The metal winding gasket is currently widely used in a sealing spacer, a preliminary spacer in a semi-metallic adaptive pad, which is formed by alternating the V-shaped or W-shaped steel strip with various filler.
It can be used with high temperature, high pressure and adaptation of ultra-low temperature or vacuum, by changing the material combination of the gasket, can solve the problem of chemical corrosion of the gasket, and the structural density can be made according to different locking force requirements. Strengthen the main body and accurate positioning, the winding gasket is provided with a metal reinforcing ring and an outer positioning ring, and the inside and outside steel rings are used to control its larger pressure, the surface precision requirements of the flanged cover of the gasket is not high.
