Special spiral wound gasket flange inner stainless steel spiral wound gasket graphite spiral wound gasket

Spiral wound gasket is to be constructed as alternate plies of preformed metal winding 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 metal 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.
A spiral wound gasket may include a center ring, an inner ring or both. The center ring enters the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reduces flange erosion and protects the sealing element. Resilience and strength make spiral wound gasket an ideal choice under a variety of conditions and applications. Widely used in refineries and chemical processing plants, spiral wound gasket is also effective for power generation, aerospace, and a variety of valve and special applications. The spiral wound gasket industry is looking for change in the specification covering spiral wound gasket. As environmental regulations and industry requirements become increasingly stringent, new and custom applications are continuing to evolve. Wherever you need a strong, resilientb seal, our spiral wound gasket provides an effective solution.
