Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for 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 greater 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! ****************** In 2017, Ansteel produced the world’s widest ultra-wide pressure vessel steel plates, with a length of over 5 meters. The steel used for these ultra-wide pressure vessels supplied by Ansteel had high levels of Cr and Mo alloys, and it required normalizing followed by tempering treatment. At the same time, these contracts impose extremely strict requirements on parameters such as the sheet shape of the products and their performance, exceeding the current production and design capabilities of heat treatment processes in the industry. Not only that, but it is also necessary to meet the performance requirements for stress-relief heat treatment after tube manufacturing, which poses a great technical challenge. By successfully overcoming the key technologies involved in the production of CrMo steel plates for ultra-wide pressure vessels, Ansteel has not only enhanced its capacity to manufacture steel plates of such ultra-wide specifications but also **improved the safety of pipelines used in the petrochemical industry. This advancement contributes to the development of equipment in China’s petrochemical sector, providing strong support for the advancement of high-end manufacturing of CrMo steel plates for ultra-wide pressure vessels in China, as well as for enhancing its market leadership and share. To meet customer demands and ensure that products are delivered on time with guaranteed quality, the Product Development Department of Ansteel Co., Ltd. worked closely with teams involved in production, sales, and research, including the Heavy Plate Department of Ansteel’s Bayuquan Branch, Ansteel Group’s Iron and Steel Research Institute, and Ansteel Co., Ltd.’s Medium-Heavy Plate Marketing (Service) Center. By leveraging their extensive technical expertise and advanced manufacturing equipment, they overcame challenges in various production processes, pushed beyond limits, and broke conventional boundaries to solve a range of production and technical issues. As a result, they successfully developed a mature and stable full-process production technology for rolling control and heat treatment of ultra-wide steel plates with a width of over 5 meters. The produced steel plates feature precise dimensions, good shape, and uniform properties, ensuring stable performance after heat treatment for tube manufacturing by users. It is understood that the remaining contracts are being accelerated, with delivery expected to be completed by the end of the year.
