Spiral wound gaskets are made by winding alternating metal strips and filler materials on an inner ring made of special steel. Designed to easily balance any changes in temperature and pressure during the sealing process to ensure an
excellent and safe seal.
Although the basic materials are carbon-rich, stainless steel, and flexible graphite; these materials can be changed according to various factors. The main factors that help determine the materials used include chemical compatibility,
fluid concentration, corrosivity, operating temperature and material cost.
Spiral wound gaskets have multiple functions, such as filling, sealing, leak-proofing, installation, preventing environmental pollutants, and minimizing vibration. It can work well in high pressure, high temperature, and corrosive
environments, and requires a smaller clamping force than solid washers.
