A metal seal ANSI B16.20 Spiral Wound Gasket is a type of gasket that is used in high-pressure and high-temperature applications. It consists of a metal ring with a spiral wound sealing element made from alternate layers of metal and filler material. The metal ring provides structural support, while the sealing element provides a reliable seal against the flanges.
The gasket is designed to meet the standards set by the American National Standards Institute (ANSI) B16.20 specification, which outlines the dimensions and materials used in the manufacture of spiral wound gaskets. The gasket is typically used in applications involving hydrocarbons, steam, and other corrosive and high-temperature fluids.
The metal seal ANSI B16.20 Spiral Wound Gasket is available in a range of sizes and materials to suit different applications. The material used in the sealing element can vary depending on the application requirements, with common materials including graphite, PTFE, and ceramic.
Overall, the metal seal ANSI B16.20 Spiral Wound Gasket is a reliable and versatile sealing solution for high-pressure and high-temperature applications.
