Depending on the level of pressure, the welded flange pads are also available in different materials, from low pressure asbestos pads, high pressure asbestos pads to metal pads. The welding flange is produced and produced in different ways and processes in actual production and development. According to the process and principle, it has important value and effect on different aspects, adding certain elements in actual production. The characteristics and value of carbon steel flanges, showing good use characteristics and value. The flange connection is easy to use and can withstand large pressures.

In industrial piping, the use of butt flange connections is extensive. In the home, the pipe diameter is small and low pressure, and the weld flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
1. Connect the pipeline and maintain the pipeline sealing performance;
2, to facilitate the replacement of a certain section of pipeline; carbon steel is also called carbon steel, refers to iron-carbon alloy containing less than 2% carbon content WC.
Carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon.
3. It is easy to open and inspect the pipeline;
4. It is convenient to close a certain pipeline.
Japan has been in the industry for welding flanges for more than half a century, during which time it supported the Japanese machinery industry and contributed greatly to the Japanese economy. The Japan Forging Association and the Japan Forging Technology Research Institute will be integrated in June 2002, with the goal of strengthening the organization and its functions to enable it to operate more efficiently. This will strengthen the service to members in order to comply with the modern trend and integrate with the international forging industry. Butt welding flange mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a large amount of alloying elements, sometimes called ordinary carbon steel or carbon steel.
Alloy steel carbon steel tee, flange, reducer and other high, medium and low pressure pipe fittings have the first-class production equipment testing equipment at home and abroad and various specifications of pipe fitting elbow flange assembly line. Cold forming hot push-pull forging heat treatment forging press processing, etc. A variety of process companies also have a variety of testing equipment, such as non-destructive testing chemical analysis, metallographic examination, physical experiments, and other strong technical force to produce American standard Japanese standard GB standard specifications of stainless steel flanges, three-way, reducer and other products Selected by the National Electric Power Corporation of the Ministry of Chemical Industry as a designated cooperative manufacturer.
