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! ===================== On April 22, the Wuhan Branch of China Classification Society held a ceremony to award factory approval certificates for a range of products made from high-manganese austenitic low-temperature steel (hereinafter referred to as high-manganese steel). Factory approval certificates were issued to HBIS’ high-manganese steel plates, making HBIS the first company in China and the second in the world to receive such certification from China Classification Society for its high-manganese steel products. This marks a significant breakthrough in the research, development, and innovation of high-manganese steel plates in China, as well as a crucial step forward in the localization of high-manganese steel materials for LNG storage tanks.

Manganese steel is one of the key materials used in the manufacture of LNG containers. Compared with 9Ni steel, which is used in conventional LNG storage containers, it enables a significant reduction in manufacturing costs while still ensuring properties such as low-temperature strength, toughness, and fatigue resistance; thus, it represents the best alternative to the traditional low-temperature materials used in LNG containers. Promoting the research, development, and application of high-performance and low-cost manganese steel materials is of great significance for advancing the development of China’s LNG industry and enhancing its core competitiveness and brand influence in the field of high-end LNG shipbuilding. As one of the largest steel material manufacturers and comprehensive service providers in China, HBIS takes it upon itself to supply the steel needed for major domestic projects, focuses on the high-end market, and strives to develop more products that are the best in their category, the only ones of their kind, or alternatives to imported products. Hebei Iron and Steel Group, in collaboration with entities such as the China Classification Society and the 725th Research Institute of China State Shipbuilding Corporation, has established a multi-party cooperation platform for the research and development of high-manganese steel industries. Together, they have developed technical approaches for the research and application of high-manganese steel in China, overcame a series of technical challenges including the control of the properties of high-manganese steel materials, the development of suitable welding materials, and the manufacturing process for storage tanks. As a result, they have created independent key technologies for the production and application of high-manganese steel, thereby breaking foreign monopolies on the technology related to LNG high-manganese steel plates ； In collaboration with the China Classification Society, it took the lead in formulating the group standard T/SSEA \"High-Manganese Austenitic Steel Plates for Low-Temperature Pressure Vessels\", and participated in the development of the \"Guidelines for the Application of High-Manganese Austenitic Low-Temperature Steels\". These efforts have provided strong support for China to achieve original innovation across the entire industrial chain related to high-manganese steel, from material production to its practical applications. At present, Hebei Iron and Steel has become the first enterprise in China to have the capability to produce steel plates with a maximum thickness of 40 mm, as specified in the IMO guidelines, as well as steel plates with a maximum thickness of 63.5 mm in accordance with American pressure vessel standards. The physical properties of the high-manganese steel plates developed by this company are at an internationally advanced level.
