New insulation coating helps maintain product flow

摘要

Awarded by Subsea 7 in July 2009, Tata Steel's scope of work was to supply the coating of the pipe for the Total E&P Netherlands BVs K5CU project. The work was for approximately 15 km (about 6 mi) of a 10-in. (25-cm) natural gas pipeline and the same quantity for a 3-in. (8-cm) di-ethylene glycol line. The majority of the pipeline was coated with a standard three-layer polypropylene coating, but 530 m (1,738 ft) needed an insulation coating with a U value of <6 W/m2K in the unburied state.
