SUCCESS STORY: Tampere Energy

Teknikum’s Ceramic hose enables maintenance-free process in the power plant’s boiler sand transfer

Heat production at Tampere’s Naistenlahti power plant is intensified by boiler sand, which is consumed in boilers by tons every week. The sand is transferred to the power plant’s silo with the help of Teknikum’s hose innovation, along a ceramic material transfer hose developed and manufactured in Sastamala Finland.

A tank truck reverses at the power plant’s yard and the driver attaches a hose that transfers huge masses of sand to the power plant’s silo via a connector. Soon 16 tons of boiler sand erupt from the tank truck as strong impulses to the power plant’s furnace. The rubber hose must withstand relentless wear as the sand shakes with force in the bends of the hose. The transfer of boiler sand is made possible by the result of hundreds of hours and several years of product development: a rubber hose with a ceramic-coated inner surface.

Mr. Jari Perälä, a maintenance engineer of Tampereen Energia’s Naistenlahti power plant, follows the transfer of sand from the tank truck with confidence.

Nordic top product also for export

Teknikum’s Product Manager Mr. Jarkko Kalliomäki is pleased that long-term development work has opened up new business opportunities and strengthened Teknikum’s future.

– We have supplied hoses to the energy industry, the forest and paper industry and especially to the mining industry, but also to the steel industry. The latest customer segment is waste treatment and recycling plants, Kalliomäki describes the expanded customer base.

Teknikum has been manufacturing material transfer hoses for the demanding industries for decades and has customers in the Nordics and around Europe.

– The ceramic hose combines the great features of a rubber hose, such as easy installation, flexibility, easy adaptability of transmission lines and damping properties, Mr. Kalliomäki multiplies the great features of the product.

– We are able to manufacture almost all of our hose products with a ceramic inner surface. From small material transfer hoses to large heavy hoses up to a meter in diameter.

"The ceramic inner lining lasts up to years where the previous metal pipe was worn out in a few months.

The puncture-proof rubber-ceramic hose increases occupational safety, protects the environment and reduces the risk of production delays. We manufacture industrial hoses in all size classes, for demanding applications from the transfer of soil materials to acids and oils.

– Markku Haaranen, Teknikum

The hose is suitable for the transfer of highly abrasive materials, such as mining slurry, lime powder, coal, quartz sand and granules, in areas where it is desired to reduce and avoid continuous service interruptions caused by hose replacement. The market is global.

Sustainable development and continuous improvement

Teknikum’s sales manager Mr. Markku Haaranen remembers well how the cooperation with the Naistenlahti power plant, owned by Tampereen Energia, started few years ago.

– Our local dealer was able to advise the power plant’s maintenance manager to contact us with the need for a customer-specific solution. Together with the dealer and customer, we got to the site and learned the challenges of the plant’s material transfer. When the original metal pipe was upgraded to a extremely durable Teknikum GRANIT Ceramic hose, the reliabil-

ity and efficiency of the customer’s production process improved significantly. The ceramic inner lining lasts for years where the previous metal was worn out in a few months, Haaranen recalls.

Haaranen is rightly satisfied with the solution.

– Many have tried to copy the structure of our innovative hose, but so far only Teknikum knows how to produce a high-quality ceramic lining on a curved surface. As a Nordic manufacturer, we want to spread the useful good news of our solution to European industry.

The puncture-proof rubber-ceramic hose increases occupational safety, protects the environment and reduces the risk of production delays. We manufacture industrial hoses in all size classes, for demanding applications from the transfer of soil materials to acids and oils.

Teknikum also offers couplings and special hose solutions with fast delivery from factory stock.

The ceramic lining on the inner surface of the rubber hose withstands the transfer of abrasive materials such as sand and sharp stones while remaining flexible and easy-to-use.

Teknikum® abrasive working hoses - easy to handle, durable in use.

TEKNIKUM® multi-purpose industrial working hoses can be utilized in transferring dry or wet, finegrained and irregular, or sharp and hard objects and substances. In addition to high resistance to wear, the hoses are designed to withstand various demanding processes, such as industrial vacuuming and suction applications.

Typical targets for industrial vacuuming and blowing are the emptying and filling of tanks, silos and warehouses in, for example, power plants, the food industry and the process industry. As a common denominator, the suction and blow hoses of the applications have high wear resistance and easy handling.

Teknikum® CARBON hoses

Teknikum CARBON™ working hose family with corrugated or smooth cover are extremely flexible and durable abrasive material handling hoses. The hoses are designed for industrial vacuum systems and are also suitable for a wide range of industrial suction applications.

The lightness of the best work hose on the market does not come at the expense of wear resistance: with a new inner surface, we significantly improve the tear strength – and offer even slightly less abrasion wear. According to our tests, the tear strength of the new inner surface increased by 40 »90 N / mm!

One of the basic features of Teknikum’s CARBON hose range is that we offer an antistatic version. This means that the hose has a black natural rubber inner surface, which guarantees excellent durability combined with electrical conductivity and better safety. The hoses are available also with spiral-free cuffs.

Our products are manufactured with special Finnish expertise and have been awarded with the “Made in Finland” Key Flag symbol.

Teknikum® BLAST-TEK hoses

This hose series offer multi-functional blasting hoses for both dry and wet materials. A great choice for work applications such as sand and grit blasting, concrete pumping or transferring granulates.

Teknikum® BLAST-TEK hose’s CERAMIC version enables very long life due its ceramic inner lining. The life cycle of the hose is significantly longer and thus work interruptions and continuous hose purchases can be avoided. Teknikum BLAST-TEK® exceeds EN ISO 3861:2008 (Rubber hoses for sand and grit blasting) technical requirements as well as fits to commonly used sand blasting hose couplings.

How to select a hose?

In most situations it is easy choose the right industrial hose because a use application or some other feature (e.g. transferred material) defines the hose and a standard guides to the right solution.

In addition to standard hose products, Teknikum manufactures industrial hoses according to customer-specific dimensions and requirements. When designing a suitable material handling solution, customers can choose the hose structure, rubber grade, diameter, length and connectors.

Our specialty is wear and chemical resistance in extreme conditions.

When no suitable hose is available in standard product range or the use application is special, several hose properties must be considered.

INSTALLATION

For the overvoltage terminal of the transformer:

The guard is attached to the upper flange of the overvoltage penetration of the transformer and is tightened firmly with the included cable tie. The excess part of the bundle is cut off.

For surge protector (ABB MWK):

The protector can also be attached to ABB MWK type surge protectors.

In this case, two opposite overhanging parts are cut from the bird guard above the fastening groove. The cut parts are turned inwards on the flange of the surge protector. The protection is tightened with the help of the four protrusions on the edge of the flange and the bundle tie, and the cut parts ensure that blows from above do not detach the bird protection from the surge protector.

Note: Do not cut the projections with the fastening loops for the cable tie.
