316 Stainless Steel Slip On Flange

The sealing principle of  316 Stainless Steel Slip on Flange: the two sealing surfaces of the bolt squeeze the flange gasket and form a seal, but this also leads to the destruction of the seal. In order to maintain the seal, a large bolt force must be maintained, for which the bolt must be made larger. 

A larger bolt has to match a larger nut, which means a larger diameter bolt is needed to create the conditions for the tightening nut. However, the larger the diameter of the bolt, the applicable flange will become bent by increasing the wall thickness of the flange section. The overall installation will require relatively large size and weight, which is a particular problem in offshore environments, where weight is always a major concern. And, fundamentally, flat welding flanges are an ineffective seal, requiring 50% of the bolt load to be used to squeeze the gasket and only 50% of the load to maintain pressure.
