Gaskets - Installation requirements for sealing gaskets:
1. The sealing surface of gasket and flange should be cleaned without any 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 outer surface of the flange sealing surface, and the inner diameter of the sealing gasket should be slightly larger than the inner diameter of the pipe. The difference between the two inner diameters is generally 2 times the thickness of the sealing gasket to ensure that the inner edge of the sealing gasket does not extend into the container or pipeline after compression, so as not to hinder the flow of the fluid in the container or pipeline.
3, the sealing gasket preloading force should not exceed the design provisions, so as to avoid the sealing gasket over-compression loss of rebound ability.
