Flange connection is to fix two pipes, pipe fittings or equipment respectively on a flange plate, and the flange pad is added between the two flanges, which is fastened together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand large pressure. In industrial piping, in the home, the pipe diameter is small, and is low pressure, no flange connection visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere. [1]
According to the connection flange connection types can be divided into: plate flat welding flange, with flat welding neck flange, butt welding neck flange, socket welding flange, threaded flange, flange cover, with neck butt welding ring flange, ring flat welding flange come loose, ring groove surface flange, flange cover, large diameter plate flange, large diameter high blind flange, butt welding neck flange, eight words ring loose flange, etc. [3].

As welded iron flanges, many customers question whether the quality of welded iron flanges is better than forged welded flanges. Actually iron plate welding quality and the quality of the welding flange forging flange is the same, but the iron plate welding flange exactly what place can not be guaranteed, is also the most insecure iron plate welding flange material, because the process of general, the density of iron plate welding flange is no problem, but in the process of producing, The blank of the iron plate welding flange is rarely tested, so after the production, the material of the iron plate welding flange can not be guaranteed without testing.
