China's first group standard for stainless steel pipes for hydrogen energy, stainless Steel Seamless Pipes for Hydrogen Energy Vehicles, has been officially released on the National Group Standard Information Platform and will come into effect on October 1, 2021.
The stainless steel seamless tube with corrosion resistance and high pressure resistance is very important for the filling, storage, transportation and use of hydrogen energy vehicles. However, there is no complete national and industrial standards in China before this, which makes the quality of stainless steel tubes used in hydrogen energy vehicles uneven, which has laid a huge hidden danger for the market and life and property safety.
The release of "Stainless steel seamless pipe for Hydrogen Energy Vehicle Pipelines" (hereinafter referred to as the "Standard") has brought a glimmer of hope. The "Standard" clearly standardized the classification, size, shape, weight, technical requirements, test methods and inspection rules of stainless steel seamless pipes for hydrogen energy vehicle pipelines, and also focused on adding special requirements for steel pipe smelting method, purity, corrosion resistance, hydrogen environment application, etc. And give full consideration to the domestic and foreign automobile pipe with stainless steel seamless tube production condition, equipment manufacturers, the use of actual production, and test ability, etc., absorb the development of the steel pipe at home and abroad in recent years, makes every effort to: practical, correct, complete, and is rigorous, the indicators and the industry at home and abroad advanced technology norms, enough to reach the international advanced level.
"Standard" put forward by Shanghai steel tube industry associations and centrally, ma on shan statue of horse shun technology co., LTD. And Shanghai huaxin energy systems co., LTD., responsible for drafting, bao wu special metallurgy co., LTD., Shanghai jie hydrogen technology co., LTD., Shanghai's automobile co., LTD., dalian boiler pressure vessel inspection and testing research institute co., LTD., participate in drafting, after half a year, 39, Final approval for release.
