Red May for chemical industry workers! Reply reward! ---------------------------------------------- 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 localization of such equipment. We invite everyone to share their insights and discuss these topics together, to cheer for Made in China and to support the development of chemical processing equipment! ===================== In May 2021, within the production facilities of China National Heavy Machinery Corporation, amid the rhythmic humming of the presses, the world’s first fully austenitic stainless steel die-forged main pump casing was successfully manufactured, with on-site supervision by various organizations including the North China Nuclear Radiation Safety Supervision Station of the Nuclear Safety Administration and the Nuclear and Radiation Safety Center. This marked significant progress in the joint development project carried out by China National Heavy Machinery Corporation and Hebei Hongrun Nuclear Equipment Co., Ltd. The successful trial production of die-forged pump casings not only resolved the long-standing problem of poor quality in cast pump casings, but also utilized die-forging to minimize the amount of forging waste and preserve the forging fiber structure. This approach ensured the mechanical properties of the forgings while enabling near-net shaping and green manufacturing of ultra-large forgings, reflecting a high level of technical expertise in China’s large-scale forging industry. It also provided valuable experience for the design of ultra-large multi-functional presses by China National Heavy Machinery Corporation.
