Chemical industry pipelines often experience leakage and leakage during long-term use, posing safety hazards that are difficult to cure. On July 4-5, at the Qingdao University of Science and Technology Lanshi Heavy Equipment (5.040, ± -0.02, ± 0.40%) company's cutting-edge technology exchange meeting held in Lanzhou, the high-pressure self tightening flange ZY-LOC was launched, which can become a solution to the problems of chemical pipeline leakage and external leakage. Zhang Pulin, Chairman of Lanshi Heavy Equipment Co., Ltd., stated that Lanshi Heavy Equipment and Qingdao University of Science and Technology have jointly launched a new pipeline connection technology, the high-pressure self tightening flange ZY-LOC, through industry university research cooperation. This technology has solved industry problems and achieved mutual promotion and a virtuous cycle between university technology platforms and equipment manufacturing enterprises. According to Xu Zhi, the general manager of Lanzhou Lanshi Zhiyuan Machinery Technology Co., Ltd., there are only four similar products of high-pressure self tightening flanges worldwide. Although the basic principles are the same, the ZY-LOCT ring has a longer T-shaped arm and stronger bending and torsion resistance. He introduced, "ZY-LOC products have a diameter of DN15~DN1000, a pressure PN ≤ 150MPa, a temperature of -196 ℃~800 ℃, and are suitable for various high and low temperature environments and different forms of media The former deputy commander of a certain navy fleet proposed suggestions for the new flange products: firstly, the conditions of the offshore platform are harsh, and the products must meet or exceed the quality level of foreign flanges under the same material and process of homogeneity; Secondly, all tank outlet connections must address leakage issues to ensure that the entire project pipeline is leak free; The third is to achieve mass production as soon as possible to reduce flange prices. Qin Youfu, the project manager of Sinopec Engineering Construction Company, introduced the application of ZY-LOC. The high-pressure self tightening flange used in the Shenhua coal direct liquefaction unit has been in good condition for 13 years and is still leak free. After adopting ZY-LOC in the reforming unit of Anqing Petrochemical, there have been no further leaks caused by gasket damage. Afterwards, Jiujiang Petrochemical, Qingdao Refining and Chemical, Guangzhou Petrochemical, Jinling Petrochemical, Qilu Petrochemical, and Zhenhai Petrochemical also adopted ZY-LOC in large-scale petrochemical projects. Lu Huiming, the head of the Middle East region of the Industrial Development Promotion Association of the National Development and Reform Commission, believes that due to the excellent technology of ZY-LOC products and the recognition of Chinese manufacturing by overseas enterprises, ZY-LOC will have good application prospects in oil producing countries in the Middle East.

Manufacturing process of forged socket three-way connectors by manufacturers 2024-05-28

　　Forging high-pressure tees, broadly known as "forging", is a broad concept that refers to the manufacturing of pipes, plates, and forgings as raw materials. Its manufacturing method includes almost all the forming processes of pipe fittings. When it comes to specific varieties (including all varieties of socket welding and threaded fittings, branch fittings, and other fittings that require forging, such as thick walled forged tees), the so-called "forging" corresponds to the English word "forged", which refers to fittings that are mainly formed by forging. The content mentioned here refers to the latter type of forging. According to the different varieties and requirements of pipe fittings, forging of pipe fittings mainly adopts forging, free forging, and cutting forming processes. The common forging method has large burrs and consumes materials. In order to reduce material consumption, some pipe manufacturers have begun to use forming processes without burrs, achieving good results. This section mainly introduces the process of forging, free forging, and cutting to manufacture pipe fittings. 　　The high-pressure tee is finely forged, with a smooth surface, acid, alkali, and high temperature resistance. The price calculation is reasonable, the appearance is beautiful, and the texture and performance are strong. Its main function is to change the direction of the fluid. Having three openings, namely one inlet and two outlets; A type of chemical pipe fitting with two inlets and one outlet, which can be T-shaped or Y-shaped, with equal diameter pipe openings and reducing diameter pipe openings, used for the convergence of three identical or different pipelines. 　　Forging tee quenching aging: the phenomenon of the performance of forging tees changing over time after rapid cooling at high temperatures. The carbon content, degree of deoxidation, and nitrogen content in steel have a significant impact on quenching aging. Boiling steel with low forging and insufficient deoxidation, as well as steel with high nitrogen content, undergo significant quenching aging. For medium forging with a carbon content of about 0.3%, the performance changes caused by quenching aging have been greatly reduced, while high forging with a carbon content of about 0.6% does not actually have an aging hardening effect. 　　Alloy tee manufacturer 　　Due to the usually thick wall thickness of forged high-pressure tee pipes, the commonly used testing method for forged alloy tees is ultrasonic flaw detection. This method can effectively detect the welding quality at the root and inside of the weld, and can also be used to detect the development of existing weld defects, thus determining the importance of surface testing of the weld. Generally, the material of high-pressure tee welds is ferromagnetic material, so magnetic particle flaw detection should be used for surface testing of forged socket tee welds. Another method for detecting the surface of weld seams is dye penetrant testing, which requires the welding waves of the weld seam to be polished smooth before implementation. The dye penetrant testing method is more suitable for detecting the surface of weld seams. 　　In the manufacturing industry of forged three-way pipe fittings, the broad concept of "forging" refers to the production of pipes, plates, and forgings as raw materials, and its manufacturing method includes almost all the forming processes of pipe fittings.

When it comes to specific varieties (including all varieties of socket welding and threaded fittings, branch fittings, and other fittings that require forging, such as thick walled forged tees), the so-called "forging" refers to fittings that are mainly formed by forging. The content mentioned here refers to the latter type of forging. 　　Hydraulic bulging of tees is a forming process that uses axial compensation of metal materials to expand branch pipes. The process involves using a dedicated hydraulic press to inject liquid into a tube blank with a diameter equal to that of the tee, and synchronously moving the two horizontal side cylinders of the hydraulic press to compress the tube blank. After the tube blank is compressed, its volume decreases, and the pressure of the liquid inside the tube blank increases as the volume of the tube blank decreases. When the pressure required for the tee branch pipe to expand is reached, the metal material flows along the mold cavity under the dual action of the side cylinder and the liquid pressure inside the tube blank to expand the branch pipe. 　　Forging tee manufacturer 　　The hydraulic bulging process of three-way can be formed in one go, with high production efficiency; The thickness of the supervisor and shoulder wall of the three-way joint has increased.
