According to the pressure of different grades and butt welding flange also have different materials, from the low-pressure asbestos pad, high pressure asbestos pad to the metal pads. In the actual production and development of the use of different methods and processes for production and production, the performance of good use of characteristics and value. Flange connection is easy to use, can withstand greater pressure. In the industrial pipeline, welded flange is widely used. Within the family, the small diameter of the pipe, and low pressure, invisible welded flange. If in a boiler room or in the production site, there are all of the flange connection pipe and equipment.
A, a connecting pipeline and maintain the performance of sealing pipeline, welding neck flange mainly refers to the mechanical properties depending on the carbon content in steel, and generally do not add a lot of alloy elements of steel, and is sometimes referred to as plain carbon steel or carbon steel.
Two, for the replacement of a pipeline steel; also called carbon steel, refers to the iron carbon alloy carbon content less than 2% WC.
Carbon steel contains a small amount of silicon, manganese, sulfur, phosphorus, carbon addition.
Three, easy to disassemble and check the pipe line;
Four, easy to close the pipeline.
Japan welding neck flange industrial history has been more than half a century, during which support Japan's machinery industry and have a great contribution on the economy of Japan. Japan Forging Association and the Japanese Forging Technology Research Institute in June 2002 will be integrated, which aims to strengthen the organization and function of the two members of the organization, so that it can more efficient operation. So will strengthen the service to the member, in order to conform to the modern trend, with the international forging industry.
Hebei Shengtian pipe fittings Group Co., Ltd. has nowadays domestic and international first-class production equipment, testing equipment and a variety of specifications of elbow pipe fittings flange pipeline, the cold forming may pull forging heat treatment, forging machine and various process is complete, the company also has a variety of testing equipment such as non destructive chemical analysis and metallographic examination of physical experiment, and strong technical force, the production of American Standard, GB standard of various specifications of the stainless steel flange, tee, reducer, etc. series products.
