carbon steel slip on flange connection is to fix two pipes, pipe fittings or equipment on a flange, and between the two flanges, with flange pads, bolted together to complete the connection. . Some fittings and equipment have their own flanges and are also flanged. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand large pressures. Flange connections are widely used in industrial piping. In the home, the pipe diameter is small and low pressure, and the flange connection is not visible. If you are in a boiler room or production site, flanged pipes and equipment are everywhere.
