The sealing flange is a device for sealing one end of a pipeline, and the sealing principle of the flange is extremely simple. But this also leads to a break of the seal. In order to maintain the seal, a significant bolt force must be maintained. For this reason, the bolts are made larger. Larger bolts are matched to larger nuts, which means that larger diameter bolts are required to provide for tightening the nuts. It is not known that the larger the diameter of the bolt, the more the applicable flange becomes bent, and the only way is to increase the wall thickness of the flange part. The entire installation will require a great size and weight, which is a particular problem in offshore environments, since weight is always a major concern in such cases. Furthermore, the ANSI flange is fundamentally an ineffective seal requiring 50% of the bolt load to compress the gasket, with only 50% of the load remaining to maintain pressure.
