In the specific model selection and installation, all kinds of spacers are in extreme applications in the natural environment, to ensure long-term ability to have sealing effects, it must have the following key features:
1. Sealing of the gasket: For the material of the sealing system software, the gasket does not generate a leak in a certain period of time in highly recommended temperatures and working pressure.
2. Fluid density of the gasket: After the surface of the gasket and the flange is tightened in the coupling foot bolt, it should be very suitable to ensure sealed.
3. The anti-strain resistance of the gasket: the gasket should be relaxed in the working pressure load and the application temperature, otherwise, it will return to the surface bolt torque damage, resulting in a reduction in the surface of the gasket, thereby The bottom gas system is leaking.
