Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to take an active part in the forum discussions. The fragrance of rice flowers in August ------------------------------------------- On July 27, 2023, a meeting was held at Afa Fluid Control Co., Ltd. (hereinafter referred to as AFA) to initiate efforts to develop electric double-eccentric hemispherical valves for the 300,000 tons per year CHPPO unit in Sinopec’s Zhenhai Base Phase II project. Representatives from Sinopec’s Equipment Department, Sinopec Shanghai Engineering Co., Ltd., Sinopec Zhenhai Refining & Chemical Co., Ltd., Afa Fluid Control Co., Ltd., and Shanghai Zhongshen Technology Co., Ltd. attended the meeting, which was conducted both online via Tencent Meeting and in person. At the meeting, AFA Company presented the key issues of this project (key points and challenges), as well as the progress and plans for research and development ； Project manufacturing cycle ； Information on the procurement of purchased components, etc. Currently, international high-end new material projects are developing rapidly, offering great market prospects; for devices such as CHPPO units, POSM units, POCHP units, and other similar process packages, imported C-type ball valve products are used. Domestic similar products have developed rapidly over the past decade, with their technology gradually catching up to international advanced levels. However, it is currently mainly used in mid-to-low-end applications, and is rarely selected for high-end new material projects such as CHPPO units, POSM units, POCHP units, and other similar process package devices. Although imported products have certain advantages in terms of performance and lifespan, they also have many shortcomings and disadvantages: their prices remain high ； The delivery time for imported products is not only long but also highly variable, making inventory control extremely difficult ； It is difficult to replace accessories; some of them are not available in China and have to be purchased from abroad ； The maintenance cycle is long and more expensive, increasing operating costs. Therefore, breaking the monopoly of imported C-type ball valves on key technologies in the high-end new materials industry is of great significance. To achieve the localization of key equipment for high-end new material projects, break the monopoly of existing imported products, reduce procurement costs, and shorten production cycles, Sinopec Zhenhai Refining & Chemical Co., Ltd. launched a project to localize the electric double-eccentric hemispherical valves (tag numbers MV-20503, MV-20603) (900LB 14\") for the 300,000 tons/year CHPPO plant. AFA Company won the contract for the research and development of this domesticization project through bidding. For many years, AFA Company has been dedicated to the research, development, and design of new products. It has obtained **over 50 patents, including 4 invention patents. Among these, the C-type wear-resistant ball valve is a key product developed by the company for use in harsh operating conditions; it holds an **invention patent and fills a gap in the domestic market. This kick-off meeting marks the official commencement of the project aimed at achieving domestic production of electric double-eccentric C-type ball valves. It is believed that through the joint efforts of all parties, this project will achieve complete success and make a positive contribution to the development of China’s high-end new materials industry.
