Shenhua Ordos Coal Liquefaction Plant
Heating furnace outlet shut-off valve
Shenhua Group Erdos Coal to Oil Branch has a completely independently developed and internationally leading coal direct liquefaction process. Imported metal sealed ball valves from the United States were initially used in important high-temperature and high-pressure hydrogen working conditions. Against the backdrop of vigorously promoting the localization of important imported equipment in China, the imported metal sealed ball valve is not only expensive and has a long supply cycle, but also constantly exposes small problems during use. Therefore, leaders at all levels of Shenhua Group Erdos Coal to Oil Branch attach great importance to the localization research of this valve, and it is particularly important to choose a valve enterprise that can undertake this responsibility. In 2012, Shenhua Group Erdos Coal to Oil Branch organized dozens of top experts in the valve industry to conduct a comprehensive evaluation of a few domestic valve enterprises with the production and research capabilities of this valve. Newjing Company won with complete on-site first-hand working condition data, a strong expert R&D team, years of accumulated rich experience in the production and use of metal sealed ball valves, advanced processing and manufacturing technology, and perfect inspection methods. Shenhua Group Erdos Coal to Oil Branch ultimately chose Shanghai Newjing Valve Company to conduct research and production on the localization of this valve, and was supervised throughout the process by Hefei General Machinery Research Institute.

Shanghai Petrochemical S-Zorb gasoline adsorption desulfurization unit
Shanghai Petrochemical - Refining Department (Design and Manufacturing)
The adsorbent used in the 1.5 million tons/year catalytic gasoline adsorption desulfurization (S-ZORB) unit of Sinopec Shanghai Petrochemical Co., Ltd. was originally a GOSCO imported wear-resistant ball valve. Due to the high hardness alumina particle catalyst used in this working condition, the switch frequency is frequent (once every 20 minutes), and the operating temperature is as high as 440 ℃. After three months of use, a series of serious problems that threaten the safety of the unit occur, such as action jamming, sealing surface scratches or erosion, poor sealing, valve stem deformation, ball or valve seat erosion or even penetration, and cavity erosion. For this purpose, after sufficient technical exchanges between the Refining Department of Shanghai Petrochemical Co., Ltd. and Shanghai Newjing Company, Newjing Company's high hardness diamond surface treatment and 360 degree mirror matching grinding technology were used to repair the valve seat and sphere of the imported valve.
