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.
