Durlon® Spiral Wound Gaskets are manufactured according to ASME B16.20 standards and the Quality Assurance complies with API Specifications Q1 and ISO 9001:2008
Durlon® Spiral Wound Gaskets (SWG) are made with an alternating combination of a preformed engineered metal strip and a more compressible filler material which creates an excellent seal when compressed. The engineered shape of the metal strip acts as a spring under load, resulting in a very resilient seal under varying conditions.
The strip metallurgy and filler material can be selected to seal a wide range of applications. All Durlon® SWG styles have been engineered to precise manufacturing tolerances that allow for lower stress (bolt load) sealing compared to conventional spiral wound gaskets.
All Durlon® SWG are manufactured according to ASME B16.20 standards. Quality Assurance complies to API Specification Q1 and ISO 9001:2000.
There are three styles of standard Durlon® Spiral Wound Gaskets:
