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.
