The paper discusses the development of sealing technology within the organisation with particular emphasis on the gasket manufactured by profiled winding wire. This will be referred to as a PWG.

The paper is a continuation of the paper presented in Paris PVP2013-97050 and follow up in PVP2014-28948. It discusses further laboratory testing and briefly describes 4 related field service case studies.

The paper details tests which include: Thermal cycle, sealing performance, compression and recovery testing carried out in both laboratory and field conditions. The 4 related studies are based around the use on large flanges, the use in oxygen rich environment, the use in a thermal cyclic environment and on problematic flange corrosion.
