Flange connection is an important and widely used connection method in pipeline engineering. The so-called "flange connection" is to fix two pipes, pipe fittings or equipment on a flange first, then add a flange gasket between the two flanges, and then use bolts to connect the two flanges. The discs are pulled tight to hold them tightly together. However, the quality of flange sealing performance will be affected by many factors.
