Flange connection

Flange connection is to fix two pipes, pipe fittings or equipment respectively on a flange plate first, and add flange pads between the two flange plates, and fasten them with bolts 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 piping, in the home, the diameter of the pipe is small and the pressure is low, and the flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment are everywhere. [1]
