316 Stainless Steel Slip on Flange is not only saves space, reduces weight, more important is to ensure that the joint parts will not leak, with good sealing performance. The compact flange size is reduced by reducing the diameter of the seal, which will reduce the cross section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing surface. In this way, very little pressure is needed to compact the cover. With the reduction of the required pressure, the size and number of bolts can be reduced accordingly, so a new product has been designed that is small in size and light in weight (70% ~ 80% less than the weight of the traditional flange). Therefore, flat welding flange type is a better flange product, reduce the quality and space, for industrial use plays an important role.
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.
