Products Description

The graphite spiral wound gasket is a semi-metallic flat gasket made by spirally winding a metal strip and a graphite non-metal strip, combining the strength of metal with the sealing property of graphite.

It has excellent compressibility and elasticity, enabling it to fit tightly against the sealing surface. It adopts a multi-channel sealing design with a certain self-tightening function, ensuring reliable sealing effect. It is less sensitive to defects on the flange sealing surface, does not adhere to the flange, is easy to center during installation, and very convenient to disassemble later.

During use, it can effectively partially eliminate the impact of pressure fluctuations, temperature changes and mechanical vibration. Even under various harsh conditions such as high temperature, low temperature, high vacuum, impact vibration and cyclic alternations, it can still maintain excellent sealing performance. Temperature-Resistant Spiral Wound Gasket it is widely used in flange connection sealing scenarios in many industries such as chemical industry, petroleum and electric power.
