【Major Chemical Equipment】437~2022: 3.5Ni steel with a maximum thickness of 160 millimeters

To promote the localization of 3.5Ni steel plates, in 2010, Hegang Wugang took the lead in developing such steel. The products, which were evaluated by **-level institutions, had a thickness of 150 millimeters – the highest thickness available at that time, both domestically and internationally. Their key technical parameters were at the world’s leading level, enabling them to replace imported products and fill a gap in the domestic market. China’s key projects, including the world’s first 3000-cubic-meter ethane sphere tank made from 3.5Ni steel, and the country’s largest shift gas methanol absorption tower, have all utilized 3.5Ni steel developed and produced by HBIS Wugang. In recent years, HBIS has relied on technological innovation and upgrades to drive the optimization of its \"two structures,\" increased efforts in the research and development of Ni-series steels, and continued to create high-performance products that serve as benchmarks, thereby leading the industry forward. Hebei Iron and Steel Wugang keeps pace with the development direction of Hebei Iron and Steel, leverages its advantage of having R&D capabilities for 3.5Ni steel at an internationally advanced level, promotes the development of new varieties of 3.5Ni steel, and continuously meets the differentiated needs of its customers. In response to the customer’s specific requirements – that the thickness of the required product exceeded the standard by 10 millimeters, and that the impact strength at 1/2 of the steel plate thickness was nearly three times higher than that of domestic Q235 carbon structural steel – a dedicated technical team was formed to develop customized product solutions for the customer. In light of the fact that as the thickness of the steel plate increases, the technical challenges associated with ensuring its performance also rise exponentially, extensive discussions were held on multiple occasions with the American Shipbuilding Association. Efforts were made to upgrade technologies and develop innovative design solutions; two new technological innovations were introduced. By exceeding international standards in terms of various technical parameters, the delivery time was reduced by at least 15 days, which won the approval of customers and secured an exclusive supply contract for steel used in the construction of secondary gas washing towers for foreign projects.

It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ----------------------------------------------The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, 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 – let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------【Ministry of Emergency Management’s Special Inspection 2022】Summary Edition – Feel free to participate in discussions and self-inspections! ! ! ! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=3418729 (Source: Huahai Chuanliu – Haichuan Network) Summary post for the 【Major Chemical Equipment in China】 series; being updated. https://bbs.hcbbs.com/thread-3366481-1-1.html (Source: Huahai Chuanliu – Haichuan Network)
