【Major Industrial Equipment in the Chemical Industry】075-56″ Class900 High-Pressure, Large-Diameter Fully Welded Ball Valve
Thread Content
The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! *********************************** On April 8, 2021, the China National Machinery Industry Federation and the China General Machinery Industry Association held in Chengdu a product appraisal meeting for the 56″ Class900 high-pressure, large-diameter fully welded ball valve developed by Sichuan Jingkong Valve Manufacturing Co., Ltd. The \"56\" Class 900 high-pressure, large-diameter fully welded ball valve\" developed by Sichuan Jingkong Valve Manufacturing Co., Ltd. possesses independent intellectual property rights. Its key performance indicators are at the advanced level of similar products both domestically and internationally, making it suitable for widespread use.
The 48-inch electric fully welded ball valves put into production by Su Yan Group in 2018 can, according to the engineers here, be used to connect oil pipelines with a diameter of 1.2 meters, and the manufacturing cost of each such valve exceeds 1 million yuan. Currently, there are only a few companies in the country capable of producing such ultra-large diameter ball valves.
From July 9 to 11, 2019, during the industrial tests simulating severe operating conditions conducted at the domestic valve testing facility of the Yandun Compressor Station on CNPC’s Western Pipeline, the 56″ Class900 high-pressure, large-diameter fully welded ball valve prototype developed by Suzhou Newway Valve Co., Ltd. successfully passed all the tests specified in the \"Industrial Field Test Outline for the Development and Application of Oil and Gas Pipeline Valves – 56″ Class900 Fully Welded Valves\" on the first attempt.
In October 2018, Suzhou Newway Valves initiated independent research and development on a prototype of a 56″ Class900 high-pressure, large-diameter fully welded ball valve. All performance tests for this prototype were completed in April 2019. In May, it passed the evaluation of product prototypes at the level organized by the China Machinery Industry Federation and the China General Machinery Industry Association. In July, it succeeded in the industrial-scale tests conducted at the domestic valve testing facility at the Yandun Compressor Station of the Western Pipeline Project. The entire process took only 9 months, which clearly demonstrates the strong R&D capabilities, production capabilities, supply assurance capabilities, process control capabilities, testing and inspection capabilities, as well as quality assurance capabilities of Suzhou Newway Valves Co., Ltd. As one of the leading suppliers of valves for domestic long-distance pipelines, Neway Valves will continue to play its part in promoting the localization of ultra-large ball valves for such pipelines in China.
