Gemstone Tubing achieves commercialization of pure hydrogen pipes for the first time

Thread Content

On August 5, the straight-seam submerged arc welded pipes for transporting pure hydrogen, produced by Qinhuangdao Baoshishun Company under Gemstone Pipe Industry, as part of China’s first cross-provincial, long-distance, large-scale green hydrogen pipeline project, were undergoing pre-shipment visual inspections ahead of their shipment to the construction site. This marks a major breakthrough for Gemstone Tubing in the commercial application of pure hydrogen pipes, providing a solution for the large-scale transportation of green hydrogen. Against the backdrop of the global energy transition, Gemstone Pipe Industry established a professional R&D team in 2022 to work together with hydrogen industry users, steel manufacturers, universities, research institutions, and pipeline design firms to tackle technical challenges. In response to the specific requirements in the field of hydrogen transportation, the R&D team overcame numerous challenges related to hydrogen storage and transportation technologies. They successfully developed straight-seam submerged arc welded pipes for pure hydrogen transportation that possess independent intellectual property rights, thereby filling a gap in China’s hydrogen transportation product portfolio. This achievement has made Bao Shi Pipe Industry one of the companies in China with the widest range of steel grades, the most diverse specifications, and the most complete product lineup in the field of hydrogen transportation pipes. In addition, Gemstone Pipe Industry took the lead in formulating the group standard \"Evaluation Regulations for Hydrogen Long-Distance Transmission Pipelines,\" filling a gap in the field of hydrogen pipeline evaluation in China and providing unified standards for the research, development, and production of hydrogen transmission pipelines. The new straight-seam submerged arc welded pipe for hydrogen transport, developed and manufactured by Gemstone Pipe Industry, features ultra-high purity and extremely fine grain structure, which effectively reduces the risk of hydrogen embrittlement and ensures long-term stable operation in high-pressure hydrogen environments, thus laying a technical foundation for its commercial application. The acceptance of this order signifies that Gemstone Pipe Industry’s technical expertise in the field of new energy pipes has been recognized by the market.
