Witnessing the decade-long rapid development of chemical processing equipment; praising the prosperity and strength of modern China. Replies will be rewarded – discussions are welcome. ------------------------------------------- In August 2021, the RAH regenerative air heater units, manufactured by the Structural Engineering Division of Daming Heavy Industry, were successfully produced and sent to the Formosa Plastics Industrial Park in Ningbo. This project is an important part of the 600,000 tons per year PDH propane dehydrogenation project carried out by Formosa Plastics Industrial (Ningbo) Co., Ltd., and it was undertaken by Zeeco (one of the world’s largest manufacturers of combustion equipment). The design for this project was done in the United States by Zeeco, while Daming Heavy Industry’s structural engineering department was responsible for all aspects of the process, including the analysis and optimization of the design drawings, procurement, manufacturing, and shipping. The furnace shell has a diameter of 8.5 M, a length of 17.5 M, and weighs 95 tons. To support the site preparation efforts for Formosa Plastics’ expansion, Daming Heavy Industry’s Structural Engineering Division overcame numerous difficulties despite tight delivery deadlines. By leveraging the company’s advantages in materials sourcing, it quickly procured special high-temperature resistant materials from the market, held material pre-inspection meetings on schedule, and received high praise from Zeeco. At the same time, a project-specific team was established to start work with the materials. Under the inspection by Zeeco customers and in the presence of Formosa Plastics, the airtightness tests, paint inspections, and final inspections were successfully completed. The products were then shipped out and sent to the Formosa Plastics terminal in Ningbo, where they will be installed at the project site with the assistance of Formosa Plastics. As the first project carried out through the partnership between Zeeco and Daming, the RAH regenerative air heater project received high praise from the client, marking an important and solid step forward in their cooperation. The client stated that \"the cooperation and communication on this project were very smooth,\" and highly praised Daming’s strength in the heavy industry sector.
