摘　　要：为推动我国掺氢天然气管道的发展,综述了目前含氢气环境下管道钢氢脆的研究成果,总结了温度、压力、掺氢比等运行条件对钢材氢脆的影响,分析了钢材强度、微观组织、氢陷阱等材料性质与管道钢氢脆行为之间的联系,归纳了预防和抑制管道钢氢脆行为的方法。笔者认为,当前亟待解决的科学技术问题包括进一步探究掺氢天然气管道环境下不同运行条件对管道钢氢脆行为的影响规律;确定掺氢天然气管道的安全运行温度、压力、掺氢比等关键参数;建立不同服役条件下掺氢天然气管道输送的安全评价方法,完善掺氢天然气管道与现役管道相容性评价体系;形成掺氢天然气管道的设计规范和相关标准;开展气体抑制剂和阻氢涂层等抗氢脆方法的评价。Hydrogen energy has been vigorously developed in recent years,but excessive transportation and storage costs have become a key issue in restricting the development of hydrogen utilization.Blending H2 into existing natural gas longdistance pipelines is the potential best way to transport hydrogen on a large scale,cost-effectively and efficiently.However,H2 can induce hydrogen embrittlement of pipeline steel,which seriously restricts the safe operation of hydrogen-blended natural gas pipelines.In order to promote the development of hydrogen-blended natural gas pipelines in China,this paper reviews the current research results of hydrogen embrittlement of pipeline steel in hydrogen-containing environment;summarizes the influence of operating conditions such as temperature,pressure,and hydrogen blending ratio on hydrogen embrittlement of steel;analyzes the relationship between the material properties and the hydrogen embrittlement behavior of pipeline steel,such as strength,microstructure organization,hydrogen traps;summarizes the methods to prevent and inhibit the hydrogen embrittlement behavior of pipeline steel.For the high-pressure hydrogen-blended natural gas pipeline,the operating parameters such as temperature,pressure,and hydrogen-blending ratio have a great impact on the hydrogen embrittlement.At present,there are few studies focusing on the effect of temperature on the hydrogen embrittlement of pipeline steel.With the increase in hydrogen partial pressure,the hydrogen embrittlement susceptibility of pipeline steel increases.Affected by the service life and materials of the pipeline,the ranges of the safe hydrogen blending ratio obtained by different researches are quite different.It is necessary to determine the safe hydrogen blending ratio suitable for the hydrogen-blended natural gas pipelines in China,and formulate relevant standards and specifications.Steel properties are also an important factor affecting the hydrogen embrittlement behavior.Most studies have shown that hydrogen embrittlement susceptibi
