Subsea Insulation
FLOW-THERMTM is a highly efficient and cost-effective subsea insulation with excellent compressive resistance. It has high strength, great adhesion, and exhibits toughness when applied on subsea flowlines and risers, field joints, and equipment, such as jumpers, pipeline end terminations (PLETs), pipeline end manifolds (PLEMs), inline structures, shrouds, doghouses, and any moldable structures for deep and ultra-deepwater applications.
FLOW-THERM subsea insulation is available in three different materials: silicone (Si) rubber, polymer alloy (RS 3604), and glass syntactic polyurethane (GSPU), suitable for various operating conditions and applications.
