When choosing the oval gasket, users should consider whether the gasket can be used for a long time under harsh conditions. The conditions that can ensure its sealing effect are to have the following characteristics:
- Airtightness: For the medium of the sealing system, the gasket will not leak during a certain period of operation at the recommended temperature and pressure.
- Compressibility: After tightening the connecting bolts, the contact surface between the gasket and the flange should match to ensure the sealing effect.
- Creep resistance: Under the influence of pressure load and operating temperature, the gasket should have good creep resistance, otherwise it will cause bolt torque loss, resulting in reduced surface stress of the gasket and leakage of the hard gas system.
- Chemical corrosion resistance: The gasket should not be corroded by chemical media and should not contaminate the media.
- Resilience: Even in a stable system, there will definitely be slight displacement between the two connected flanges due to temperature and pressure effects-
- Anti adhesion: The gasket should be easy to remove from the flange during use and will not adhere.
- Non corrosive: The gasket is non corrosive to the flange surface of the connection.
- Temperature resistance: The gasket should be able to ensure normal use at the lowest and highest temperatures of the system.
