The forming process of Xiangyang 316 large diameter butt welded elbow manufacturers includes hot pushing, stamping and extrusion. According to the angle, there are three kinds of elbow commonly used, which are 45 ° and 90 ° 180 °, In addition, according to the needs of the project, it also includes 60 ° and other abnormal angle elbows. The materials of elbows double drive plasma cutting machine include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc. the methods of connecting with pipes are: direct welding (* common way) flange connection, hot-melt connection, electric fusion connection, thread connection and socket connection, etc Under the protection of gas, chromium and nickel on the surface of stainless steel will not be oxidized, and the original characteristics and corrosion resistance of stainless steel are retained. Xiangyang 316 large diameter butt welded elbow manufacturer uses press to press directly in the mold. The data of pressing large-diameter elbow requires some special raw materials for production. These raw materials should be strictly selected and controlled, and the raw materials should be selected appropriately, otherwise the quality of the high-pressure elbow will not be guaranteed. The application data of high-pressure elbow elbow is a large class of new data with special electrical, acoustic, thermal, mechanical, chemical and biological properties. It is the main basic data of high-tech areas such as biology, technology, energy technology and national defense construction. At the same time, it also plays a major role in transforming some conservative industries, such as agriculture, chemical industry, building materials, etc. Tempering and annealing of high pressure thick wall elbow is one of the factors that determine the quality of elbow after forming. If we grasp these two links, our elbow production will be improvedProductivity. The quenched welding high-pressure elbow is reheated to a certain temperature, and then cooled by a certain method is called tempering. The purpose is to eliminate the internal stress produced by quenching, reduce the hardness and brittleness, and obtain the expected mechanical properties. According to the manufacturer GB150 of Xiangyang 316 large diameter butt welded elbow, the welding joint coefficient shall be determined according to the welding process characteristics of the welding pipe fittings of the pressure parts of the vessel (weld type: single side welding or double side welding; with or without backing plate), as well as the random inspection rate of nondestructive testing, and only the butt weld is specified. The forming process of hot pressing seamless elbow has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. Therefore, it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of high pressure seamless elbow. The heating methods of forming process include medium frequency or high frequency induction heating (the heating ring can be multiple or single ring), flame heating and reverberatory furnace heating. The heating method depends on the requirements of forming products and energy conditions. Stamping forming elbow is a forming process which has been used in mass production of high pressure seamless elbows. It has been replaced by hot push method or other forming processes in the production of elbow with common specifications. However, in some elbows, the quantity of production is small and the wall thickness is too thick or too thin. The weldability of Xiangyang hydraulic elbow duct forming machine manufacturer 316 large diameter butt welding elbow manufacturer is better than that of chromium stamping elbow. When the same type of chrome stainless steel stamping elbow is used, it should be preheated above 200 ℃ and tempered at 800 ℃ after welding. If the weldment cannot be heat treated, chrome nickel stainless steel stamping elbow shall be selected.Stamping elbow has good corrosion resistance and oxidation resistance. Its good characteristics promote its use and promotion in different fields, widely used in chemical industry, chemical fertilizer, petroleum and medicine. Medical machinery manufacturing. The data of high-pressure seamless elbow needs some special raw materials for production, these raw materials should be strictly selected and controlled, and the raw materials should be selected properly, otherwise the seamless hot hydraulic elbow duct forming machine manufacturer pressing elbow will not have quality assurance. The application data of seamless hot pressed elbow is a new type of data with special electrical, acoustic, thermal, mechanical, chemical and biological properties. It's biology. Technology, energy technology and other high-tech areas and the main basic data of national defense construction also play a major role in transforming some conservative industries, such as agriculture, chemical industry and building materials.
