that cobots can’t weld every application – there are many applications that are not fit for a cobot but are well-suited for the manual welder.

The idea behind collaborative welding is to have the cobot handle the repetitive, boring parts so the skilled welder can focus on the skilled weldments.”

What cobots will do, if adopted, is transform the nature of jobs a skilled welder does. “Automation has shown that for decades we’ve been treating human workers like robots,” Rob Goldiez, cofounder of Nashville, Tennessee-based Hirebotics, told gasworld.

“When we ask humans to do the same work day after day, week after week, without error and as efficiently as possible… we’re describing work best suited for automation but we’re asking humans to perform it. This treatment of human workers can easily lead to mistakes, burnout, turnover, safety issues, animosity towards management,

“The idea behind collaborative welding is to have the cobot handle the repetitive, boring parts so the skilled welder can focus on the skilled weldments”

and more. By unlocking robotics for more applications, BotX is allowing manufacturers, managers, and employees to break this trend. Let the BotX work on the repetitive work while your human workers are working on the unique parts, preparing new parts, or doing other high value tasks instead of the repetitive work.”

Goldiez believes cobots can build trust between humans and workers on the shop floor, to avoid feelings of humans versus robots, like something from The Terminator.

“Cobot welders like BotX fill a void in the market between large, complex traditional robots that are best suited for extremely large volume where cycle time is critical and human workers who have the highest levels of job satisfaction when using their problem-solving skills,” Goldiez told gasworld.

“Cobots free up human workers to spend their valuable time solving problems and doing unique work instead of working like a robot on lower volume, but still repetitive, parts.

“Traditional robots require expert programmers and large safety cages which creates distance between the human and the robot. These spatial barriers can easily create animosity between human workers and robots.

Even worse, if your trusted human workers are not integral to your automation strategy you are creating gaps in understanding and capabilities of automation with your workforce. The BotX Welder is designed to empower the human welder. Your skilled welder will work side-by-side with BotX teaching

new parts and letting the BotX Welder do what it does best – repetitive work.”

Other benefits Other reasons to invest in cobots include ease-of-use, versatility, portability, safety, lower costs, and increased capacity.

New tax incentives to encourage more spending on automation, as well as the latest automation software, has also led to a wider deployment of robotics, including small job shops. Higher quality parts and more repeatable processes produce increased efficiencies in product development, as labor and time spent fitting up inconsistent parts decreases, along with waste from over-welding, like excess filler metal and shielding gas.

Vectis Automation’s Cobot Welding Tool – which is powered by Universal Robots’ UR10e and was launched at FABTECH 2019 – is commonly 25-40% less expensive than the all-in cost of a small traditional robot welder. Vectis’ Let’s Weld TogetherTM intuitive programming interface is accessible directly through the UR cobot’s own teach pendant. Programs can be created, saved, and later recalled in order to handle the numerous part numbers typical for high mix/low volume shops. At FABTECH, gasworld was given the opportunity to make its own welding program using Vectis Automation’s Cobot Welding Tool, and to experience its ease-of-use. Vectis recommends the most efficient deployment of automation to be on the smaller, simpler, repetitive parts.

“The Vectis Cobot Welding Tool is helpful for automating small parts, subassemblies, or even sections of larger January 2020 • gasworld US Edition | 21

SPECIAL FEATURE | COBOTS

parts since it is portable,” Pawley said.

“Oftentimes, the temptation is to automate the large or complex weldment, but cobots are best suited for handling the ‘boring’ smaller parts and allowing the skilled welders to work on the skilled weldments. This also generates buy-in from the shop floor as well, as most welders hate welding those pallets of piece parts or subassemblies.”

The BotX Welder – developed by Hirebotics, Red-D-Arc, and Airgas – offers the opportunity to hire a robot welder by the hour and utilizes a UR10e cobot for simplicity of programming with cloud monitoring while avoiding the cost of ownership. Manufacturers pay only for the hours the system actually welds, which is ideal for seasonal work or

sudden loss of business.

“Our software empowers companies with short run production needs to quickly improve quality, consistency and output by leveraging their existing skilled welders,” Goldiez said.

Cobots also have a smaller footprint compared to traditional, large industrial robots in a welding application which are rigidly mounted to a workcell purposed with one task only and are often isolated from workers for safety by barriers or a cage. A cobot, however, can flexibly be applied to several tasks on the same day in a low-volume, high-mix job shop.

Goldiez said, “The fact that they’re collaborative and don’t require safety fencing like traditional industrial robots means a smaller footprint for

“The fact that they’re collaborative and don’t require safety fencing like traditional industrial robots means a smaller footprint for the equivalent working space, less floor space to produce same size part” the equivalent working space, less floor space to produce same size part. In many cases less than half the floor space of traditional automation.”

Customers can teach BotX the required welds simply via an app on any smartphone or tablet utilizing a library of welding recipes contained in the BotX software developed specifically for the BotX and optimized to work with Airgas’ ARCAL shielding gas. The Hirebotics mobile app allows the welder instead of a programmer to set up new parts in an easy-to-use, friendly interface.

Users can monitor their BotX Welder from anywhere in the world via realtime charts and dashboards, monitor consumables, and track live progress of the current weld sequence.

“One of the key benefits of building the BotX Welder on the Universal Robots platform is kinetic teaching,” Goldiez said.

“Also, customers can use the mobile app to engage with Hirebotics automation experts as well as Red-D-Arc, Airgas, and Air Liquide welding experts. The Hirebotics mobile app gives customers immediate access to help and support, at any time of the day or night.”

Bridging the generation gap There is also the theory that cobots can contribute to closing the generation gap.

The average age of today’s welder in the US is 55, with less than 20% under the age of 35, according to the AWS. gasworld.com/specialfeatures

“We absolutely believe that cobots will entice younger generations to get involved in and excited about manufacturing,” Pawley said.

“At the same time, the cobot welding tool can provide a conduit for experienced welders to pass on their immense welding knowledge. Combined, these two facts will allow different generations to work together to solve a common issue – boosting productivity. This exact scenario actually happened recently at one of our customers. The owner said he came back from a meeting to see his most experienced welder working together with a new-hire recent college graduate.

The college graduate was leading the programming effort and she was excited about fixturing/layout/sequencing, etc – while the welder with 40 years of experience under the hood was guiding the weld parameter development. It was inspiring to hear a piece of equipment bringing two generations together for a common goal.”

Attitudes are changing towards automation, and more companies are making the jump to automation. Hector Villarreal, President of Illinois-based Weldcoa, a manufacturer of products that store, transport, fill or analyze compressed gas cylinders or cryogenic liquids, told gasworld, “It’s funny, for the first half of my 25 years in this industry I traveled the world telling people, automation is affordable, reliable and can help you grow your business. And then one day, about 10 years ago, people started to call me asking me what kind of automation they should invest in. The changing mindset towards automation has really been amazing.

“About eight years ago I added two slides to my presentations on automation, and one was on Rethink Robotics. At that time, they had come out with the first ever commercially available co-operative robot.

Up to that point I’d never seen a robot that was designed to work with people.

The concept made sense to me, so I added a short video of the robot at work with people to my presentation.

“The other slide was on IBM’s Watson AI. I found it remarkable that Watson

had beat humans on the TV Gameshow Jeopardy! So, I added five minutes on AI technology. At the time people thought I was kidding about the commercial potential for both technologies. Which today is funny but back then was unimaginable for most people. That’s when I realized that the problem wasn’t the complexity that came with the technology.

The problem is that most people can’t imagine how to use the technology until someone shows them how it can be applied to their business.”

And cobots received a lot of interest at FABTECH in Chicago a couple months ago as more consider it an option for 2020.

“At FABTECH, we continually heard ‘I can’t find skilled labor’,” Pawley said.

“Many of those manufacturers have been stuck between a rock and a hard place – unable to find skilled labor while simultaneously unable to justify, hire programmers for, or take the leap into traditional automation. With the UR-powered Vectis Cobot Welding Tool, those manufacturers now have an affordable, versatile, and compact robotic welding option with a quick lead time, DIY setup and programming, and a 30-

day return policy to minimize their risk.”

Challenges ahead More metal fabricating companies might be making the jump to automation – but it comes with its own challenges. Gaining the customer’s trust when it comes to robots, or cobots, is a big one.

“The main challenge will be changing how people react to the word robot,” Dupon said.

“Using cobot helps this task, however, people still approach the conversation about cobots from a traditional robot mindset. This is a different way of thinking and it takes a fresh approach.”

