The Follow Up Development and on the Usage of the Profiled Wire Gasket

Abstract

The paper discusses the development of sealing technology within the organization 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 papers in PVP2014-28948 and in PVP2018-84067. It discusses further laboratory testing and briefly describes two related field service case studies. The paper details tests which include: oxidation testing of graphite, compression and recovery testing, chemical resistance testing of fillers in Sulphuric Acid service. The two related studies are based around the use in a Western Canadian refinery on a hot vapour exchanger and on a Fluidised Catalytic Cracker problematic flange.
