The flange is a part which is connected between the pipe and the pipe, which is used for the connection between the pipe end. Forged flange connection is the two pipes, pipe fittings or equipment, and forging a connection is an important way to connect the pipeline construction, the use of forged flange connection is convenient, can withstand greater pressure. In the industrial pipeline, the use of forging flange connection is very extensive. The production process of forging flange is composed of the following steps: selection of high quality steel billet, heating, forming, cooling after forging, the size of the quality of the forging, the number of different forging method to produce a lot of quantities.
