Flat welding flange sealing principle: two sealing surface compressive flange gasket bolt and form a seal, but it also led to the destruction of the seal. In order to keep the seal, will have to maintain a huge bolt force, therefore, the bolt will be bigger. And a bigger bolt will match the bigger nut, which means the larger diameter bolts to create conditions to tighten the nut. However, the diameter of the bolt, the greater the applicable flange will become bent, the only way is to increase the flange part of the wall thickness. The whole device will requires a great deal of the size and weight, this in the offshore environment has become a special problem, because in this case the weight of people must concern has always been the main problem.
