The purpose of flange

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 come with flanges, which are also flange connections. Flange connection is an important connection method in pipeline construction. Flange connections are easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. Inside the home, pipes are small in diameter and low pressure, with no visible flange connections. If you are in a boiler room or production site, there are flange-connected pipes and equipment everywhere.

According to the connection method, flange connection types 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 sleeve flange, flat welding ring loose sleeve flange, ring grooved surface flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-shaped blind plate, butt welding ring loose sleeve flange, etc.
