What is the main purpose of flat gaskets? -

The flat gasket is a widely used sealing flat gasket at present. It is a flat gasket with good resilience among the semi-metallic gaskets. It is made of V-shaped or W-shaped thin steel strips and various fillers alternately wound. High temperature, high pressure and suitable for ultra-low temperature or vacuum conditions. By changing the material combination of flat gaskets, the problem of chemical corrosion of flat gaskets by various media can be solved. Its structural density can be made according to different locking force requirements. In order to strengthen the main body and accuracy, the spiral wound flat gasket is equipped with a metal inner reinforcement ring and an outer ring. The inner and outer steel rings are used to control the large compression degree, and the surface accuracy of the flange sealing surface contacted by the gasket is not high. What are the main uses of this powerful flat gasket? The metal wound flat gasket with excellent resilience can automatically adjust the pressure thermal cycle and vibration of the piping system, and is especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. It is the original static seal of the flange joints of valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace departments. For the convenience of installation in the appearance design of the flange gasket, 2~8 straps are welded on the periphery of the flat gasket according to the size of the gasket, so that the strap is buckled on the flange hole to prevent the flat gasket from shifting or falling off during installation. It saves auxiliary materials and man-hours. Generally divided into the following types: Flat gaskets are made of high-quality SUS304, SUS316 ('V'-shaped or'W'-shaped), metal belts and other alloy materials and graphite, asbestos, and PTFE Soft materials such as gaskets and non-asbestos are alternately overlapped and spirally wound. The metal band is fixed by spot welding at the beginning and the end. Metal spiral wound gaskets are semi-metallic gaskets with good resilience. The structure density of metal spiral wound gaskets can be made according to different locking force requirements, and the inner and outer steel rings are used to control its large compression. The surface accuracy of the flange sealing surface contacted by the sheet is not high. Flat gaskets are especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Flat gaskets are static sealing elements for flange connection processing such as valves, pumps, heat exchangers, towers, manholes, and hand holes. Application range of flat gaskets: Sealing of flange joints such as pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgical, electric power, shipbuilding, machinery and other industries.
