Trelleborg Debuts Thermal Insulation Portfolio

Posted by Irina Tabakina

Trelleborg’s offshore operation announced it has consolidated its range of high performance thermal insulation materials to house them all under one brand – Vikotherm, which was presented last month at OTC in Houston. “As subsea environments become increasingly more demanding; going deeper and further than ever before, temperatures and hydrostatic pressure become much greater,” said Ben Wait, customer group manager with Trelleborg Offshore and Construction. “As a result, the demand for more sophisticated products which can cope with these harsher environments is growing. And this is certainly the case with our thermal insulation materials; so we’ve taken the strategic decision to group all of our solutions together to allow for easier product selection and ensure that all customer needs can be met in one place.”
All solutions in the Vikotherm range are designed for maintained flow rates, optimum productivity, reduced costs and protection against wax and hydrate formations.
Two of the featured products in the portfolio include the R2 and S1 materials. Vikotherm R2consists of a three-layer coating system which provides protection against corrosion and hydrogen induced stress cracking (HISC). Similarly, its seawater, impact and creep resistance means that it offers thermal insulation properties. The material is suitable for jumpers and spool pieces, tie in spools, manifolds, subsea trees, risers and flowlines, joints, insulation covers and many more applications.
With the capability to be applied in any geographic location, this material can operate in temperatures ranging from -49°C to +155°C /-56°F to +311°F, and depths as low as 3,000+m / 9,843+ft. In addition, being almost entirely maintenance and absorption free, the R2 allows for undisturbed, optimal high pressure and temperature flow performance.
In addition, the Vikotherm S1 is based on non-syntactic silicone technology, and the manufacturer maintains that it is ideal for risers and flow lines, subsea trees, pipeline end manifolds, pipeline end terminations and more, with operating temperatures of -40°C to +135°C/-40°F to +275°F and depths of 3,000+m/9,843+ft. Other solutions in the Vikotherm range include epoxy syntactic foam, E1 and E2; non-mercury catalyzed polyurethane, P7; syntactic polypropylene tape, PT and non-mercury syntactic polyurethane, G3.
