Gaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since the machined surface cannot be perfect, the irregularities can be filled with spacers. Now, let's take a look at the installation requirements of Pe Gasket :

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 gasket should be smaller than the outer diameter of the flange sealing surface, and the inner diameter of the 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 gasket to ensure that after pressing The inner edge shall not protrude into the container or pipe so as not to obstruct the flow of fluid in the container or pipe.

3. The pre-tightening force of the sealing gasket should not exceed the design requirements, so as to avoid excessive compression of the sealing gasket and the loss of resilience.​​
