Application of spiral wound gasket
The metal spiral wound gasket with excellent resilience can automatically adjust the pressure thermal cycle and vibration of the pipeline system, especially suitable for the occasions where the load is uneven, the bonding force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. It is a static sealing element of flange joints such as valves, pumps, heat exchangers, towers, manholes and handholes. It is widely used in petrochemical, mechanical, electric power, metallurgy, shipbuilding, medicine, atomic energy, aerospace and other departments.
In order to facilitate the installation of the flange gasket, according to the diameter of the gasket, 2-8 positioning belts are welded on the periphery of the gasket, and the positioning belt is buckled on the flange hole to prevent the gasket from shifting or falling off during installation, It is generally divided into the following types: metal spiral wound gasket is made of high-quality SUS304, SUS316 (V-shaped or W-shaped) metal belt and other alloy materials, alternately overlapped with graphite, asbestos, polytetrafluoroethylene gasket, non asbestos and other soft materials. The metal belt is fixed by spot welding at the beginning and end.
The spiral wound gasket is the gasket with the best resilience in the semi metal sealing gasket. The structural density of the metal spiral wound gasket can be made according to different locking force requirements, and the maximum compression degree is controlled by using the inner and outer steel rings. The surface accuracy requirement of the flange sealing surface contacted by the spiral wound gasket is not high. Metal spiral wound gasket is especially suitable for uneven load, easy relaxation of bonding force, periodic change of temperature and pressure, impact or vibration. Spiral wound gasket is an ideal static sealing element for valve, pump, heat exchanger, tower, manhole and handhole.