Goldiez said, “Automation has an allure to manufacturers struggling to find and retain skilled employees, dealing with quality issues, or trying to reduce costs. But automation brings new challenges for many companies.

Someone at the company must deal with robot programming, integration to other equipment, gripper design, part presentation, and more.”

First, though, is the challenge to convince industry to embrace the rise of the cobots. gw January 2020 • gasworld US Edition | 23

SPECIAL FEATURE | INDIANA OXYGEN COMPANY

Making a success of online retail Indiana Oxygen Company’s e-commerce business is thriving. Here’s how they do it…

By Nick Parkinson

I

ndiana Oxygen Company (IOC) is an old company with a modern-day vision. When it comes to selling welding equipment and supplies online, no one is doing it better than IOC. The Indianapolis-based company is the oldest gas and welding supply distributor in the US and its 13 branches serve a five-state region, but its online store weldingsuppliesfromioc.com serves customers further afield, and even overseas. As well as gaining customers, it also received recognition last year (2019).

Newsweek, the weekly magazine, ranked IOC’s welding supplies site fifth in the category of “DIY, Tools, Supplies,” above any other welding supply only store, in a survey of more than 9,500 online shops in the US, compiled by Statista, Inc., the global data-research firm, published in the September 27th issue. IOC received a score higher than the likes of Amazon, Costco, and Walmart in the Newsweek poll.

The ease and convenience of shopping online means e-commerce will continue to grow. Wally Brant, CEO of Indiana Oxygen Company and grandson of founder Walter Brant, has seen many twists and turns after 40 years in the industry and believes online stores can co-exist with traditional bricks and mortar store, rather than put them out of business.

“Very definitely, the future has a place for selling welding equipment online, but at the same time it does not spell the end of the brick and mortars,” Brant told gasworld.

24 | gasworld US Edition • January 2020

“I feel there will be a healthy future for both. The initial trajectory which spelt doom and gloom for all the brick and mortars has been redefined. My view is that all of retail is broken down into two categories: there are things that you want, and things that you have to have. For example, if you are looking for a new pair of shoes, or book, you want those, you don’t have to have them. The chances are you will go online for those because of convenience and selection. But if you are a contractor in the middle of a welding job and you run out of welding rod, you have to have it now. There will always be a place for brick and mortar stores like ours, hardware stores and drugs stores. We just happen to fall into that category that covers both the ‘have to have it’ and ‘want to have it’ buyers.”

Despite more and more people opting to do their shopping online, there are still advantages to buying in a store.

Brant explained, “We say that if you want the online deal you have to get the product on the internet, and if you want the one that is on the floor you have to pay the price that is on the floor because we are going to help you set it up, we’re going to help you learn how to use it, tell you the right type of wire and gases, and there’s a price for that. When you go online, even though you are getting a lot of expertise from the people answering the phone, it still comes down to a brown box at the end of the driveway.”

Taking on Amazon The personal touch and expertise in the sector are what sets apart IOC from its gasworld.com/specialfeatures

“You’re never going to compete with Amazon on their terms, our industry can’t, but we can beat them on customer service and expert knowledge” rivals, according to Brant and Justin Yoder, IOC’s Chief Digital Officer.

“We have that customer service element – we strive to ensure that everyone that calls gets a live person with knowledge of the products we sell. You’re never going to compete with Amazon on their terms, our industry can’t, but we can beat them on customer service and expert knowledge.

Those things are central to our wellbeing,” Yoder told gasworld.

“Amazon is big enough to shape what the customer expects the online experience to be, so that is our starting point. We have to have a site that is easy to navigate, people have to know stores, and they think they know what if something is in stock and we have to they want. It comes down to our online or ship it quickly. It has to be easy to check brick and mortar businesses to add some out, we have to communicate when it is shipped, it has to be trackable, and returns value to their visit and maybe steer them in a slightly different direction if they are a have to be easy.

“One of the things we have IOC has a full-time, fourseen in the last few years is a person team ready to answer lot of consumers are starting their search online now. Walking into a welding customers’ telephone calls, emails, or live chats about products, orders, or any other supply shop is intimidating for people questions they have.

Buyers arrive at our “Anyone can throw up a website and virtual store, or our brick and mortar

“One of our successes is that we have knowledgeable people, real live human beings, on the other end of the phone who can answer questions from people/ customers who may not know what they are looking for. If I order a book on Amazon, their algorithm might suggest a few similar options. But what’s missing is the chance to have someone listen to me and make a recommendation based on our conversation. That’s what we can offer that Amazon can’t.”

Challenges Online sales account for approximately a third of IOC’s business, which is nationwide and also ships to “to about a dozen different countries”. But there are challenges, one being margin preservation.

“As more and more retailers come into the market, price or freebees like helmets, jackets, or gloves becomes the easiest way January 2020 • gasworld US Edition | 25

to get a sale,” Yoder said.

“Margin preservation is one of our biggest challenges because we have to keep the lights on, we have to pay our people, and we run it like a stand-alone business rather than this novelty of moving product just because it’s online.”

For Brant, maintaining a successful presence online in a crowded marketplace is like the video parlor

26 | gasworld US Edition • January 2020

game Whac-A-Mole; new challenges constantly pop up and you have to be ready to quickly respond.

“Every day is a new challenge where a competitor or manufacturer will throw a twist and we have to counter that immediately,” Brant said.

“One of the things, for example, is MAP pricing (minimum advertised pricing). We are very big proponents of MAP and we get a little upset when some of the other online companies try to go around on the rule by offering a discount or freebees in addition to what you are selling at minimum advertised pricing.

When the price drops once you add an item to your cart or you get a whole bunch of accessories for free, we feel like that’s cheating. We are big proponents of MAP pricing because we feel a responsibility to the market and to be able to have margins in there so we can continue to offer a premier level of service.”

Another mole to pop up, or challenge, is sales tax on out-of-state online sellers.

“Having to navigate the tax codes of something like 39 states where we remit was a big burden for us this year [2019],” Yoder said.

“We are big proponents of MAP pricing because we feel a responsibility to the market and to be able to have margins...”

“You could have a full-time tax specialist on hand to make sure you are collecting and remitting the right amount.”

IOC plans to open up its e-commerce business to its existing customers.

“Our plans to expand include moving into the business to business (B2B) realm,” Yoder said.

“We’re trying take the experience from the business to consumer (B2C) side to the B2B so that our existing customers can have this rich shopping experience with all the things they have come to expect from their online experience, like their own pricing, cylinder balances, paying bills, viewing past orders. The expansion to the business to business (B2B) will be new to us. We’re trying to make this an attractive thing for all of our customers,” Brant added. gw gasworld.com/specialfeatures

Controlling gas surge

By Curt Rocha, Global Product and Business Director – Gas Control Equipment, ESAB

I

Found money The rate of waste varies widely, but on average, most operations could realize a gas savings of 20 to 40% by controlling gas surges using two common solutions.

One solution is a surge limiting regulator (North American term) or a “gas economiser” (EU term). These devices connect to the shielding gas inlet (see Figure 2). Using a fixed or adjustable orifice, they limit the maximum gas flow rate at the end of the 28 | gasworld US Edition • January 2020

Figure 1: Surge Flow Chart TYPICAL OF SHIELDING GAS SAVED USING SURGE LIMITING REGULATOR

CUBIC FEET PER HOUR

s that “whoooshhhh” sound the start of gas shielding pre-flow, or is it the sound of flushing money down the drain? Unfortunately, it’s probably the latter, as gas surges during arc start are a common – yet accepted – problem in many welding operations.

After the solenoid valve on the welding machine or wire feeder closes, gas pressure in the hose continues to build up until back pressure stops the flow of gas. The gas hose may even expand a fraction of an inch. Like pinched fingers releasing a swollen balloon, the next opening of the solenoid valve allows a blast of compressed gas to exit the MIG gun or TIG torch at 80 to 120 CFH (2265 to 3398 l3/min) or more (Figure 1). As we’ll discuss later in this article, more is not better when it comes to gas flow.

Operations that require short intervals between arc starts will experience less surge, but even a few minutes of idle time will allow the pressure to build back up. Those operations using larger diameter and longer gas hoses have more potential for waste.

TIME IN SECONDS AFTER EACH TRIGGERING

Gas surge flow rates can easily reach three to six times the recommended flow rates for TIG welding or MIG/flux cored welding. Source: ESAB

“Spot welding applications tend to save more gas (an average of 40 to 45%), where seam welding operations save about 20%...” gas line, such as to 50 CFH. These are “install it and forget it” devices because they are extremely durable (Figure 3).

