Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
According to the connection method, the flange connection type 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, butt welding ring with neck Loose flanges, flat welding ring loose flanges, ring groove face flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, eight-character blind plates, butt welding ring loose flanges, etc.
