The metal winding gasket is made of high quality SUS304, SUS316 ("V" or "W" shape) metal belt and other alloy materials and graphite, asbestos, PTFE, no asbestos and other soft materials, and the metal belt is fixed by spot welding at the beginning and ending. The metal winding gasket is the gasket with the best return elasticity in the half-metal composite cushion. The structural density of the metal winding gasket can be made according to different locking force requirements, the internal and external steel rings are used to control the maximum compression degree. The surface accuracy of the flange sealing surface contacted by the winding gasket is not high. Metal winding gasket is especially suitable for uneven load, easy joint force relaxation, temperature and pressure periodic change, impact or vibration occasions. Winding gasket is an ideal static sealing choice for flange joints such as valves, pumps, heat exchange, towers, manholes and hand holes.

Scope of application of spiral wound gasket

Petroleum, chemical industry, metallurgy, electric power, ships, machinery, and other industries of the pipeline, valves, pressure vessels, condenser heat exchange, tower, manhole, hand holes and other flange joint sealing.
