[0002] High-pressure flanges are mainly used in the installation of pipelines. High-pressure flange connection is an important connection method for pipeline construction. It is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange gaskets between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have flange plates, which also belong to flange connections. In order to increase the service life of the high-pressure connecting flange, a protective coating is generally sprayed on the flange surface to effectively prevent the high-pressure flange surface from rusting or corrosion.
