Butt welding flange gasket material and sealing performance By

Written by

According to the different levels of stress, butt welding flange gasket also have different material, from the low pressure asbestos pad, high-pressure asbestos pad to metal pads. Development of butt welding flange in the actual production and used in different ways and process of production and the production, according to the process and principle, and have important value and role of different, in the actual production to add some elements increase the features and value of carbon steel flange, do well the use of the characteristics and value. Flange connection is convenient to use, can withstand greater pressure.
In industrial pipe butt welding flange connection is widely used. Within the family, pipe diameter is small, and it is low voltage, invisible butt welding flange connection. If in a boiler room or production site, the flange connection of pipes and equipment are everywhere.
1, the pipeline of pipeline connection and keep the sealing property;
2, easy to change line a long period; Carbon steel or carbon steel, carbon content WC is less than 2% of the iron carbon alloy.
Carbon steel in addition to carbon generally contain small amounts of silicon, manganese, sulfur and phosphorus.
3, easy to disassemble pipeline;
4, easy to pipeline closed a long period.
Japan’s butt welding flange industry history for more than half a century, during which underpins the machinery industry in Japan and has made great contributions to the economy of Japan. Japanese forging forging association and Japan institute of technology in June of 2002 will be consolidation, its purpose is a member of the two organizations to strengthen the organization and its functions, make them more efficient operation. So will can strengthen service for members, in order to conform to the trend of the modern, with international forging industry. Mainly refers to the mechanical properties of butt welding flange depends on the carbon content in steel, and generally do not add a lot of alloy element in steel, sometimes referred to as the carbon steel or carbon steel.
Alloy steel carbon steel tee, flange, reducer, such as the high school low pressure pipe fittings with today’s domestic and international first-class production equipment, testing equipment and a variety of specifications of the pipe elbow flange forging heat treatment line of cold forming hot push-pull forging machine such as a variety of complete technology company also has a wide range of testing equipment such as nondestructive flaw detection of chemical analysis and metallographic examination physics experiment etc. Strong technical force can produce American standard, standard gb standards of various specifications of the stainless steel flange, tee, reducer, etc. Series of products are chemical state power corporation designated as fixed-point collaborative manufacturers.
