[0002] Plate-type flat-welded flange is a commonly used flange connection method. It consists of flanges welded on two planes. The flange connection is fastened by bolts to fit the two flange planes tightly together to form a sealed connection. When plate-type flat-welded flanges are used, it is necessary to consider the working conditions of the pipeline system, including pressure, temperature, medium and other factors to ensure the safety and reliability of the flange connection. In addition, it is necessary to select the appropriate flange size and material according to the diameter and material of the pipeline to ensure the tightness and durability of the connection.
