Looking at the ten-year development of chemical technology, I praise the prosperity and strength of modern China. This is just a starting point to encourage further discussion – more participation will make it even more lively. With you here, HaiChuan becomes even better. [Ten Years of Progress in Chemical Equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Happy National Day! ! ! , ----------------------------------------- CNOOC Bohai Petroleum Equipment Manufacturing Co., Ltd.’s Lanzhou Petroleum and Chemical Equipment Company is located in Xigu District, Lanzhou City, Gansu Province; the factory covers an area of approximately 12,000,000 square meters. The company was established in 1956 as part of the Lanzhou Refinery, a key project under China’s First Five-Year Plan. On March 30, 2010, the Lanzhou Petrochemical Equipment Company was transferred from CNPC Lanzhou Petrochemical Company to CNPC Bohai Petroleum Equipment Manufacturing Co., Ltd. The main products of this company include FCCU flue gas turbines, high-temperature special valves along with their associated actuators, DCU hydraulic desulfurization systems, DCU bottom and top valves, as well as gas turbines. The specifications of its gas turbines range from 2000KW to 33,000KW; it is the manufacturer with the highest number of units sold worldwide, and its technical level is at the international advanced stage. High-temperature specialty valves include five major categories such as slide valves, plug valves, butterfly valves, gate valves, and actuators, with nearly 600 different models available. They are primarily used in the harsh operating conditions of the petrochemical industry, but can also be applied in industries such as coal chemistry and metallurgy. Lanzhou Petrochemical Equipment Company has won the trust of numerous customers thanks to its cutting-edge technology, reliable performance, excellent quality, and attentive service. Since developing China’s first high-temperature slide valve in 1964, through continuous efforts, the technical level of its various products has reached the leading standard in the country. The company’s products are marketed in 28 provinces, municipalities, and autonomous regions across China, and its products and services serve nearly 200 domestic refining and chemical enterprises. It also exports to various countries in Asia, Africa, and Europe, including Russia, Kazakhstan, Kyrgyzstan, **, Malaysia, Sudan, Algeria, Niger, Chad, and others. The cold-wall slide valves for Russian projects are key equipment in petrochemical plants, and foreign clients require that they be designed and manufactured in strict accordance with the standards and specifications of the American Society of Mechanical Engineers (ASME). Faced with the extensive ASME standard framework, the company’s designers carefully studied the relevant English standards and translated each technical requirement into practical elements in the design of the slide valves. ASME standards and codes were strictly followed in all aspects, including valve structure design, selection of raw materials, the design and construction of linings and welding procedures, as well as the establishment of non-destructive testing standards, requirements for heat treatment and hot-state testing, and the packaging and transportation of the complete units. The company strengthens the operation of its quality assurance system; every single component, from large items such as valve bodies and valve covers to small parts like bolts and nuts, is properly labeled and assigned to specific individuals, thereby ensuring product quality and traceability throughout the production process. In March 2021, two ASME-standard cold-wall slide valves were loaded and shipped from Lanzhou on their way to Russia; this marked the first time that products from our petrochemical equipment company entered the European market, representing another solid step forward in our efforts to expand in international markets.
