【Ten Years of Rapid Development in Chemical Processing Equipment】The Localization of Large-Diameter, Ultra-High Pressure Metal Rigid-Seal Cut-Off Ball Valves from 1996 to 2021

Thread Content

The chemical processing industry has seen significant development over the past decade; let’s celebrate the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. HaiChuan becomes even better with your involvement – we welcome everyone to join in the discussions on this forum. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* In 2020, Nutok, relying on the “Liaohe Petrochemical Shuangtaizi Gas Storage Facility project”, collaborated with Shengli Heavy Industry Group to carry out joint research and development on domestically produced large-diameter, ultra-high-pressure metal hard-sealed isolation ball valves for use in gas storage facilities. A contract was signed for the supply of such valves for more than 10 sets of main pipelines at the Shuangtaizi Gas Storage Facility. It not only replaces imports but also breaks foreign monopolies, driving the transformation and upgrading of the industry as well as technological progress. On May 26, 2021, the 2021 China International Fluid Machinery Exhibition, organized by the China General Machinery Industry Association, opened at the Shanghai Hongqiao Convention and Exhibition Center. Nutock displayed the country’s first set of 20”*2500Lb top-mounted large-diameter ultra-high pressure metal hard-sealed cut-off ball valves, 20”*26” 300Lb anti-surge valves, 12”*600Lb eccentric rotating valves, and other products; the items shown by Nutock became the focus of attention throughout the exhibition. This ball valve weighs over 40 tons; it represents a breakthrough in the core technology related to this product and has led to the development of domestic intellectual property rights, thereby breaking the long-standing foreign monopoly on large-diameter, ultra-high-pressure metal hard-sealed cut-off ball valves used in gas storage facilities.
