Internal and external ring winding pads in the lower use preload the first gaskets, surface soft sealing layer avoid direct contact with the metal to metal, and can be reliable, the combination of closely, protect the metal flange was not damage, even in extremely high load. Internal and external ring winding gasket is especially suited for high temperature and high pressure, working condition alternating occasion, in the heat exchanger, container, the flange joint reaction kettle, is the traditional metal coating gaskets of ideal substitute. A performance and features. 1, suitable for high temperature, high pressure part 2, strong corrosion resistance 3, sealing function is stable, reliable 2. Use scope and parameter 1, use temperature: 650 ℃ ~ 2, use pressure: 6.4 ~ 25.0 MPa 3, minimum preloaded than pressure: y = 70 MPa 4, gasket coefficient: m = 4.25
