Hyperlast "Syntactic" polyurethane
Hyperlast "Syntactic" polyurethaneKeywords: Polyurethane, Coatings, Subsea, Insulation
Hyperlast "Syntactic" polyurethane coatings provide both physical and thermal insulation to subsea oil and gas flowlines and risers, field joints, manifolds and spool pieces, reducing the risks associated with wax and hydrate formation, and guaranteeing arrival temperatures at the platform (Plate 3).
The inclusion of glass spheres with the polyurethane allows the coating to withstand the pressures associated with subsea depths of 3,000m (10,000ft). Simulated tests carried out by Heriot-Watt University and Hyperlast Pipeline Engineers make certain that Hyperlast "Syntactic" DW-512/300 thermal insulation and strength capacities are achieved.

polyurethane coating for subsea pipe
Tests show that, with internal pipe temperatures at up to 100°C (212°F), there is:
- •
no change in thermal conductivity, thereby ensuring consistent insulation properties;
- •
no change in coating thickness due to compression by hydrostatic pressure;
- •
minimum water absorption over a 20-year period.
Hyperlast "Syntactic" polyurethane is able to withstand the rigours of laying by reel barge, "S" or "J" lay, and provides corrosion protection, impact strength, durability and flexibility, plus excellent adhesion to the raw pipe.
Available in various hardness ranges, and with a low processing temperature, Hyperlast "Syntactic" DW-512 may be sprayed, moulded or rotationally cast.
