[0002] Flanges used for connecting pipes or equipment with pressures higher than 10MPa mainly include traditional high-pressure flanges and high-pressure self-tightening flanges. In traditional flange connections, the gasket is installed between the two flange sealing surfaces. After the bolts are inserted and the nuts are tightened, the specific pressure on the surface of the gasket reaches a certain value, causing it to undergo plastic deformation, making the connection tight and leak-proof. This form can be used for flammable, explosive, toxic media and in situations with higher pressures, but the sealing reliability is poor.
