Pre-Insulated Pipe System
The FLOW-THERM™ system is the Standard Series consisting of either glass syntactic polyurethane (GSPU) or silicone (Si) insulation is a highly efficient and cost-effective thermal insulation with excellent compressive resistance when used on subsea flowlines, risers, field joints, and equipment, including jumpers, pipeline end terminations (PLETs), pipeline end manifolds (PLEMs), inline structures, shrouds, and doghouses for deep and ultra-deepwater requirements.
Including AUTO-THERM (GSPU), Silicone
​GSPU for temperatures up to 226° F (108° C)
​
SI for higher temperatures up to 320° F (160° C)
