Recently, SXYG Steel Pipe Technology Group, a leading manufacturer of titanium alloy tubing and high alloy coiled tubing seamless steel pipes for oil wells in China, announced:
The company has just completed the first full-scale physical HFW welded pipe high-pressure long-term hydrogen charging test in China, marking a new breakthrough in the company's major project of "research and product development of new energy pipe technology and equipment such as hydrogen, CCUS, and geothermal".
Hydrogen energy is a strategic energy source, and pipeline hydrogen transmission is one of the most economical and efficient methods for large-scale and long-distance hydrogen energy transmission.
Currently, the highest steel grade of pure hydrogen transmission pipelines in service in China does not exceed X42 steel grade, and the maximum transmission pressure does not exceed 6 MPa. They are mainly made of seamless pipes.
In order to further expand the application scope of the company's products in the field of pure hydrogen transportation, SXYG successfully completed a 6.3 MPa high-pressure long cycle hydrogen charging test using the previously developed X52 steel grade HFW welded pipe for pure hydrogen transportation.
It is reported that prior to this test, the HFW welded pipe developed by SXYG for pure hydrogen transportation has successfully passed third-party physical and chemical properties and environmental adaptability assessments for high-pressure pure hydrogen, and the environmental suitability assessment results for high-pressure pure hydrogen are superior to seamless pipe products of the same steel grade, filling the gap in the company's welded pipe products for high-pressure pure hydrogen transportation.
The successful completion of this test has verified the safety and reliability of the HFW welded pipe product of SXYG Company in service under actual pure hydrogen transportation conditions, indicating that the product can meet the requirements for high-pressure hydrogen transportation with an annual throughput of 100,000 tons or more.
