【Ten Years of Rapid Development in Chemical Engineering Equipment】906–2023: Baoji Steel Pipe Manufacturing’s 457-mm-diameter Baotou-Linhe hydrogen-infused pipeline
Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you all; we welcome everyone to join in the forum discussions. Happy May Day! A safe and secure Red May ********************************************* On March 19, Baoji Steel Pipe Baoshiwei Company produced over 4,100 tons of spiral welded pipes with a diameter of 457 millimeters and a wall thickness of 8.8 millimeters for the Baotou-Linhe hydrogen transport pipeline; the quality of these products as well as the efficiency of supply guarantee were highly recognized by customers. This is also an innovative move by the company to break through the \"forbidden zones\" in the field of hydrogen transportation. “The utilization of hydrogen energy is a **strategy** for green development. When transporting hydrogen through pipelines, the high permeability of hydrogen molecules through metals causes the pipelines to be prone to hydrogen embrittlement fractures, which severely limits the utilization of hydrogen energy. ”Liu Bin, a senior engineer at Baoji Steel Pipe, told reporters, “The company’s ability to undertake the construction of hydrogen transmission pipelines with a 10% hydrogen content is the result of technological innovation.” ” In recent years, Baoji Steel Pipe has actively participated in the drafting of the \"Design Code for Hydrogen Pipeline Engineering\". This standard was officially released and put into effect at the beginning of this year, providing technical guidelines for the design of hydrogen pipeline projects in China. At the same time, Baoji Steel Pipe continues to increase its efforts in the research and development of new energy pipes, carrying out systematic studies on pipe design, welding, shaping, testing, and other aspects. At present, the company has successfully developed spiral hydrogen-doped welded pipes and straight-seam welded pipes for pure hydrogen transportation. Test results show that they exhibit excellent resistance to hydrogen embrittlement, ranking among the best in this category of pipes currently available. “From participating in the formulation of standards, to tackling the core technologies related to hydrogen transport pipelines, to their industrial application, we have always been at the forefront of the industry chain. ”As introduced by the company’s lead technical expert, Bi Zongyue. It is reported that at the beginning of this year, the company affiliated with Baoji Steel Pipe undertook the production of pipes with hydrogen mixed in them on a large scale. It also completed the trial production of straight-seam pipes for transporting pure hydrogen, thereby mastering the key technologies involved in manufacturing hydrogen transport pipes and laying a technical foundation for ensuring the supply of various high-end new energy pipes.

This project is the first long-distance high-pressure pipeline in China to have the capability for transporting hydrogen, funded and constructed by Western Gas Company. It is a key natural gas infrastructure project in the autonomous region, as well as a major project under the petrochemical and natural gas pipeline construction plan for the 14th Five-Year Plan period in Inner Mongolia Autonomous Region. The total investment in this project is 910 million yuan. The construction starts in Jiuyuan District of Baotou City, passes through Wulat Qianqi and Wuyuan County in Bayannur City, and finally reaches Linhe District. The total length of the pipeline is 258 kilometers, of which 235 kilometers are main pipelines and 23 kilometers are branch pipelines. The designed pressure of the pipelines is 6.3 megapascals. There are 10 valve rooms and 3 stations along the entire route, and the maximum gas transmission capacity can reach 1.2 billion cubic meters per year. Completion and operation are expected by the end of this year. The construction of this project will enable effective connection between the Changqing-Hohhot double-line gas pipeline and the Changqing-Wuhai-Linhe gas pipeline operated by Western Natural Gas Company, thus achieving interconnection of gas pipelines in the central and western regions of Inner Mongolia. It will meet the gas supply needs of industrial users in Bayannur City, Baotou City, and Wuhai City, as well as those in the associated counties and districts, helping to reduce the energy costs for enterprises. It will also ensure a safe, continuous, and stable supply of gas in the areas surrounding these pipelines. Furthermore, it will play an important role in promoting the adjustment and optimization of the regional energy structure, facilitating the transition to new forms of energy, and improving the regional air quality.
