There are holes on the stainless steel flange, which can be threaded with bolts to connect the two flanges tightly. Gasket between flanges. Flanged pipe fittings refer to pipe fittings with flanges (lugs or adapters). It can be cast, threaded or welded. Flange joint is composed of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the two flange sealing surfaces. After tightening the nut, the specific pressure on the gasket surface will deform after reaching a certain value, and fill the uneven parts on the sealing surface to make the connection tight. Some pipe fittings and equipment have their own flanges, which also belong to flange connection. Flange connection is an important connection mode in pipeline construction. The flange connection is convenient to use and can bear large pressure. Flange connection is widely used in industrial pipelines. In the family, the pipe diameter is small, and it is low-pressure, so the flange connection can not be seen. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere. Generally speaking, the function of flange is to fix and seal the connection of pipe fittings.
Forging method. Machining flanges through forging can be divided into two types: free forging and die forging. Free forging involves compression processing under a forging press
