Flange connection

Flange (flange) connection is to fix two pipes, pipe fittings or equipment first on a flange, between the two flanges, add a flange gasket, and fasten 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 for pipeline construction. The flange connection is easy to use and can withstand greater pressure. 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 it is in a boiler room or production site, there are flanged pipes and equipment everywhere.
