Ten years of rapid development in chemical processing equipment – praise for the prosperous and strong China. 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 join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* From June 1st to 2nd, 2023, the China National Machinery Industry Federation and the China General Machinery Industry Association organized a review meeting in Suzhou for the products “High-temperature and high-pressure material distribution plunger valves for direct coal liquefaction systems” and “Multi-stage pressure reduction control valves for direct coal liquefaction systems”. These products were developed jointly by the Ordos Coal-to-Oil Branch of China Shenhua Coal-to-Oil Chemical Co., Ltd. and CNNC Su Valve Technology & Industry Co., Ltd. The review meeting was chaired jointly by the China National Machinery Industry Federation and the China General Machinery Industry Association. The expert panel of the appraisal committee is composed of experts from Hefei General Machinery Research Institute Co., Ltd., the Coal Direct Liquefaction **Engineering Research Center, Sinopec Engineering Construction Co., Ltd., Sinopec Luoyang Engineering Co., Ltd., Inner Mongolia Yitai Group Co., Ltd., China Chengda Engineering Co., Ltd., the School of Mechanical and Power Engineering at Shanghai Jiao Tong University, Wenzhou Research Institute of Zhejiang University, and PetroChina East China Design Institute Co., Ltd., among other institutions. “The \"High-temperature and High-pressure Material Distribution Plunger Valve for Coal Direct Liquefaction Units\" (specifications: Class 2500, DN450×DN350) is an important valve in coal direct liquefaction plants with a production capacity of millions of tons. This valve features a five-way design with one inlet and four outlets; its body is forged as a single unit, giving it wear resistance, erosion resistance, and resistance to coking. “The multi-stage pressure-reducing control valves for direct coal liquefaction (control valves for high flow rates, high temperature and pressure differences with low solid content, control valves for low flow rates, high pressure differences and low solid content, and control valves for high pressure differences in the presence of acidic water-corrosive media) feature a multi-stage pressure-reducing structure, enabling stable flow regulation; moreover, these valves are resistant to wear and erosion.
