Spiral wound gasket is composed of V-shaped or W-shaped stainless steel metal belt and non-metal belt alternately and spiral wound continuously. The metal belt is fixed by spot welding at the beginning and end. It has good compression performance and rebound performance, its "V" and "W" type metal winding belt can ensure good rebound performance when the stress is released, the non-metal filler belt can ensure the air tightness performance, and reduce the pre stress requirements of gasket. It is suitable for a wide range of working conditions. It can withstand high temperature, high pressure and adapt to the use conditions of ultra-low temperature or vacuum. By changing the material combination of gasket, the problem of chemical corrosion of gasket by various media can be solved. The ability of stress compensation is strong. The sealing performance is stable and reliable when the temperature and pressure fluctuate frequently. Excellent sealing performance. The requirement of surface accuracy of flange seal contacting with gasket is not high. It is easy to install and the pre tightening pressure of gasket is low.

Purpose:

It is suitable for sealing gasket of high temperature and high pressure pipeline flange and vessel flange of petrochemical, chemical fiber, chemical fertilizer, oil refining, metallurgy, shipbuilding, thermal power, nuclear power station, aerospace power and other devices.
