Flange (flange is also called flange or flange. It is a part that connects the pipe to the pipe. It is connected to the end of the pipe. There are holes in the flange that can be bolted to make the two flanges tight. The gasket is used between the flanges. Sealed. Flanged pipe fittings refer to pipe fittings with flanges (flange or joints). It can be cast, can also be formed by screwing or welding. Flange (joint) by a pair of methods Blue, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the specific pressure on the gasket surface will deform when it reaches a certain value and fill the unevenness on the sealing surface To make the connection tight and tight. Some pipe fittings and equipment already have flanges, which is also a flange connection. Flange connection is an important connection method for pipeline construction.
The flange connection is easy to use and can withstand large pressures. The flange connection is widely used in industrial pipelines. In the home, the pipe diameter is small and the pressure is low, so the flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment are everywhere.
Generally speaking, the function of the flange is to fix and seal the joint of the pipe.
