【Major Equipment in the Chemical Equipment Industry】Domestic production of the key valve for LNG receiving stations – the “LNG cryogenic 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 discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** On September 8-9, 2021, the China General Machinery Industry Association and Kunlun Energy Co., Ltd. organized a meeting in Chongqing to evaluate the domestically developed prototype of the \"LNG cryogenic ball valve\", a key valve used in LNG receiving stations and designed and developed by Chongqing CHUANYI Control Valve Co., Ltd. Users such as CNOOC and Guangdong Zhuhai Jinwan LNG attended the meeting. With the successful appraisal of the prototype of Chuanyi Control Valves’ “LNG cryogenic ball valve,” Chuanyi Control Valves has become the first domestic manufacturer to have its LNG ultra-low temperature control valves, LNG ultra-low temperature ball valves, and LNG ultra-low temperature butterfly valves all pass the appraisal by the China Valve Industry Association. This provides a comprehensive solution for low-temperature applications, marking a significant step forward for Chuanyi Control Valves in the effort to achieve domestic production as a substitute for imported LNG ultra-low temperature valves. The domestic production project for low-temperature valves at LNG receiving stations was a project undertaken by Chongqing Chuanyi Control Valves in 2018, focusing on the development of three types of valves. Through the efforts of researchers, the products developed have achieved significant breakthroughs in online maintenance and the design of compensation structures at -196°C. They meet all the requirements of the British BS6364 standard as verified by comprehensive performance tests, and they are the only low-temperature ball valves in China to be used in operational settings.

Meanwhile, in 2018, Chuanyi Control Valves also undertook the 40 million tons per year integrated refining and chemical project at Zhejiang Petrochemical, providing complete sets of valve solutions for 28 main units, including those related to crude oil storage and transportation systems, jet fuel hydrogenation, diesel hydrocracking, wax oil hydrogenation, residue hydrogenation, and catalytic gasoline hydrogenation. In particular, key technical challenges were overcome in terms of critical manufacturing processes, including corrosion resistance of components, sealing using special fillers, high leakage resistance, and anti-salt spray painting for use in marine and aerial environments. As a result, the core competitiveness of these products has been enhanced, enabling them to replace imported alternatives.
