Spiral wound gaskets

Listing ID #4220331

Spiral Wound Gaskets are special semi-metallic gaskets of great resilience; therefore they are very suitable for applications featuring heavy operating conditions. SWG manufactured by spirally winding a V-shaped metal strip and a strip of non-metallic filler material, The metal strip holds the filler, providing the gasket with mechanical resistance and resilience. SWG can be reinforced by an outer centering ring and/or inner retaining ring, The outer centering ring controls the compression and holds the gasket centrally within the bolt circle, The inner retaining ring increases the axial rigidity and resilience of the gasket and acts as a Heat and Corrosion barrier eliminating turbulence between the gasket Inner diameter and the flange bore so avoiding erosion of the flange faces.
