Product Name: Flexible Graphite Spiral Wound Gasktet with Inner and Outer Ring Model NO.: With Outer and Inner Ring(Style RWI) Standard: Standard Shape: O-Ring Performance: Temperature Type: Fixed Seal Application: Flanges Material: Graphite Stainless Steel Carbon Steel Trademark: Yiyu Transport Package: Wooden Case or According to Your Request Specification: Standard, ASME B 16.2/ ISO 9001/ API 6A Origin: Wenzhou, China HS Code: 7318220000 Product Description Spiral wound gaskets-made with an alternating combination of formed metal wire and soft filler materials form avery effective seal when compressed between two flanges.A v-shaped crown centered in the metal strip acts as aspring, giving gaskets greater resiliency under varying conditions. Filler and wire material can be changed to accommodate different chemical compatibility requirements.Fire safety can be assured by choosing flexible graphiteas the filler material. If the load available to compress a gasket is limited, gasket construction and dimensions canbe altered to provide an effective seal.A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring centers 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.Resiliency and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications. Widely used throughout refineries and chemical processing plants, spiral wound gaskets are also effective for power generation, pulp and paper, aerospace, and a variety of valve and specialty applications.
