目前,国内的输氢管道工程经验相对较少,且输氢管道材料多为低压低钢级管材,在掺氢天然气输送管道材料的设计和适用性评价方面还没有形成统一的认识。通过国内外输氢管道及储氢容器的相关标准及规范调研,重点梳理了输氢环境中管材性能的相关要求及适用性评价方法。针对不同标准中提出的管材拉伸性能、断裂韧性、疲劳性能和紧固圆盘爆破压力等关键性能指标,对比分析了各标准中测试方法的差异,并结合相关测试数据,总结了目前在含氢环境中管道适用性测试评价标准的不足。

At present, there are relatively few domestic hydrogen pipeline engineering experience, and most of the hydrogen pipeline materials are low-pressure and low-grade steel pipes. There is no unified understanding of the design and applicability evaluation of hydrogen-doped natural gas transport pipeline materials. Through the investigation of relevant standards and specifications of hydrogen transmission pipeline and hydrogen storage container at home and abroad, the relevant requirements and applicability evaluation methods of pipe performance in hydrogen transmission environment are sorted out. Aiming at the key performance indexes such as tensile properties, fracture toughness, fatigue properties and burst pressure of fastening discs in different standards, the differences of test methods in each standard are compared and analyzed, and the shortcomings of current test and evaluation standards for pipeline suitability in hydrogen-containing environment are summarized in combination with relevant test datas.
