In the actual selection and installation process of elliptical gaskets, any type of gasket must have the following eight important characteristics to ensure long-term sealing in harsh use environments:
1. Airtightness of gasket
For the medium of the sealing system, the gasket should work at the recommended temperature and pressure for a certain period of time without leakage.
2. Compressibility of gaskets
The contact surface between the gasket and the flange should be able to fit well after the connecting bolts are tightened to ensure sealing.
3. Creep resistance of gaskets
Under the influence of pressure load and operating temperature, the creep resistance of the gasket should be good, otherwise it will cause loss of bolt torque, resulting in a decrease in surface stress of the gasket and leakage of the hard gas system.
4. Chemical corrosion resistance of gaskets
The selected gasket should not be corroded by chemical media and should not contaminate the media.
5. Resilience of gaskets
Even under stable system conditions, there will definitely be slight displacement between the two connected flanges due to temperature and pressure effects. The elastic function of the gasket should be able to compensate for this displacement to ensure the sealing of the system.
6. Anti adhesion of gaskets
The gasket should be easy to remove from the flange after use without sticking
7. Non corrosive properties of gaskets
The gasket should be non corrosive to the flange surface of the connection.
8. Temperature resistance of gaskets
The selected gasket should ensure normal use at the lowest and highest temperatures of the system.
There are many types of RTJ gaskets, including R Gasket,RX Gasket,BX Gasket, SBX Gasket,IX Gasket,and various customized products.We will do more sharing about ring joint gasket.
