【Ten Years of Rapid Development in Chemical Engineering Equipment】Paoji Steel Pipe’s trial production of 508-mm-diameter straight-seam welded hydrogen transport pipes in single furnaces, 1990–2023

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 engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* On February 22, 2023, Baoji Steel Pipe Baoshishun Company carried out a pilot production run using a single furnace to manufacture straight-seam welded hydrogen transport pipes with a diameter of 508 millimeters. Inspections for defects and visual checks showed that the quality of these pipes met the required standards, thereby providing the technical foundation needed for the future production of pipes used in new energy applications. Against the backdrop of the **\"dual carbon\" goals, Baoshi Shun Company actively collaborated with the Management Research Center to carry out this trial production of hydrogen transport pipes. During the preliminary stage of prototyping, both parties analyzed the properties and chemical composition of the raw materials, and had in-depth discussions on details such as the forming and expansion process, the selection of welding materials and welding parameters, as well as production sampling. During the trial production process, the technical staff at the straight-seam factory monitored the process tuning throughout the entire period, addressing any issues that arose promptly. The personnel on duty carefully checked and measured the parameters for each processing step in accordance with the specified requirements, and the offline inspection results met the standard criteria, enabling the successful completion of the trial production. Next, Baoshishun Company will build on this trial production to actively explore new technologies, develop new products, strive to expand into new market segments, and make technical and product preparations to gain a foothold in the high-end market for conveyor pipes.
