The installation process of Flange Insulation Gasket Kit
The inner diameter (inner diameter) of the gasket is usually slightly smaller than the inner diameter of the flange. When installing, make sure the gasket is correctly aligned with the center of the hole. This can prevent foreign matter from accumulating between the flange faces during the pigging process.
It is recommended to use the single gasket insulating sleeve of Kammprofile Gaskets Suppliers for underground flanges. It should be installed on the unprotected side of the flange, which will provide cathodic protection for the studs and nuts. For above-ground flanges, it is recommended to use double washers to facilitate testing.
It is always recommended to use positioning pins to ensure proper alignment of flanges and gaskets. The size of each pin should be at least 3/32 inches (2.38 mm) larger than the bolt.
The installation process of each Flange Insulation Gasket Kit usually comes with a diagram showing the recommended bolt tightening sequence.
