Product Name: CS Outer Ring, Ss304 Inner Ring, Ss304 Welding, Graphite Filler, Spiral Wound Gasket with Certificate ISO9001: 2008 Model NO.: 3/4''-60'' 150-2500LB Standard: Standard, Nonstandard Shape: O-Ring Performance: Temperature Type: Stationary Seal Application: Sealing Material: stainless Steel &Garphite Trademark: YIYU Transport Package: Wood Case Specification: 3/4''-60'' 150-2500lb Origin: Wenzhou City, Zhejiang Provice, China HS Code: 8484100000 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.
