Plate flange connection is the process of fixing two pipes, fittings, or equipment onto a flange plate, adding flange pads between the two flanges, and fastening them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections. Plate flange connection is an important connection method in pipeline construction. The flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connections are widely used. In the home, the diameter of the pipeline is small and it is low-pressure, so flange connections cannot be seen. If there are flanged pipes and equipment everywhere in a boiler room or production site.
Compared to neck flanges, flat flanges can be divided into carbon steel flat flanges, stainless steel flat flanges, and alloy steel flat flanges based on their materials. The structural forms of flanges include integral flanges and unit flanges.
