Metal spiral wound gasket is a widely used sealing gasket, which is made of "V" or "W" shaped metal strips and other alloy materials such as graphite, polytetrafluoroethylene, asbestos free and other soft materials that overlap and spiral wound with each other. According to its formula, process, performance, and usage, it can withstand high temperature, high pressure, and adapt to working environments under ultra-low temperature or vacuum. By changing the material combination of the gasket, the problem of chemical corrosion of the gasket by various media can be solved. Its structural density can be made according to different locking force requirements. To strengthen the main body and accurately locate, the spiral wound gasket is equipped with metal reinforcement rings and external positioning rings, Use inner and outer steel rings to control their maximum compression.