Another solution is a “cylinder regulator ecosaver,” which combines the surge limiting regulator principle into

an adjustable flow meter with a pressure gauge to ensure a consistent flow rate (also Figure 3). They make more sense when operators want to adjust gas flow, such as when switching between solid and cored wires. Ecosavers can reduce gas waste by 0.018 cu. ft. (0.5 l3) per weld. Spot welding applications tend to save more gas (an average of 40 to 45%), where seam welding operations save about 20%.

ESAB recently worked with a large transportation equipment manufacturer using 100% CO2 shielding gas for their flux cored welding operation that spent approximately $250,000 annually on CO2 at one location. By investing $27,500 to install surge limiting regulators, the manufacturer reduced gasworld.com/specialfeatures

annual shielding gas costs by $75,000, a savings of 30%.

While a 30% savings might not mean that much to a shop with just a few welding stations, the hassle of fewer cylinder swap-outs — especially annoying when gas runs out in the middle of a project — will be well worth the small investment for a surge limiting device. By optimizing gas use, fabricators may also be able to reduce the number of spare cylinders in stock, reduce rental charges and reduce the frequency of cylinder delivery.

Quality control As noted earlier, more is not better when it comes to gas flow. Yes, a welding system can have restrictions in the gas flow (e.g., damaged or clogged torch cables), need a bit of overpressure to compensate for a long line or need a little more or less gas flow depending on © ESAB | Surge limiting regulators are available with and without pressure gauges

consumable choice (as a cautionary side note, always re-evaluate gas flow rates when changing consumable types).

Increasing gas flow beyond the recommended rate, whether intentionally or due to a gas surge, is almost guaranteed to cause weld quality issues. Worse, these issues may be hard to diagnose.

For example, one California structural steel fabricator had switched to a different brand of E71T-1 gas shielded flux cored wire.

After the switch, they began experiencing gas marks (commonly called “worm tracks”) at the beginning of their welds, and it was a painful source of rework. After trying the typical cures for eliminating worm tracks without success (adjusting voltage, electrical stickout, changing cylinders, changing torch angle, etc.), the fabricator believed they had received a pallet of wire that had either moisture absorption issues or a manufacturing defect.

Fortunately, the welding supply distributor and filler metal manufacturer team were able to diagnose the real problem as gas surges. The new filler metal had a faster-freezing slag system that trapped excess gas between the weld puddle and the slag, creating worm tracks. Installing surge limiting regulators

solved the problem, and eliminating the time spent repairing welding defects provided an instant savings.

Gas surges commonly cause porosity when MIG welding, as the turbulent, swirling gas flow pulls in outside atmospheric contaminates. Thinking poor gas coverage caused porosity, operators increase flow rates to a point where they compound contamination problems: gas surges during arc start create porosity at the beginning of the weld and then turbulent flow during welding causes random porosity.

As one aerospace fabricator learned, gas surges may also cause burn-though issues when TIG welding an extremely thin part at low amperage.

At the time, their welding power source had a minimum output current of 10 amps, and the fabricator thought it would need to purchase a power source with an output of 5 amps or less to complete the project. Fortunately, a low-cost surge limiting regulator solved the problem, which was actually caused by excess volume of ionized gas.

For any fabricator who now suspects they might have an issue related to gas surges, ask your manufacturer’s representative or welding supply distributor to conduct a flow test. The procedure is simple, and the solutions are easy to apply. © ESAB

ESAB STRENGTHENS GLOBAL GAS PRESENCE Since Maryland-based ESAB Welding & Cutting Products completed its acquisition of Sweden-based Gas Control Equipment in October 2018, the company has focused on aligning its global product offerings and innovations into four focus areas: cutting and welding, central gas systems, cylinder valves and healthcare.

“We now have the industry’s broadest portfolio of products, as well as the broadest range of products within those portfolios,” said Christophe de Fitte, CEO of the GCE Group since January 2014.

“With respect to the European and North American markets, we’ve been working to identify gaps and see how our combined resources can best meet the needs of our distribution partners and end users.”

ESAB employs more than 8,700 people and operates in the EU, Middle East and Africa, Asia-Pacific and North and South America.

Specialty gas and healthcare North American distributors now have full access to GCE products, notably the GCE Druva and GCE Valves product lines. Specialty gas products within the line include regulators, manifolds, valves and accessories for high-purity © gasworld | ESAB’s exhibition at FABTECH in November

© ESAB | Innovative products include the Victor EDGE 2.0. Launched in North America and coming soon to the EU, unique benefits include a design that enables operators to more easily set and see delivery and cylinder pressures while offering unmatched safety benefits

and ultra-high-purity applications found in laboratories, petrochemical and semiconductor manufacturing.

Curt Rocha, Global Product and Business Director Gas Equipment for ESAB adds that, “GCE medical and healthcare products coming to North America include the Zen-O™ portable oxygen concentrators (POCs), which deliver up to two liters of oxygen per minute to support people with respiratory disorders.” The US market size for POCs will reach $1.051bn by 2026, according to Zion Market Research.

ESAB will support distributors with specialists for the specialty gas, valves, and healthcare lines. Other activities for 2020 include upgrading the clean room at ESAB’s Denton, Texas, facility.

“Distributors know Denton for

its heritage with Victor cutting and welding products, but it also has a separate specialty gas lab where we’ll add more assembly and testing equipment and make other enhancements to support our expanded North American portfolio,” said Rocha.

Innovation Prior to the GCE acquisition, ESAB’s main strength in its gas equipment portfolio especially came from the Victor® brand, which has served the industrial cutting and welding markets since 1913, and the company’s EU portfolio now reflects that strength.

“Starting in Q2 2020, we will offer the innovative Victor EDGE™ 2.0 regulators in Europe,” said Rocha. “No other regulator on the market offers its combination of safety, durability, performance and usability.”

Designed for controlling the flow of oxygen, acetylene, argon, air, nitrogen and other industrial gases, EDGE 2.0 features the Patented SLAM™ (Shock Limitation and Absorption Mechanism) technology built into the adjusting knob. SLAM permits the knob to absorb the impact in the event of a cylinder fall, helping prevent catastrophic failure.

“GCE and ESAB share a history of new product introductions and innovations such as the Zen-O and EDGE 2.0, and we will retain this focus moving forward,” said de Fitte. gw gasworld.com/specialfeatures

SPECIAL FEATURE | WELD FUME MITIGATION

Clearing the air for tank manufacturers

By Adam Pfeiffer, Field Solutions Director for RoboVent

R

egardless of industry, manufacturers that depend on high volume welding production agree on one thing: weld fumes are bad news. The toxic elements in weld smoke threaten employee health.

When inhaled, weld fumes may cause upper respiratory ailments and greatly increase the risk of serious diseases including COPD and cancer.

Weld fumes produce some of the most dangerous airborne contaminants found in manufacturing facilities today. The high temperatures needed for welding create fumes containing exceedingly small particulates. While most of these particulates come from the weld wire, some are from the base materials.

Particulates from base metals such as manganese and hexavalent chromium are extremely toxic and very dangerous when inhaled.

Manganese is a trace element found in many kinds of welding. Breathing its particulates can cause “manganism”, a neurological condition similar to Parkinson’s disease. Hexavalent chromium is found in fumes coming from welded metals that include chromium, such as stainless steel. These particulates can be highly irritating to the eyes, nose and throat. Hexavalent chromium is also a known carcinogen. Light metals in weld fumes, such as beryllium and aluminum, can also cause health problems when inhaled, including the risk of lung cancer.

Every manufacturer that utilizes high volume welding is vulnerable to the dangers of weld fumes. Fume mitigation and air quality control are a necessity.

Fortunately, today’s air filtration systems are powerful, efficient and customizable 32 | gasworld US Edition • January 2020

“Customization is important, particularly for tank manufacturing and other industries where clearing the air poses some special challenges” for any welding environment.

Customization is important, particularly for tank manufacturing and other industries where clearing the air poses some special challenges. The key is finding the best solution for a specific welding application.

Ambient air capture provides total-plant solution Tank manufacturers fabricate storage tanks, cylinders and pressure vessels for many industries including oil and gas, transportation, food and beverage, and chemicals. Every industry has its own requirements, and while the volume and composition of weld fumes depends on the material and processes used, toxic elements such as hexavalent chromium, manganese, nickel and beryllium are often present.

Storage tanks for the oil and gas industry, for example, are massive weldments. They are too large to be contained under a fume hood and may require the use of overhead cranes.

