Construction of Spiral Wound Gaskets

Spiral wound gaskets are made by winding alternating layers of a metal strip, typically stainless steel or another corrosion-resistant alloy, and a filler material, such as graphite or PTFE. The metal strip provides structural strength and resilience, while the filler material offers excellent sealing performance and conforms to the flange surfaces, ensuring a tight seal. The gasket's winding process creates a V-shaped profile that allows the gasket to compress under load and maintain its sealing properties even when subjected to pressure and temperature fluctuations.
