【Ten Years of Rapid Development in Chemical Processing Equipment】The First 40\" 1500LB Fully Welded Emergency Shut-Off Valve from 1061 to 2021

Thread Content

Ten years of rapid development in chemical engineering technology – 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 take an active part in the forum discussions. Be careful with fire risks as the heat increases in July. --------------------------------------------- Following the successful delivery of the first set of 32\" 1500LB fully welded ball valves to a key project of Sinopec in September 2019, the R&D team at Neway continued to work hard. Drawing on valuable first-hand experience in research and application, and leveraging the design and manufacturing strengths of both China and Italy, they managed to develop the 40\" 1500LB fully welded ball valve technology after two years of effort. In September 2021, they delivered the first set of domestically produced 40\" 1500LB fully welded emergency shut-off ball valves to a key project in the pipeline network; two more batches of valves of the same specification are currently in production. These valves not only feature a high design pressure and large channel dimensions, but also need to meet requirements for long-term maintenance-free operation and emergency shut-off; this imposes extremely high quality standards on both the valves themselves and their automatic control systems. Faced with this challenging task, the R&D teams at Newway China worked closely together; they conducted numerous theoretical calculations and experimental tests on the structure and material selection of the key components. High-precision machine tools and new manufacturing processes were used for welding and processing. In addition, the valves were equipped with pneumatic control systems and intelligent diagnostic modules that meet SIL3 standards. As a result, the valves passed all functional tests on the first attempt, thus filling the gap in domestic production of large-diameter, high-pressure fully welded ball valves.
