Bohai Equipment accelerates the customization of the first batch of 28-mm ultra-thick large-diameter spiral steel pipes to support the construction of the \"Han-to-Wei Water Transfer Project\"

Thread Content

Recently, the first batch of 28-mm ultra-thick large-diameter spiral steel pipes, custom-made by Bohai Equipment Huayou Steel Pipe Company for the major water infrastructure project \"Yinhan Jiwei\", have been put into full production at an accelerated pace, providing essential pipe materials for the construction of this project. 01**Strategic Project: Diverting Water from the Han River to the Wei River to Quench the Thirst of Guanzhong for Thousands of Years. The “Diverting Water from the Han River to the Wei River” project is a major strategic water resource allocation initiative located in Shaanxi Province; it serves as an important complement to the South-to-North Water Diversion Project. The core idea is to transfer water from the Han River, a tributary of the Yangtze River where water resources are relatively abundant, to the Wei River, the largest tributary of the Yellow River, thereby addressing the water shortage in the Guanzhong region. This approach is of great significance for ensuring water security and promoting coordinated regional development. 02 Corporate Responsibility: Bohai Equipment Overcomes the Challenge of \"Extra-Thick\" Pipes. Thanks to its advantages in product quality, technical expertise, and service capabilities, Bohai Equipment’s Huayou Steel Pipe Company was entrusted with supplying 50% of the steel pipes needed for the Xianyang section of this project. To address the manufacturing challenges posed by 28-mm ultra-thick large-diameter steel pipes, repeated tests were conducted to optimize key aspects such as the forming of thick-walled steel pipes and the control of welding quality. By improving the parameters of the forming equipment and increasing the frequency of online inspections, issues such as irregular shaping and unstable weld quality that often occur in the production of thick-walled steel pipes were effectively resolved, ensuring a smooth production process and consistent product quality.
