ASME B16.5 A105 Pipe Fittings Flange Petrochemical Pipeline Connection

Flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and add flange pads between the two flanges and fasten them together with bolts to complete the connection. . Some pipe fittings and equipment 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 greater pressure. In the industrial pipeline, in the household, the pipeline diameter is small, and it is low pressure, and the flange connection is not visible. If in a boiler room or production site, there are flanged pipes and equipment everywhere

According to the connection method, the type of flange connection can be divided into: plate flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck butt welding ring Loose flange, flat welding ring loose flange, ring groove face flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-shaped blind plate, butt welding ring loose flange, etc.
