Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to join in the forum discussions. The fragrance of rice flowers in August ----------------------------------------- The world’s first new energy steel pipe production line featuring both spiral and straight-seam welding techniques, with a length of 18.3 meters, was officially completed and put into operation at CNPC Baoshi Shun (Qinhuangdao) Steel Pipe Co., Ltd. This project fills a gap in the field of new energy welded pipes in China, and will provide strong support for the transmission of new energy sources such as hydrogen, as well as for the construction of pipelines for major energy projects. The project was funded by CNPC Baoji Petroleum Pipe Co., Ltd., with its wholly-owned subsidiary, CNPC Baoshi Shun (Qinhuangdao) Pipe Co., Ltd., responsible for its construction. From the start of construction to completion and operation, it took only 14 months, which is 10 months shorter than the usual construction period, thus creating the \"Qinhuangdao Speed\". This project has achieved two world firsts: it is the world’s first production line to utilize both straight-seam and spiral welding processes, and its core equipment is manufactured using the world’s first 18.3-meter die-type forming machine. Four firsts in China were achieved: the first 18.3-meter JCOE (straight-seam double-sided submerged arc welded pipe) production line, the first welded pipe production line in a 3D digital factory built using digital twin technology, the first production line that enables automated centralized control of straight-seam forming and precision welding, and the first production line where straight-seam precision welding is carried out at the same workstation. The project also fills a technical gap in the industry by achieving 100% coverage for both board inspection and pipe end inspection. Furthermore, the new production line makes extensive use of new technologies for the first time, **enhancing its digitalization capabilities. CNPC Baoshishun (Qinhuangdao) Steel Pipe Co., Ltd. is one of the leading enterprises in the major equipment manufacturing sector in Qinhuangdao. To date, it has supplied over 4 million tons of high-quality steel pipes for various domestic pipeline projects, and exported nearly 1 million tons of such pipes to foreign countries.
