1. The sealing gasket and flange sealing surface should be cleaned, and there should be no scratches, spots and other defects that affect the sealing performance of the connection.
2. The outer diameter of the sealing gasket should be smaller than the outside of the flange sealing surface, and the inner diameter should be slightly larger than the inner diameter of the pipe. The difference between the two inner diameters is generally twice the thickness of the gasket to ensure that the inner edge of the gasket does not extend into the container after being compressed. Or in the pipeline, so as not to hinder the flow of fluid in the container or pipeline.
3. Gasket pre-tightening force should not exceed the design regulations, so as to avoid excessive compression of the gasket and loss of resilience.
4. It is recommended to use a torque wrench when the gasket is compressed. For large bolts and high-strength bolts, hydraulic tightening is recommended. The tightening torque should be obtained by calculation based on the compression of the given gasket, and the size of the hydraulic tightener's oil pressure should also be determined by calculation.
5. When installing the gasket, tighten the nuts in sequence. But it should not be screwed once to reach the design value. Generally, it should be cycled at least 2 to 3 times to make the stress distribution of the gasket uniform.
