Spiral wound gaskets - made with an alternating combination of formed metal wire and soft filler materials - form a very effective seal when compressed between two flanges. A V-Shaped crown centered in the metal strip acts as a spring, giving gaskets greater resiliency under varying conditions. Filler and wire material 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 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. Kraft Industrial Supply stocks a large inventory of 900# rated spiral wound gaskets with no retaining rings in high temperature Type 347 Stainless Steel for use in valve bonnet service.
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, aerospace, and a variety of valve and specialties applications.
As environmental regulations and industry requirements become increasingly stringent, new and custom applications are continuing to evolve. Wherever you need a strong, resilient seal, our spiral wound gaskets provide an effective solution.
