Hyperlast Limited recently introduced the latest innovation in deep sea polyurethane technology - sub-sea thermal insulation and protection for deepwater, high-temperature pipelines (Plate 2).
Plate 2 The DW-512 pipeline coating from Hyperlast combines physical protection with thermal insulation
The DW-512 is a new development on the original "Hyperlast"® Syntactic, which, since 1984, has found widespread approval from the international offshore industry and is used extensively throughout international waters by many of the industry's leading names including Amerada Hess, BP Amoco, Conoco, Exxon, Mobil, Shell, Statoil, Total and Texaco.
The company reports that its "Hyperlast" Syntactic is a standalone, single layer coating that combines physical protection with thermal insulation. Its cellular composition, based on the use of evenly distributed microspheres, provides long-lasting protection and reliable performance in deepwater environments.
DW-512 technology is based on a matrix of microspheres that are said to be incompressible at depths from 600m to in excess of 2,000m, and its insulation properties do not succumb to fluctuation. There is also said to be no restriction on the thickness of material used and it can be applied using the same method as the current 512 material, either by moulding or by rotational casting.