As a result, capturing weld fumes at their source, which is usually the most economical and effective method of air gasworld.com/specialfeatures

quality control, presents an extremely difficult challenge. Also, large storage tanks, valves and other components are often made of stainless steel which produces especially toxic weld fumes including hexavalent chromium. In this situation, one of the more common solutions for protecting welders and anyone else working in the vicinity of the work is ambient air capture and filtration combined perhaps with some Powered Air Purifying Respirators (PAPRs). Ambient systems will not immediately remove the fumes from the breathing zone as a source capture, backdraft-type design could.

While effective at clearing the air in a facility and reducing the overall particles in the air, ambient solutions clean the air in the general vicinity of the welding operation. There are typically three types of configurations that are used most widely: 1) A ducted push-pull system; 2) A ductless floor system, and/or 3) A ductless ceiling/wall-mounted system.

Each have their own distinct advantages.

A ducted push-pull system is the most traditional method. Ductwork is installed down one side of the room or space being addressed. Collection points installed in the ductwork at regular intervals where the fume stratifies carry the particulates to a filtration unit. Clean air is then pushed in through ductwork and registers on the other side of the room creating a laminar air flow pattern across the space. A ducted system uses centralized collectors which help save space. The filtration unit can even sit outside the building.

In comparison, a ductless push-pull system positions a standalone filtration unit – or array of units – near welding stations and collects fumes. The unit then returns cleaned air through strong

jets back into the facility. These filtration units are easy to install and can be moved around if needed. The Spire360, the Fusion Vortex and Vista360 are all examples of free-standing ductless dust collectors. The Spire sits on the floor and is placed strategically near key collection points and the Fusion and Vista can be suspended from the ceiling or wall mounted around the process to create an effective air flow pattern.

Ambient filtration systems provide total-plant solution for indoor ambient air quality. When source capture isn’t possible due to large custom components or overhead cranes, these systems can clean and recirculate the air in the entire plant without conflicting with these obstructions. By filtering and recirculating clean air, ambient systems also help avoid the costly energy bills associated with replacing the warm air that other systems simply exhaust from the building. These filtration solutions are both environmentally responsible and cost effective. No ductwork is required for freestanding, ductless filtration equipment which eliminates interference with overhead cranes or other obstructions while lowering installation cost as well..

Source capture safely extracts weld fumes in confined spaces The most effective capture method for weld fumes is source capture filtration.

If a process is automated or can be placed under or near a hood, a source capture solution is ideal – especially for welds happening on the exterior of the tank. Fabricating large storage tanks often requires manual welding

© RoboVent | Ambient units like the Vista360 can be mounted to the ceiling or hung from trusses in order to maximize floorspace for production capacity

inside enclosed spaces. Weld fumes can rapidly collect to dangerous levels in these conditions, greatly increasing the risk of toxic exposure. Weld smoke haze also accumulates quickly in confined spaces, affecting productivity and work quality. Fortunately, source capture – collecting fumes at the point of welding – is a proven way to reduce weld fumes where it is needed most. Welding guns with integrated fume extraction at the tip, such as the RoboVent Extractor™, provide a versatile solution for welding in confined spaces.

Combining these guns with a type of hi-vac extraction unit has proven to be an effective solution for capturing welding fumes generated at the source and help reduce the welder’s exposure to the fumes by up to 95%. The gun can be connected to a centrally placed extraction system, such as standalone hi-vac collection systems or to more portable fume extraction systems, like the MiniCube™.

With this type of flexibility, the Extractor can be used in many different work environments including large tanks.

Today, tank manufacturers have many fume extraction and air filtration options for their welding operations. Selecting the right solution for their specific applications will ensure a constant flow of clean, breathable air throughout their facility. gw ABOUT THE AUTHOR Adam Pfeiffer, Field Solutions Director for RoboVent, has been in welding and fume extraction industry for nearly 20 years and has designed hundreds of solutions for manufacturers in the US.

SPECIAL FEATURE | OXY-FUEL CUTTING

Oxy-fuel cutting process automation

By Martin Roubicek, Ph.D., Business Development Manager CWT at GCE Group

here is still significant potential for increasing the efficiency of oxy-fuel cutting technology. The higher level of process automation is a prerequisite.

Today’s cutting machines are automated systems, controlled by CNC with software, often ready for integration into production lines and units as Industry 4.0. We often see machines employing two or more different technologies, such as plasma, oxy-fuel, drilling, beveling, marking, etc.

The machine is a carrier of individual technologies that are automated in certain degree and require varying levels of operator experience. Of course, here too,

34 | gasworld US Edition • January 2020

the higher the degree of automation of the technological process, the less demands are placed on the equipment operator.

A comparison of plasma and oxy-fuel cutting technologies shows us a different approach to automation. Plasma cutting technologies are delivered in most cases as package containing all parts necessary for the operation of the process: hardware, software and process parameters. They are supplied to virtually all manufacturers of cutting machines by a couple of premium suppliers, specialized in the plasma process. That is, considerably simplified, the machine manufacturer buys complete plasma technology from

a specialized supplier and installs it on his machine. It is a really simplified view and the machine manufacturer shall invest substantial knowledge and effort to make the whole unit functioning according to the wishes of the user. But most conventional cutting machines can work with plasma technology in practice automatic mode.

In the case of oxy-fuel cutting it is much more demanding on the machine manufacturer. So far there has been no specialized supplier of the whole process on the market; there are only vendors of individual components such as torches, cutting nozzles, safety elements, hoses, valves, height sensors, lighters.

The machine manufacturer thus relies on own resources and knowledge in the design of oxy-fuel technology, component selection, finding and optimizing process parameters, etc. The result is then very different in different machine manufacturers, both in the level of automation of the cutting process and in the level of utilization of the technology in terms of cutting quality, cutting speed, sheet metal piercing ability.

Not every cutting machine manufacturer has an oxy-fuel cutting process so well managed that the machine can work alone, automatically, without significant intervention of the operator.

The issue is also dependent on the finances that the user is willing to invest in each technology. Often, we hear the sentence: “Everybody knows oxy-fuel cutting, it must be cheap”. But today’s reality is different. Given the general gasworld.com/specialfeatures

APC is arranged modularly for flexible assembly on the machine. The main components are:

Advantages for users: • High-speed oxygen cutting with cutting quality corresponding to the highest criteria of ISO 9013 • System integration minimizes the distance between two adjacent torches • It allows cutting near sheet metal edge or cutting kerf • Best-in-class height sensor for drytable cutting • Flashback detection to increase torch life • Slag detection on sheet metal surface • Automatic flame ignition is integrated into the torch

• Flame ignition detection • Tool-free replacement of consumables High productivity and production quality with APC The low operating costs per unit of cut length ensure the fastest return on investment. Automation is one of the decisive factors for this when using the optimum cutting machine and balanced components.

Cutting speed is the key for economic success. The latest design of cutting nozzles increases cutting speed. ASF and PSF high speed nozzles are among the best available on the market. Results can be even improved by using ARC and PRC nozzles which are the fastest in class. All types of cutting and heating nozzles are connected to the torch by the Tool-Free system manually, without tools. They ensure also the best possible cutting quality according to ISO 9013. The perpendicularity of the cut is guaranteed for the full range of sheet thickness from 3mm to 300mm on both sides of the cutting kerf. This is an indisputable advantage of oxygen cutting compared to other methods of thermal cutting of materials. Incorrect type or low-quality cutting or heating nozzle leads to a slower return on investment.

Then the user, along with strong marketing pressures, demands for him easier plasma technology even where oxygen would be more economical. An approximate comparison of the cost level of individual methods of thermal cutting of materials is shown in the graph, see Figure 1.

The higher degree of automation of the oxy-fuel cutting process and the elimination of dependence on operating personnel is thus a step towards better utilization of the process capabilities and its application in the areas of both economic and technological advantage.

SPECIAL FEATURE | OXY-FUEL CUTTING

Costs can be calculated in different ways, but ultimately the total cost per unit of cut length is significant rather than the amount of initial investment in equipment. The total costs include more components such as energy and gas consumption, consumables, labor, setting time, additional rework, etc.

When counting all together, oxy-fuel cutting is economically competitive with other cutting methods already from 25mm sheet thickness and should therefore be considered as the primary cutting technology there.

The latest statistics confirm this. The area of ​​greatest use for mechanized oxy-fuel cutting of unalloyed steels are thicknesses 20mm–60mm.

The fully automatic process brings additional benefits Integrated flame ignition: Automatic flame ignition speeds up the process and reduces gas consumption costs.

