Flange connection

　　Flange ( flange) connection is to fix two pipes, pipe fittings or equipment respectively on a flange plate first, between the two flange plates, add flange pads and fasten them together To complete the connection. Some pipe fittings and equipment already have 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 large pressures. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small and the pressure is low, so the flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment are everywhere.
　　According to the connection method, the flange connection types can be divided into: plate type flat welding flange, neck flat welding flange, neck welding flange, socket welding flange, thread flange, flange cover, neck welding ring Loose sleeve flanges, flat welding ring loose sleeve flanges, ring groove face flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, blind straight plates, butt welding ring loose sleeve flanges, etc.
