Basic Type Standards ASME Spiral Metal Ring Gasket Material ss316 Filler Graphite Sealing
CHARECTERISTIC
1. The applicable working condition range is wide. Can resist high temperature, high pressure, and adapt to the use condition of ultra-low temperature or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of the various media to the gasket can be solved.
2. The stress compensation ability is strong. The sealing performance is stable and reliable at the station with frequent temperature and pressure fluctuation.
3. The sealing performance is excellent.
4. The surface accuracy requirement for flange sealing contact with the gasket is not high. 5.The installation is convenient, and the pre-tightening pressure of the gasket is low.
