Spiral Wound Gasket
Spiral Wound Gasket Characteristic
Spiral wound gaskets are to be constructed as alternate plies of preformed metal windings and plain fillers that are spirally wound when compressed between two flanges. A "v" and "w" shaped crown centered in the metal strip acts as a spring, giving gaskets greater resilience under varying conditions. Filler and strip materials can be changed to accommodate different chemical compatibility requirements. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal.
