Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, which is also a flange connection. Flange connection is an important connection method for pipeline construction.
The 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 invisible. If it is in a boiler room or production site, flanged pipes and equipment are everywhere.

According to the connection method, the type of 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, butt welding ring with neck Loose flanges, flat welded ring loose flanges, ring groove face flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, eight-shaped blind plates, butt weld ring loose flanges, etc.