The flame can always be stopped automatically when the cut is finished and then easily reignited to start next cut. Such a start/stop system saves more energy and emissions than similar systems in cars when stopped at a traffic light. The ignition integrated in the torch guarantees reliability even when cutting thicker sheet metal, while being safely protected from the effects of molten slag. Manual flame ignition operations are not safe and efficient.

Slag detection: The slag always remains on the surface of the metal sheet after the previous piercing. So, there are two options: thorough slag removal by a designated operator manually, which

is costly, or the use APC with slag detection and automatic adjustment of cutting parameters.

Lifetime of consumables: Solid design of durable materials and the use of Coolex® system is an advantage.

Coolex® lowers equipment temperature by controlled cooling oxygen flow throughout the operating cycle. This increases both the lifetime of the cutting and heating nozzles and service life of the torch. A cooled equipment is more resistant to the effects of backfire.

Safe system: Knowing the right behavior and safety rules is very important when cutting. It is a whole set of knowledge in connection with technical gases, intense flame, high temperature, electrical energy, etc. One of APC’s advantages is that it contains a few integrated safety features and minimizes the risk behavior of the cutting machine operator. E.g. carefully selected types of the flashback arrestors are part of the APC system.

Flashback detection: Early detection of any risk is a prevention of material and equipment damage and, more importantly, a risk to personnel health. The detection of the sustained backfire minimizes the risk of endangering situations.

Conclusion The current APC is the first generation of a system that is constantly being developed and improved in cooperation with end-users, cutting machine producers, CNC and software companies, universities and innovation centers. The end goal is to give the chance to user for optimal cutting process selection for his application. The target is a cutting machine working without a qualified operator with adequate efficiency and repeatable quality of products. Such machine could then be integrated into Smart factories. gw gasworld.com/specialfeatures

Forerunner of the future The USS Albacore’s place in naval and welding history

By Agnes H. Baker

W

ith the motto Praenuntius Futuri (Forerunner of the Future), the USS Albacore was commissioned in 1953 as an experimental vessel to test submarine hydrodynamics and ended up revolutionizing submarine design. The pioneering shape of her hull, when combined with the nuclear power technology of the USS Nautilus resulted in the USS Skipjack, the first submarine capable of sustained underwater high performance.

Today, the USS Albacore is a National Historic Landmark and the centerpiece of Albacore Park in Portsmouth, NH, not far from the shipyard where she was built. This month, as part of gasworld’s examination of welding and automation applications, we take a look at how © USS Albacore Park | The USS Albacore Park

38 | gasworld US Edition • January 2020

this historic welded structure was instrumental in the introduction of new materials and the development of welding applications still in use today.

To learn more about what makes this submarine so significant, particularly from a fabrication perspective, gasworld met with Ken Herrick, President of the Portsmouth Submarine Memorial Association, Jim Arsenault, retired Superintendent of the Welding, Shipfitter and Sheet Metal Group at the Portsmouth Naval Shipyard, and Patti Violette, Executive Director/Curator of Albacore Park.

The need for speed Historically, US submarines were surface ships that occasionally dropped beneath the waves. They were slow and

difficult to maneuver. Ken Herrick, who worked as a Naval Architect Technician at the Portsmouth Naval Shipyard from 1959 until his retirement in 1998, explained that at the end of World War II, the US realized that German submarine technology had surpassed its own. Subsequently, a commission was established, the Committee on Undersea Warfare (CUW), to study submarine performance. CUW’s final report issued in 1949 strongly suggested that the Navy build a high-speed research submarine capable of exceeding 20 knots submerged.

Herrick related, “At this time, there were two very influential Admirals running the submarine side of Naval Ship Design Operations, Admiral Hyman G. Rickover and Admiral Charles Monson – ­ both of whom had very different priorities about submarine design. Rickover was after a new, air independent, propulsion system, and was uninterested in redesigning the characteristics of the ship itself.”

The nuclear-powered USS Nautilus was the result of Rickover’s efforts.

“Momsen wanted to improve capability,” said Herrick. “His goal was to build a submarine hull with underwater speed as the prime requirement. At the end of WWII, our subs could not keep up with a German destroyer or maneuver around them. They needed greater underwater speed and agility and these were Momsen goals.”

Momsen had a long history of forward thinking. A Navy expert on diving, he had invented the Momsen lung that enabled people to escape from submarines and was instrumental in gasworld.com/specialfeatures

“After more than 25 scale models were produced, the final version of the sub was shaped like a fish with a cod’s head and a mackerel’s tail” the design of the McCann Submarine Rescue Chamber. He also led the diving team that developed tables of helium and oxygen mixtures, which permitted divers to safely operate at depths greater than 300 feet.

In addition to be being a skilled designer, Momsen was an astute politician. In a carrier-focused Navy, he recognized the need to justify his ideas based on the defense of the fleet.

From his WWII experience he knew submarines were feared by carrier Admirals so he proposed building a target for submarine hunter-killer groups to practice on. That target was to become the Albacore.

Reverse engineering Some work on speed and maneuverability had already been done. According to Herrick, the Germans had developed a high speed class of submarine during WWII, known as the Type XXI U-Boat.

After the War, the US brought over two Type XXI subs from Germany.

“The Portsmouth Naval Shipyard reverse engineered one sub down to the last bolt and with the other the Navy formed and qualified a crew to conduct numerous, performance related, Sea Trials. We still have one of those crew members with us today,” said Herrick.

Six copies of the Type XXI sub were built, and while they were an improvement over the US’ WWII GUPPYs, tests showed only marginal increase in performance and capability.

According to Herrick, this was unacceptable to Momsen and he called for a 20-plus knot submarine. This represented a lofty goal. Subs at the end of WWII only could travel at 8-10 kts submerged and 10-15 kt on the surface.

Hull design Herrick described the three important elements of submarine hull design: (1) the shape of the nose, which pokes a

hole in the water; (2) the maximum diameter of the ship, which is the point at which the hole in the water stops getting any bigger; and (3) the shape of the stern, which determines the dynamics of the water’s collapse into the path of the propeller.

Determining the submarine’s shape was a huge concern to Momsen. He began the quest for speed by testing new hull designs in the huge Tow Tanks available at the Navy’s David Taylor Model Basin in Carderock, Maryland.

There the optimum hydrodynamic shape for underwater speed and maneuverability could be defined.

The team looked at successful aerospace designs for shape ideas. A form based on the British Experimental Airship R-101 became the model of choice and it was among the first shapes tested in the Langley Air Force Base’s wind tunnels in Hampton, Virginia.

There the resistance equations for the R-101 Airship, first developed by American scientist Hilda Lyon in 1929, were tested and confirmed. In the end, after more than 25 scale models were produced, the final version of the sub was shaped like a fish with a cod’s head and a mackerel’s tail.

Getting the sub built In an effort to gain as much freedom to design speed and maneuverability into the Albacore, Momsen decided that it would contain no ordinance. Without the Bureaus of Ordinance, Engineering, Navigation and Construction and Repair, Momsen remarked, the submarine would not end up like a “stuffed turkey.” His instructions to the designers, according to Albacore Park History, were: “Forget about surface performance. Think only about submerged capability which will provide the utmost speed with a minimum of power. When in doubt, think speed.”

As Deputy Chief of Naval Operations (Submarines) Momsen oversaw the building of the ship at the Portsmouth Naval Shipyard, the preeminent ship building facility in the county and one January 2020 • gasworld US Edition | 39

owned by the US government.

“I was at the shipyard during Albacore’s Phase II, and we were made aware that there would be lots of changes to this boat,” said Herrick.

“When we were instructed to make changes, we did. At a private shipyard you couldn’t do that. It would take weeks to get contracts settled. In all, the Albacore went through five building and design phases and the end product was everything everyone thought it would be,” said Herrick. “It was quieter, faster, and it could turn inside the turning radius of a destroyer, the most maneuverable ship in the squadron. The destroyer’s job is to defend the squadron from outside threat so it was critical that the sub could maneuver within its range.”

Making history According to the American Society of Mechanical Engineers (ASME) (asme.org), which has designated the USS Albacore as a Historic Mechanical Engineering Landmark, the Albacore represented a radical change in submarine design. It was “the first Navy-designed vessel with a true submarine hull form in which the surface characteristics were subordinated to requirements of underwater performance.

Its design innovations were adopted for all US Navy submarines that followed.”

“In recognition and triumph of this time-tested experimental submarine to serve as a prototype for the development

of contemporary Navy vessels, and in appreciation of its valuable contribution to the welding industry, symbolizing for all generations a continued vision into the future,” the USS Albacore also received the designation of Historic Welded Structure from the American Welding Society (aws.org).

