Densoclad™ Protection on London Docklands Gas Line
|Contractor||Morrison Utility Services PLC|
|Products||Densoclad 70™ Tape|
National Grid diverted 0.5 km of 450 mm gas line in London’s former dockland, which is part of the Galleons Reach Dockland Development being carried out by prime contractor, Morrison Utility Services PLC.
For protection of all bends, joints and couplings in the gas line, National Grid chose a Densoclad 70™ Tape system. Denso Profiling Mastic™ was first applied where required to give an even contour on fittings to ensure rapid and effective application of the subsequent Densoclad 70 Tape. National Grid have specified Densoclad 70 Tape because it meets their protection requirements including compatibility with the cathodic protection system on the gas line.
Densoclad Tapes consist of a thick polymer bitumen adhesive laminated to a tough plasticised PVC backing. These cold-applied tapes are designed for the long-term protection of buried or immersed fittings.
