Comply with the Work Safety Law! Take on the role of primary responsible person! ---------------------------------------------- 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. 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 welcome everyone to share their insights and engage in discussions; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ On the morning of June 21, 2022, the nitric acid absorption tower – the tallest and heaviest piece of equipment in Shandong Haihua Group’s nitrate project – was lifted into place, laying a solid foundation for the progress of the project according to the planned schedule. This equipment lifting task is highly challenging. The nitric acid absorption tower has a diameter of 3.4 meters and a net height of 57.2 meters; its total lifting weight is 167 tons. The weight and height of this equipment have set new records for equipment lifting by marine engineering companies. It took the employees of the Marine Construction Machinery Manufacturing Branch 3 months to overcome various challenges such as the large diameter of the equipment, its complex structure, and limited welding space. After conducting on-site pressure tests, they used the self-made equipment to carry out heavy-duty repairs, thus completing the most technically challenging equipment refurbishment in the company’s history.
