Common applications of this product include pipeline coatings, platform structural members (legs and diagonals), conventional risers, pipelines pulled through J-tubes, conductors, and the lining of riser clamps. Mark Tool has coated offshore platforms with SplashTRON® for two decades.
The tough, long-lasting elastomer is applied to structural members exposed to the splash zone during fabrication. It provides complete protection against the erosive action of abrasive-laden seawater, the harsh attack of ozone and ultraviolet rays, incidental impact from boats and floating debris, and the effect of sea life which builds upon all offshore installations.
An important feature of SplashTRON® in pipeline coating application is the fact that it is completely and permanently bonded to the metal surface, and because it is flexible, it won’t crack or disbond as the members bend, expand, and contract. This product can be expected to protect against corrosion for the life of the platform. SplashTRON® has proven its effectiveness in the Gulf of Mexico and other offshore areas around the world for more than 30 years. It is used by the leading producers of oil and gas, and most transmission companies.
Thermal Insulation
TYPICAL APPLICATIONS FOR THERMOTRON 350®:
• Insulation System for Flow-lines
• Insulation System for Production Risers
• Insulation System for Hull piping
• Insulation System for Tie-backs
• Insulation System for Spool
THERMOTRON® 350 THREE-LAYER PROTECTION SYSTEM
1. The first layer is a corrosion coating that provides the pipe surface (the pipe is first steel grit blasted) with a film that is highly resistant to chemical attack and to cathodic disbondment.
2. The second layer consists of a bonding agent that works as a bonding layer between the top coat and the first layer of corrosion coating.
3. The third layer consists of extruded ThermoTRON 350™ 1” thick depending on the service conditions (the thickness could vary). The function of the third layer is to provide the system with excellent thermal insulation properties and both anticorrosive and mechanical protection.
SUBTRON®
ADVANCED DEEPWATER PROTECTION FOR TITANIUM STRESS JOINTS
SubTRON® is a high-performance bromobutyl rubber (BBR) protection system engineered specifically for titanium stress joints (TSJs) used in deepwater offshore risers and subsea production systems. Developed for some of the world’s most demanding offshore environments, SubTRON provides a durable environmental barrier that protects critical titanium components against seawater exposure, extreme hydrostatic pressure, and hydrogen ingress throughout the service life of the field.
Titanium is widely selected for stress joints because of its exceptional strength-toweight ratio and outstanding corrosion resistance. However, in deepwater subsea systems utilizing cathodic protection, atomic hydrogen can be generated at the metal surface. Under certain conditions, hydrogen may diffuse into the titanium and form titanium hydrides, reducing ductility and fracture toughness and potentially affecting the long-term structural integrity of highly stressed components.
SubTRON addresses this challenge by utilizing a factory-vulcanized bromobutyl rubber barrier that is chemically bonded to the titanium surface. Bromobutyl rubber exhibits exceptionally low permeability to gases, moisture, and hydrogen-containing species, significantly reducing the transport of seawater and dissolved gases to the titanium interface. Compared with conventional neoprene-based protection systems, SubTRON provides superior barrier performance for applications where long-term environmental isolation is critical.

VULCANIZED RUBBER CLAMPS
Mark Tool & Rubber has been vulcanizing riser clamps for the oil & gas industry with SplashTRON® for over 40 years. Vulcanization refers to a specific curing process of a rubber product involving high heat and the addition of sulfur or other equivalent curatives. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon to carbon bonds.
CUSTOMIZABLE, COSTEFFECTIVE & DURABLE
The end result is that the springy rubber molecules become crosslinked to a greater or lesser extent. This makes the bulk material harder, much more durable, and also more resistant to chemical attack. Mark Tool & Rubber also can fabricate riser clamps to customer specification or drawings.

UREGUARD PIPE SUPPORTS
OUR PIPELINE SUPPROTS CAN BE REMOVED WITHOUT PICKING THE PIPELINE UP FOR MAINTENANCE OR PAINTING
The corrosion-related cost to the transmission pipeline industry is approximately $5.4 to $8.6 billion annually. One of the most common corrosion problems on a pipeline is where pipe supports interface with the pipe.
