Selection of gaskets

Sealing gasket selection Any type of gasket, in a harsh environment, to ensure effective sealing with a long mechanical seal time, it must have the following eight important characteristics: The airtightness of the gasket is essential to the sealing system The medium and gasket will not leak within a certain period of time at the recommended temperature and pressure of the mechanical seal. The compressibility of the gasket The contact surface of the gasket and the flange should be able to match the mechanical shaft seal well after the connecting bolts are tightened to ensure the seal. The creep resistance of the gasket The gasket should have good creep resistance under the influence of pressure load and operating temperature. Otherwise, it will cause the loss of bolt torque, which will reduce the surface stress of the gasket and cause the hard gas system to leak. Gasket resistance to chemical corrosion The selected gasket should not be corroded by chemical media and should not contaminate the media.
