Material and sealing performance of stainless steel butt welding flange pad

Release Date: February 13, 2017


According to different levels of pressure, stainless steel butt-welded flange pads also have different materials, from low-pressure asbestos pads, high-pressure asbestos pads to metal pads. Butt-welded flanges are produced and produced in different ways and processes in actual production and development. They are carried out in accordance with process methods and principles, which have important values and effects on different aspects. Adding certain elements to increase The characteristics and value of carbon steel flanges show good use characteristics and values. The flange connection is easy to use and can withstand large pressures.

In industrial pipelines, butt-welded flange connections are widely used. In the home, the pipe diameter is small and the pressure is low, but the butt welding flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment are everywhere.

1. Connect the pipeline and maintain the sealing performance of the pipeline;

2. It is convenient to replace a certain section of pipeline; carbon steel is also called carbon steel, which refers to iron-carbon alloy with carbon content WC less than 2%.

Carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon.

3. Easy to open and check the condition of the pipeline;

4, to facilitate the closure of a certain section of pipeline.

Japan's butt welding flange industry has a history of more than half a century, during which it supported Japan's machinery industry and contributed greatly to Japan's economy. The Japan Forging Association and Japan Forging Technology Research Institute will be integrated in June 2002. The purpose is that members of the two organizations can strengthen the organization and its functions so that it can operate more efficiently. This will strengthen the service to members, in line with modern trends, and in line with the international forging industry. Butt welding flange mainly refers to the mechanical properties depend on the carbon content of the steel, and generally do not add a large amount of alloying elements of steel, sometimes also known as ordinary carbon steel or carbon steel.

Alloy steel carbon steel tees, flanges, reducers and other high, medium and low pressure fittings have today's first-class production equipment testing equipment at home and abroad and various specifications of pipe elbow flange assembly lines including cold forming hot push-pull forging heat treatment forging press processing Various craftsmanship companies also have a variety of testing equipment such as non-destructive testing chemical analysis metallographic examination physical experiments and other strong technical force can produce a variety of stainless steel flanges, tees, reducers and other products Selected by the State Power Corporation of the Ministry of Chemical Industry as the designated cooperative manufacturer.
