product detailscurrent location ： home > Product Center > product detailsUltra low temperature resistant spiral wound gasket
Spiral wound gasket is made of V-shaped or W-shaped metal belt and non-metallic filler belt alternately overlapped, spiral wound, and end spot welding, and reinforcement ring can be added according to working conditions.
It is applicable to a wide range of working conditions. It can withstand high temperature, high pressure and the use conditions under ultra-low temperature or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of the gasket caused by various media can be solved. Strong stress compensation capability. The sealing performance is stable and reliable at the station with frequent temperature and pressure fluctuations. The sealing performance is excellent. The requirements for the surface accuracy of the flange in contact with the gasket are not high. It is easy to install, and the pre tightening pressure of the gasket is low& nbsp;
