In January 2016, Mark Tool and Elite Elastomers entered into a joint venture focused on the research, development, and end-use application for complete, elastomeric, subsea high-temperature thermal insulation systems that could be installed via three methods: J-Lay, S-Lay, and Reel-Lay. The newly formed company has been named MTE Engineered Materials. The chosen name represents the combined strengths of both Mark Tool and Elite Elastomers. MTE Engineered Materials is proud to present to you the latest groundbreaking technology in subsea thermal insulation: ThermoTRON®.

ThermoTRON 350®

High-temperature wet insulation system intended for use in splash zone protection of risers, hull piping and subsea jumpers, with an internal operating temperature of up to 350°F.

ThermoTRON XT®

High-temperature wet insulation system intended for subsea flow lines and tiebacks, with an internal operating temperature exceeding 350°F.

Application

ThermoTRON 350® is a high-temperature wet insulation system intended use for insulation and splashzone protection of risers, hull piping, and insulation for subsea flow-line, with an internal temperature up to 350 degrees Fahrenheit.
 
This product consists of three layers, a corrosion resistant layer, a bonding agent layer, and a high temperature high density elastomer layer.
 
ThermoTRON 350™ Systems has 60 years of experience built into its technology. The system was designed to perform in extreme harsh environments. It is robust and very flexible and will extend protection for the lifespan of subsea installations. The three-layer coating system provides corrosion protection and excellent thermal insulation properties.
 
The system is seawater, impact and creep resistant. It will also provide excellent resistance to weathering, fungus, and marine life.

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

Layers

ThermoTRON 350® consists of three layers that are vulcanized to the steel pipe surface.
 
  • 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.
  • The second layer consists of a bonding agent that works as a bonding layer between the ThermoTRON 350™ top coat and the first layer of corrosion coating.
  • 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.
