Flange-to-flange connection method

Flange connection refers to fixing two pipes, fittings or equipment on a flange, adding a flange gasket between the two flanges and fastening 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 mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipelines. At home, the pipe diameter is small and the pressure is low, so the flange connection is invisible. If you are in the boiler room or production site, there are flanged pipes and equipment everywhere.
