Style WR 304SS w/Flex Graphite Filler 150lb Spiral Wound Gasket
|
Style WR gaskets consist of a winding with a solid metal outer guide
ring. These gaskets can be used on plain flat face flanges and on
raised face flanges. The outer guide ring serves to center the gasket
properly in the flange joint, acts as an anti-blowout device, provides
radial support for the Spiral Wound components, and acts as a
compression gauge to prevent the Spiral Wound component from being
crushed. Normally the outer guide rings are furnished in mild steel,
but can be supplied in other metal when required by operating
conditions.
