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 greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ===================== Recently, the overall core insertion of a super-large heat exchanger tube bundle – that is, the insertion of the tube bundle into the shell – undertaken by a domestic pressure vessel manufacturer was successfully completed. Daming supplied 26 tube bundle baffle plates and 2 tube sheet plates for this project. ■It is understood that this super-large heat exchanger will be used in a project carried out by Dow Chemical in the United States. It was designed and manufactured in accordance with ASME standards; its diameter is approximately 5.2 meters, the total length of the equipment is about 42 meters, and its total weight is 800 tons. The tube bundle section alone is 28.9 meters long and weighs over 440 tons. The equipment housing is large in diameter and length, and requires high precision; factors such as the roundness and straightness of the housing during manufacturing, as well as any deformation that may occur when the equipment is in a horizontal position, all have a direct impact on whether the equipment can successfully pass through the core. ■Jiangsu Daming and Daming Heavy Industry provided the complete set of tube bundles, baffle plates, and tube sheets for this equipment, involving multiple processing steps such as material selection, cutting, edge trimming, turning, straightening, deep hole drilling, and fitting work. Among them, the baffle is made of 316L material, while the tube sheet is fabricated from 304, 16Mn, and composite materials, available in a wide range of specifications. To date, Daming has supplied over 1,000 tons of supporting products such as tube sheets, baffle plates, and flanges to this pressure vessel manufacturer. Luming takes advantage of its capabilities in \"coherent and customized\" processing to provide customers with efficient, high-quality, cost-effective manufacturing services, which has earned it high recognition from clients.
