Large diameter carbon steel flanges are most common in pipeline engineering, and flanges are used in pairs. In pipeline engineering, large diameter carbon steel flanges are mainly used for pipe connections. In the pipeline to be connected, a variety of flanges are installed, and the low-pressure pipeline can use a wire flange. The welding flange is used at a pressure of 4 kg or more.
Apply a sealing point between the two flanges and tighten with bolts. Flange connection is to fix two pipes, pipe fittings or equipment to each one on a flange, between the two flanges, with flange pads, bolted together to complete the connection. Some fittings and equipment already have flanges and are also flanged. Flange connections are widely used in industrial piping.