According to Herrick, the construction of the Albacore using newly developed HY-80 steel gave it its historic significance from a fabrication perspective.

Herrick said, “As defined in Archimedes’ Principal, the weight of the hull factors into how deep a sub can go. Previous subs had been built with Mild steel, which has a pressure rating of 33,000 psi and High Tensile steel, which is rated at 55,000 psi.

The Navy was looking for something stronger. HY-80, rated at 80,000 psi, was developed by Lukens Steel, among other steel companies, for use in building submarines.”

“Different types of steel weigh about

“It was quieter, faster, and it could turn inside the turning radius of a destroyer, the most maneuverable ship in the squadron”

the same: 1/8-inch-thick steel weighs around 5.1 pounds per sq. ft. and 1-inch-thick steel around 40.8 pounds per sq. ft. We needed to make the hull more pressure resistant but not heavier,” continued Herrick.

“To go deeper using Mild or High Tensile steel in the hull, you had to increase the thickness of the hull and therefore the weight of the ship. HY-80, with a psi of 80,000, would allow the Navy to build subs that went deeper yet could retain the same underwater capability.”

Jim Arsenault, Retired Superintendent of Welding, Shipfitter and Sheet Metal at the Portsmouth Naval Shipyard, grew up working with HY-80, which is commonly used today, but explained that it represented a big change for welders used to working with Mild Steel in the late 1950s.

“The Albacore welding team had to figure out a lot of things. They were pioneers in HY-80 fabrication,” Arsenault said.

“For example, Mild Steel has a much larger temperature band to work within than does HY-80. Also, with HY-80 welds it takes longer for the hydrogen to migrate out of the metal and this requires longer times between weld inspections, seven days with HY-80 versus one day with Mild Steel.”

The Albacore comes home The Albacore was decommissioned in 1972 and was moved from Philadelphia to its present location in Portsmouth, NH, in 1985.

“This community has a huge sense of pride in the Albacore,” said Patti Violette, Executive Director /Curator.

“The people who worked on this vessel, and their decedents, were behind the effort to create this museum and park, which opens up the story of the Albacore

to the wider world.”

Herrick added, “While the Navy ‘gave’ us the sub, it came with a donation contract that includes many stipulations.

For example, each year the Navy inspects the sub to insure that everything is up to spec. We are responsible for making whatever repairs the Navy dictates and for the associated costs of those repairs.”

Averaging over 32,000 visitors a year, the museum is in an enviable position of being self-supporting from an operations standpoint. Herrick explained, “However, extraordinary repairs have become necessary with time. To this end we have formed the Portsmouth Submarine Memorial Association (PSMA) to focus on fundraising for these expenses.”

The museum is currently working on Phase 3 of the Albacore Preservation/ Restoration Project. Phase 1 consisted of renovating the Albacore’s dry berth basin to eliminate the ship’s hull exposure to the existing corrosive environmental conditions. Phase 2 involved the repair of

SPECIAL FEATURE | ADDITIVE MANUFACTURING

Adopting additive manufacturing As much a mindset change as it is technological

By Linde Gases

C

ompanies putting manufacturing at the heart of their business are under mounting pressure, both from global competition and the rapid rise in technological advancements that are changing the way goods are manufactured.

With mass production having largely shifted to developing economies, Western companies are moving towards lower volume production of high-added value, innovative, customizable and more sustainable products. They also continue to seek out ways to improve cycle times, reduce waste and maximize work flow.

To compete in this new environment, manufacturers have sought new fabrication approaches to support economic low volume production. One such emerging technology is Additive Manufacturing (AM). Capable of producing fully dense components layer by layer from computer aided 3D modeling, the technology removes many of the limitations of manufacturing techniques based on traditional subtractive methods.

AM consists of various technologies to process versatile materials – from laser powder-bed fusion, directed energy deposition (using a laser or an arc), electron beam melting, to binder and material jetting – and once destined primarily for prototyping, AM is now employed increasingly for the development of spare parts, small series production and tooling.

Adoption of AM has seen the greatest uptake in industries where its 42 | gasworld US Edition • January 2020

relatively higher production costs can be outweighed by the advantages AM can deliver, particularly in highly innovative, leading-edge industries such as aerospace, defense, medical and automotive. Such advantages include greater design freedom and customization, removal of tooling requirements, improved product strength and functionality, reduced assembly time for complex components, localized production, rapid time to market, mitigation of wastage, reduced obsolescence, decreased reliance on traditional suppliers, and even the creation of new materials with unique mechanical and behavioral properties.

As a disruptive technology, it challenges the foundations upon which much of

“... the technology removes many of the limitations of manufacturing techniques based on traditional subtractive methods” traditional manufacturing understanding, practices and experience is based. From design, quality inspection and even supply chain operations, AM confronts generally accepted notions of manufacturing for the production engineers involved, presenting considerable needed changes in mindset.

For many, overcoming resistance has as much to do with change management as it does with overcoming the unfamiliar technical landscape.

Linde is a leader in pioneering gas technology to optimize the additive manufacturing process, overcoming the challenge posed by atmospheric impurities in order to give manufacturers optimal printing conditions. Through leveraging its own technologies and expertise in the area, Linde recently embarked on a research project to advance manufacturing techniques of industrial burners using AM. However, its lessons were far from limited to the actual AM process itself, resulting in an appreciation of the mindset adaptation needed to successfully transition from traditional manufacturing to AM. The burners in question Burners are made from multiple metal components typically produced by subtractive manufacturing methods in which the parts are machined from large masses of premium grade brass or steel. Added to this process is milling the many multi-directional holes to be drilled and brazed, the cutting of threads, nozzle tips to be screwed and welding of other connections.

The use of burners is a critical operation for various process industries and they are often tailor-made for the specific application, requiring up to 20 components or more. The burners must also ensure an even, homogeneous gasworld.com/specialfeatures

flame distribution, requiring highly skilled manufacturing.

Such customization and specialist proficiency can make the end-to-end process of manufacture complex, expensive and lengthy.

For the Linde AM research project, the burners in question were Linde’s own LINDOFLAMM® acetylene burners for pre and post-treatment of welded components, though theoretically the process steps and learnings could be applied to other burners for varying applications and industries.

While reduced labor costs, production time and wastage were key goals, it was recognized that the AM process could enable additional, highly valuable functionality to the burners – for example, facilitating a cooling layer to protect the burner in order to reduce thermal stress. However, this is very challenging to incorporate through traditional manufacturing techniques – and for cooling over curved surfaces, almost impossible.

The project The project initially arose out of a goal within Linde to promote AM methods

across its own manufacturing product portfolio. Linde undertook an ideation workshop to understand how it could benefit from the technology – and what adjustments would be needed in order to undertake successful prototyping.

One of the most significant adjustments was the idea of a complete redesign of the burner for production in a printing chamber. While the engineering team undertook basic AM training and had the support of Linde’s AM specialists, a key learning was that there is no replacement for direct experience. Adopting a ‘fail fast and learn’ approach, the team operated a series of learning ‘loops’: component modeling via computer aided design

(CAD); component printing; sub-optimal results; back to the drawing board; redesign; try again.

One of the early challenges – but also an important learning from the project – was that the original component design was not precise enough and showed microgaps in the model, leading to poor contours and issues with porosity, resulting in leakage of the burner.

Through trial and error and further collaboration with the AM team, the engineers learned what specifications and factors needed to be prioritized in AM. Change management While the excitement over AM continues January 2020 • gasworld US Edition | 43

SPECIAL FEATURE | ADDITIVE MANUFACTURING

unabated, on initiating AM production many manufacturers find their early efforts less than optimal. Sometimes it is a lack of understanding of the technology: the wrong AM process or material selected, sub-optimized atmospheric conditions within the print chamber, incorrect positioning or inappropriate post processing treatments. Or that the specific component design was more suited to a conventional technology and not adapted sufficiently to AM capabilities. While there are enormous benefits to be gained from AM, expectations need to be set in terms of the many potential snags and challenges a company may experience to create the perfect part.

As manufacturers begin to adopt AM technology, companies need to consider the human challenges beyond the strategic and technical ones. These can include how to develop know-how within manufacturing engineering teams and, perhaps more fundamentally, how to overcome resistance to this innovative technology.

AM necessitates a change of mindset on the part of those involved. Until very recently, designers and engineers have been taught to think in subtractional terms. In the voice of one key engineer at Linde, “Our university education to learn engineering via subtractive methods needs to be essentially eradicated from our brains. We need to re-educate ourselves in terms of design.”

