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.