Mark Tool & Rubber Co, Inc. working together with pipe line Corrosion Technician has come up with the ultimate design for Pipeline Support System.
Our UreGuard Pipeline Supports are made of a durable castable polyurethane 90D durometer and can be adjusted to multiple sizes of pipe. The biggest advantage of our system is that it can be removed from the pipeline without picking the pipeline up for maintenance painting.
URETHANE PIPE SPACERS
PREVENT A SLOW DOWN IN OPERATIONS WITH A MATERIAL THAT CAN STAND THE TEST OF TIME
Polyurethane is the ultimate workhorse.
Whether used as a spray, foam, a flexible, spongey elastomer, or a solid that is as hard and tough (almost) as any diamond, polyurethane’s versatility means it can be molded into components of any size, shape, and hardness.
The oil and gas industry demands a lot from its tools, including customization in the design-build phase and ongoing reliability in the field. Polyurethane parts stand up to any punishment thrown at them, and new ones can be quickly machined as needs change or evolve.
Urethane pipe spacers and casing spacers are placed around pipelines in underground and subsea applications. They make a perfect case study to illustrate what we’re talking about.
Put simply, these humble components keep pipes carrying oil and gas a specific distance apart. Outside of the oil and gas industry, they’re used to hold water, sewage, and electric pipelines in place. They also prevent damage to pipes and casing as they’re being stored in pipe yards or transported to the field. Pipelines protected by casing also use spacers to separate and isolate the carrier pipeline from the casing.
Pipes maybe made of steel, concrete, PVC, polyethylene, or plastic. Pipe spacers can be formed from various types of rubber and plastics, including polyurethane, polyethylene, PVC, carbon steel, and stainless steel. Along with the product the pipe carries and the environment surrounding the pipeline, the pipe’s material will determine what kind of spacers are appropriate.
Polyurethane, however, is our material of choice for the harsh environment of the oil and gas industry. When other materials often crack, break, tear, swell, abrade, and deteriorate, polyurethane can stand the test of time. Metallic and plastic spacers are vulnerable to problems that can slow down operations and, ultimately, lose revenue.
Polyurethane pipe spacers can be easily formed to your precise specifications because they are castable. Complicated design and engineering are usually required to adjust metallic pipe spacers, while urethane-based materials are easily formed into exact dimensions from simple silicone molds.
UREGUARD TOWLINE PROTECTORS
OUR UREGUARD TOWLINE PROTECTORS ARE CUSTOM MADE TO FIT ANY SIZE CABLE OR ROPE
Commercial towing vessels depend on towlines, also known as hawsers. They also depend on Mark Tool to keep those lines protected from chafing and from the harmful effects of seawater.
Whether used for offshore oil and gas operations, dead-ship towing or salvage, the towing hawser is the key element in the tugtow connection.
Hawsers used for conventional tugs are essentially a thick cable of wire rope. The condition of these lines is critical; they must be inspected on a regular basis, lubricated regularly, and shielded against excessive wear.
Towline Protection
UreGuard towline protectors are made of two halves bolted together with high-grade, noncorrosive bolts for easy installation. The tapered ends of the Mark Tool towline protectors act as bearings to prevent premature line parting and lost tows.
A tug master should always know the condition of his tug, towing hooks, and fittings. Steel towlines and ropes should have a safe working load at least two to three times the bollard pull of the tug. Ancillary equipment, including wire towage protectors and thimbles, should be regularly inspected.
Regular towline inspection means looking for signs of ultraviolet or chemical degradation, worn or fused strands, overstretched sections, and kinking.
It also means having the sleeves and protectors you need for your main and secondary towlines. Mark Tool towline protectors are available in lengths of 5-10 feet or can be manufactured to your specifications. We’ll be happy to custom-build them to fit any size cable or rope.
