Pipe Flanges

Pipe Flanges are widely used as a popular category of pipe fittings. A flange is used to mechanically connect two pipes together. It can also be used to mechanically connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange.

A flange can also be a plate for covering or closing the end of a pipe. This is a Blind Flange. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface

Flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively, add flange gasket between the two flanges, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which also belong to flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can bear large pressure. Flange connection is widely used in industrial pipelines. In the family, the pipe diameter is small, and it is low-pressure, so the flange connection can not be seen. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.

According to the connection mode, the types 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, loose flange with neck butt welding ring, loose flange with flat welding ring, ring groove surface flange and flange cover, large-diameter flat flange, large-diameter high neck flange, spectacle blind plate, loose flange with butt welding ring, etc.
