Flange (flange), also known as flange, flange disc, spline flange. Our company can be customized according to customer needs. Flange is referred to as flange, which is just a general term. It usually refers to opening several fixed holes on the periphery of a disc-like metal body to connect other things. This type of product is widely used in machinery, so it looks strange. As long as it is called flange, its name comes from English flange. The parts that connect tubes to each other. Attach to tube end. There are holes on the flange, which can be threaded with bolts to make the two flanges tightly connected. The flanges are sealed with gaskets. Flanged pipe fitting (flanged pipe fittings) means a pipe fitting with a flange (flange or hub). It can be made by casting, or by screwing or welding. Flange joint consists of a pair of flanges, a gasket and a number of 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 surface of the gasket will be deformed after reaching a certain value, and the uneven parts on the sealing surface will be filled up to make the connection tight and leak-free. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction. The flange connection is easy to use and can withstand greater pressure. In the industrial pipeline, the use of flange connection is very extensive. In the family, the pipe diameter is small, and is low pressure, can not see the flange connection. If in a boiler room or production site, there are flanged pipes and equipment everywhere. In layman's terms, the role of the flange is to make the pipe connection fixed and sealed.
