Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, and between the two flanges, add flange pads and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have their own flanges, which are also flange connections. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand high pressure. In industrial pipes, in the home, the diameter of the pipe is small, and it is at low pressure, and the flange connection is not visible. If you are in a boiler room or at a production site, there are flanged pipes and equipment everywhere.
According to the connection method, the flange connection can be divided into: plate flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, loose ring flange with neck, flat welding ring loose flange, ring groove surface flange and flange cover, large diameter flat flange, large diameter high neck flange, figure eight blind plate, butt welding ring loose flange, etc.
