Trelleborg’s offshore operation has engineered a new insulation cover that not only withstands extremely cold temperatures at subsea depths but also, with the combination of a silicone liner, the extreme temperatures of hot hydrocarbons. The insulation cover achieves the highest temperatures yet accomplished and in addition, is significantly lighter than steel covers; not molded directly to the pipe the cover gives easy access to critical parts of the flow stream.
Ben Wait, Customer Group Manager for Trelleborg’s offshore operation, says: “The new insulation covers are made from a combination of our trusted insulation systems including silicone Vikotherm™ S1 and polyurethane Vikotherm™ P7. They utilize the properties of cast systems which are poured in a liquid form and solidify to create the finished ‘jacket’, unique to the application.
“We’ve taken our proven knowledge in designing bespoke insulation systems and combined a silicone inner layer to withstand the high temperatures of hot hydrocarbons. The polyurethane outer layer is lighter in weight than traditional steel, to produce the ideal solution.”
