Discussion On Selection Of Material For Sealing Gasket
The choice of gasket material depends on the industrial and mining, such as: pressure, temperature, medium corrosion and so on. The commonly used gaskets are non-metallic gaskets, semi metal gaskets and metal gaskets. Non-metallic gaskets are also known as upholstered pads, such as asbestos rubber sheets, rubber, PTFE, and cushion pads for occasions where temperature and pressure are not high. Semi-metal gasket consists of metal data and non-metallic materials, such as flexible graphite composite pad, spiral wound gasket, metal cladding pad, etc. The temperature and pressure of half metal gasket are wider than that of nonmetal gasket. Metal gaskets are all made of metal, have waveform, tooth shape, oval, octagonal, lens pad, cone cushion and so on. Metal gaskets are used for high temperature and high pressure occasions.
