Flange is connected to pipe end. There are holes on the flange, which can be threaded with bolts to make the two flanges tightly connected; the flange and the pipe are welded together. The flange connection consists of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the two flange sealing surfaces. After the nut is tightened, the specific pressure on the gasket surface reaches a certain value, which causes deformation, and fills the uneven parts on the sealing surface, so that the connection is tight. Some pipe fittings and equipment have their own flange, which also belongs to flange connection. Flange connection is an important way of pipeline construction. Flange is manufactured according to the standards of ASME B16.5/MSS SP-44, GB, HG, SH, etc..