Engineers now need to take into consideration the limitations of old technical feasibilities and the potential – and also restrictions – of new AMenabled ones. For example, instead of internal geometries of components being created with complex individual parts through intensive assembly processes, engineers can now produce almost all geometries in a single print phase, enabling design of parts according to their function. However, this recalibration in thinking – even among the most experienced and lauded engineers – can take time. As such, it is equally a case of change management as it is about 44 | gasworld US Edition • January 2020

“Engineers need to take into consideration the limitations of old technical feasibilities and the potential – and also restrictions – of new AM-enabled ones” learning new models and approaches to manufacturing engineering. According to one of Linde’s lead engineers, “One of the targets of the project was to make this new way of thinking second nature.”

Conclusion Linde has successfully developed an

additive manufactured prototype of its market-leading LINDOFLAMM burners, with the value-added capability of delivering an excellent cooling layer to burner. Next phases of the project include testing of the new prototype burners with customers to ensure they meet exact requirements and reliability, and then scaled-up production for product launch in 2020.

Implemented properly, AM can encourage manufacturing engineers to think beyond the boundaries of traditional manufacturing methods to reduce the number of production steps, material wastage, inventory held, and the overall parts needed to be manufactured for assembly. But an implementation framework covering both technical education and change management strategies are needed to make it work. gw

ADDITIVE MANUFACTURING: A SPECIALTY GAS SNAPSHOT As a technology, AM has existed for more than 30 years. But, the explosion in its industrial application has intensified in the past five years. According to Linde, it sees the market development at between 25-30% per year with all main geographic regions participating in the uptake of the process, and the usage of gases being equally important in the powder production, AM machine and post treatment processes.

From the very outset of the additive manufacturing process, industrial gases and their enabling technologies play a fundamental role. High pressure argon or nitrogen is used to atomize highalloyed metals into small, uniform spheres of powder particles to create the 'raw' material from which finished parts will be formed. Gases are also vital for

the various laser-based layering processes to 'bind' the powdered metal alloys.Oxygen, and oxygen detection is also used in controlling the chamber environment.

Once a component has been produced, it must go through a final step of cleaning to ensure it is ready for market. Parts that have been printed have some rough surfacing and flashing that require smoothing before they are ready for use, and technology to solve this is integral to the entire AM process. Linde’s CRYOCLEAN® Snow, for example, has been designed specifically for industrial surface finishing and produces dry ice particles on demand for cleaning. Solid dry ice particles are created and shot onto a component surface using compressed air for an effective cleaning process to smooth out edges of a finished piece. gasworld.com/specialfeatures

SPECIAL FEATURE | CRYOGENIC CENTRIFUGAL PUMP SEAL

Who likes a low-down, lousy, leaking pump seal?

Part two: How to extend the life of your cryogenic centrifugal pump seal

By Keith Hall, Applied Cryogenic Technologies (ACT)

L

ast month, in part one of this article, we discussed the first three of five simple, yet critical things operators can do to extend the life of the pump seals on the external cryogenic centrifugal pumps they operate: 1.

Properly prechill the pump before starting it; 2. Before starting the pump and throughout the delivery, build and maintain sufficient net-positive suction head (NPSH)/sub-cool pressures; 3.

Maintain back pressure on the pump throughout the pumping operation.

In this second part and final instalment we will discuss: 4. Never let the pump run dry; 5. Keep the pumping system free of moisture, before some advice from experts and some final thoughts. © CS&P | A sealess pump

46 | gasworld US Edition • January 2020

4. Never let the pump run dry The fastest way to ruin a pump seal is to run a pump dry. An operator should never attempt to start a pump when it is dry, nor even while it is cooling down.

Not even for a quick instant. And a maintenance person should never “bump” a dry pump, ie., to verify rotational direction (such as when you are connecting up the three legs of power on a 440-volt, 3-phase supply and you want to make sure the electric motor driven pump is rotating in the correct direction to make the pump discharge product).

Under any circumstances, before operating, a pump must be cold and the seal lubricated with the cryogenic liquid, or serious damage to the pump seal will instantly occur. Even during normal offload operations, damage to the pump’s seal is caused, for example, when a pump is permitted to run dry at the end of offloading an entire load of product.

If the operator is not paying attention, the pump, running at full speed, will lose prime and cavitate as the supply tank nears empty, leaving the seal dry while rotating at high speed.

Never, ever, under any circumstance run a cryogenic pump warm or dry, not even for a quick instant!

If the operator is paying attention, he will notice the pump discharge pressure gauge needle begin to flicker when the liquid level gauge is showing only

“Before operating, a pump must be cold and the seal lubricated with the cryogenic liquid, or serious damage to the pump seal will instantly occur” a few inches of water column on the differential pressure liquid level gauge.

The operator may choke back the discharge valve, open the forced feed pressure build valve, and slow the pump, and be able to off-load a bit more product. But this is done at the risk of running the pump dry – spinning the pump seal dry at high speed, will cause significant wear and can even destroy the seal. The best course of action for the operator is to note the minimum liquid level at which he or she should stop the pump – and do so.

The operator may simply slow and stop the pumps, or may partially open the recirculation valve while closing the discharge valve, and then slow the pump to a complete stop. Leaving a small heel of product in the transport trailer or bulk storage supply tank serves to help keep the tank cold until it is filled again.

And by so doing the risk of running gasworld.com/specialfeatures

DID YOU KNOW? Did you know that the units of measure for pressure head is “feet of water column” pressure?

One foot water column, 1-inch wide by 1-inch across by 1-foot tall, weighs 0.4334 pounds.

Thus a one-foot tall column of water, no matter its lateral dimensions exerts a downward force of 0.433 pounds per square inch (psi).

The table below shows the respective column heights of water and common cryogens to produce 5 psi.

Regarding the 5-psi sub-cool rule, when converted to head pressure, 5 psi is the same force exerted by a column of water 11.5 feet tall. Since it is less dense than water, a taller column of nitrogen, over 14-feet tall, is required to produce the same 5 psi force an 11.5-foot tall column of water produces. Argon is denser than water and only requires a column 8.6 feet tall to produce the same 5 psi force. At 3.54 pounds per gallon, LNG is very light and would require a column over 27-feet tall to produce the same 5 psi!

For your reference a table showing the densities of various common cryogens compared to water is provided below.

THE 5 PSI RULE FEET HEAD PRESSURE EQIVALENTS

COMMON PRODUCT DENSITIES

Pump manufacturers provide pump curves for their various model pumps.

Unique head pressure versus flow rate curves are generated for each cryogen at the pump speed necessary to produce the required discharge pressure range and corresponding flow rate range; and given an assumed pump suction pressure (tank pressure is additive to the pump’s discharge pressure capability). From the table below, you gain an understanding that a pump used to discharge different density cryogens at the same head pressure will product vastly different PSI pressure values.

500-feet of head pressure when pumping water results is almost 217 psi.

The pump discharge pressure is only 91.9 psi when pumping less dense LNG. In contrast, 500-feet head pressure of argon equals 302 psi!

the pump dry is eliminated. Consistently waiting for the pump to lose prime when the supply tank empties before shutting down the pump takes significant life from the seal.

5. Keep the pumping system free of moisture Ice crystals do great damage to pump seals. All cryogenic tanks and piping circuits, including the pump recirculation and discharge circuits must be kept dry. A dewpoint of -40F/C is recommended (-40F & C is the same temperature). Guard again the entrance of moisture into the pump piping circuit.

When you cool down the pump and when you are pumping, frost forms on the outside of the pump and all associated cold piping.

After a delivery operation, as the piping warms the frost melts into water.

It is very important to install the caps back over the fill hose connections immediately upon removal of the hose.

Avoid letting frost form inside piping circuits. The least obvious, but perhaps the most frequent means for the ingress of moisture into piping circuits occurs when an operator leaves the purge/bleed valve open, for example, when venting down and draining the discharge hose.

Just as frost has formed on the outside of the hose and piping, once exposed to the atmosphere, humid air enters the circuit and frost forms inside the piping during the first few minutes after the off-load operation. As the piping warms, like the external frost, the frost that was formed on the internal piping walls melts into water.

And then when the Purge/Bleed valve is finally closed, the moisture is trapped inside. For this reason, bleed valves must be closed as soon as all liquid and pressure have been purged from the circuit.

the end of a delivery, and vent and drain the circuit. Note that these circuits are protected with thermal line reliefs which will prevent over-pressurization of the piping.

Additionally, an understanding of how this internal moisture issue occurs illustrates the importance of a thorough purge of not only the piping, but of the dispense hose, before commencing the next delivery operation. When you purge the hose before a fill, you are not just purging air or debris from the hose and discharge piping connection circuit, but also any moisture.

Ice crystals do great damage to pump seals. Guard again the entrance of moisture into the pump piping circuit.

For many permanent ground-mounted installations, a slight positive pressure dry nitrogen gas purge is applied to the pump seal before the pump cool down sequence is initiated. And the slight purge remains on the seal throughout the off-load operation, and as the pump 48 | gasworld US Edition • January 2020

attentive operator control.”

Dilling states that during initial installation of the pump, “the pump needs to be cooled down with liquid before completely tightening the mounts and flanges to avoid piping strain which could cock the seal and cause a premature leak.”

Although the pumps have flexible hose vibration dampener sections before the inlet (suction) and after the discharge warms up.

Advice from the experts Finally, Dilling concludes, “The operator needs to keep the pump on the Shane Dilling, with Cryogenic Industries operating curve to avoid cavitation abuse Houston, a Nikkiso ACD pump service company, says there are several factors that which will damage the pump’s seal.”

Sean Hardy, Sales Manager for contribute to extending pump seal life, but in his opinion the most critical are “proper Cryostar USA, points out that “Across our industry, it is widely recognized that pump installation, religiously following mechanical seals represent the largest a thorough cool down procedure, and gasworld.com/specialfeatures

“When any of the installation and operational guidelines are relaxed or omitted, premature wear and damage occurs to the mechanical seal” investment for pump maintenance – in addition to the inconvenience caused due to seal failures.”

Hardy also laments that “when pump seals fail prematurely due to incorrect operation, an inaccurate reflection is cast on the reliability and reputation of our equipment. For this reason, we strongly support the good practices highlighted in this article.”

Finally, Brannon K. Baskin, Director of Operations for CS&P Technologies agrees that, “Strictly adhering to the industry accepted practices outlined in this article will ensure maximum service life of your cryogenic pump. When any of the installation and operational guidelines are relaxed or omitted, premature wear and damage occurs to the mechanical seal. Continued operation of a cryogenic centrifugal pump with a leaking seal results in accelerated mechanical damage to the pump. Consequently, the customer incurs a repair cost that is triple to that of a standard repair.”

Note, ACD and Cryostar also offer seal-less pumps that are submerged in the cryogenic tank or vacuum-jacketed sump.

These pumps are expected to last up to ten times longer than the seal on an external centrifugal pump. But not all applications lend themselves to submerged pumps.

CS&P Technologies manufactures patented seal-less magnetic drive cryogenic centrifugal external pumps that eliminate the need for the mechanical seal and feature a pump service life of five times that of conventional pumps.

Final thoughts A Pump Cool Down Timer, which locks out the pump, preventing it from being started before it has cooled down for the manufacturer’s prescribed time period, is a strongly recommended feature to have with each cryogenic pump.

It may also be worth your time to investigate computerized pump monitoring and control systems which not only assist the operator and perform such functions as auto-stopping when filling certain liquid cylinders and minibulk tanks, but which also monitor the pump to protect it.

Such systems monitor key pump parameters, and take action when needed, to protect the pump. Such parameters include controlling proper pump cool down; controlling the 5-psi NPSH/Sub-Cool pressure; monitoring differential pressure to detect the on-set of cavitation; detecting high and low flow

rates; and detecting high and low pump discharge pressures conditions; etc.

Making deliveries to fill mini-bulk tanks and liquid cylinders using an externally mounted cryogenic centrifugal pump is perhaps the worst-case service environment for such a pump.

Instead of being cooled down once and then off-loading an entire load (a bulk delivery, for example), these systems are cooled down and make deliveries at one stop, then the pump is shut down and warms back up as the bobtail or trailer travels to the next customer, then the pump is cooled down again and the delivery process is repeated many times a day.

With trained, conscientious operators, and using computer-controlled systems, the author knows of multiple pump seals that have lasted over seven years in minibulk service.

However, a competent operator, trained with a basic understanding of cryogenic principles and the rules described in this article, can do what the computer does... and probably much more.

One important asset the operator has that a computer does not, is ears – to listen to the pump to make sure it “sounds” happy. And if the pump sounds happy the boss will sound happy too! gw

In Colorado, the booming legalized cannabis industry is a big driver for CO2 and nitrogen, even for companies outside the state. Marijuana legalization revenue now accounts for roughly 3% of the state’s $30bn budget, and in June last year the state announced that it surpassed $1bn in total cannabis-related revenue. Also in June, it was reported Colorado had nearly 3,000 licensed marijuana businesses and just over 41,000 people working in the industry.

Fort Collins, Colorado-based Green CO2 Systems supplies, installs, and maintains CO2, nitrogen, blended gas, and equipment systems to restaurants, bars, swimming pools, indoor cultivation facilities, and convenience stores. Green CO2 serves five primary markets: bars and restaurants, microbreweries, indoor cannabis cultivation facilities, convenience stores, and commercial swimming pools.

Green CO2 Systems’ safety and storage solutions also work with most cannabis extraction technology and can provide extractors with a reliable CO2 source and safe, compliant working environment.

Mitsubishi Hitachi Power Systems and Magnum Development have announced plans for the ‘world’s largest renewable energy storage project’, to be located

in Utah. The Advanced Clean Energy Storage initiative will develop 1,000 megawatts of completely clean energy storage for technologies and strategies in the quest to decarbonize the power grid of the Western US. The consortium plans to hold hydrogen or compressed air in a huge salt cavern in central Utah, which reportedly is roughly one mile deep and three miles across. With five salt caverns already in operation for liquid fuels storage, Utah-based Magnum is continuing to develop Compressed Air Energy Storage and renewable hydrogen storage options.

COMPANY PROFILE | WELDPRO

WeldPro Welding equipment research and development, production and sales service

D

eveloped and wholly owned by Linlong Limited, Minnesota-based WeldPro holds its focus on the US light industrial welding products market.

Launched in February 2017 as a US brand of welding equipment, WeldPro set out with an aim to complement the distribution of the “private label” products that the company provides in the US. Exclusive to the US, WeldPro’s products are developed, delivered and supported by a team of professionals who are experts in the needs of customers. WeldPro’s professionals work alongside customers to deliver productions and solutions for DIY, ranch and farm, construction and the light industrial markets.

Linlong Limited holds a history spanning more than 15 years and employs more than 300 individuals globally. Within its first ten years of business Linlong achieved strategic cooperation with customers globally, with demand coming from the US, Australia, South Africa, Russia, and more.

It was this increased demand from worldwide clients that meant Linlong had to expand and create new business ventures, such as WeldPro for its US customer base. Although still in its infancy as a standalone brand, WeldPro has already gained a significant foothold in the US. Products The company is currently focused on the “light industrial” welding equipment market (under 250 amps). Serving that market, the company has introduced multi-voltage welding equipment and plasma cutting equipment that accepts both 110v and 220v single phase input.

The company is focused on inverter technology in four welding applications:

• SMAW (MMA) – offering four machines for 120 amps to 200 amps • MAW (MIG) – offering three machines from 100 amps to 200 amps • GTAW (TIG) – offering a 200 amp ACDC machine which are well suited for Lift Arc TIG • PLASMA – offering two cutting machines at 40 amps and 60 amps Increasing the company’s product recognition, WeldPro has attended multiple trade shows throughout the year. The company was present at FABTECH Mexico, GAWDA Regional, GAWDA National, and most recently FABTECH 2019 in Chicago where they offered live welding demonstrations.

Future Even in its short time as a standalone company, WeldPro has recognized a need for expansion in order to both quickly and efficiently serve its customers. To encourage and serve

company growth, WeldPro purchased a large plot of land in Wenling City, China, for a new facility in May 2018. A ground-breaking ceremony took place in December 2018 with completion expected in the second quarter of 2021.

The company’s new and modern manufacturing facility will allow for much faster response times to market changes. The “time to market”, generally described as the time from the moment an opportunity is recognized to having products on the shelves and available will be compressed from months to weeks and in some cases days.

Speaking to gasworld, during the FABTECH Chicago event, WeldPro said, “The company recognizes that welding has been, is, and will likely remain the most efficient method for joining metals. And though this metal joining technology is a likely constant, the market trends, manufacturing efficiencies, logistics, communications technologies and business practices can change at dizzying speeds.” gw gasworld.com/specialfeatures
