摘要

天然气管道混氢和纯氢管道输氢是可再生能源转型过程中具有发展前景的能源输送方式。为了保证管道的安全运行，首先要对管道钢的氢脆风险进行量化。本文综述了管道钢中的HE。当暴露在100巴以上的氢分压下时，大多数管道钢的延展性都会降低。高强度管线钢(X80和X100)在~ 50 bar的氢气条件下也能进行HE。管道钢中氢诱导的亚临界裂纹扩展在文献中尚未报道。关于管道焊缝中HE的文章很少，有的表明焊缝更容易受到HE的影响，有的表明较少。氢压力与吸收氢浓度之间的关系尚未得到评价。在结论中指出了知识上的差距。

A review of hydrogen embrittlement in gas transmission pipeline steels

Abstract Hydrogen transport by blending hydrogen into natural gas transmission pipelines and by pure-hydrogen pipelines is a prospective mode of energy transmission during the transition to renewables. The risk of hydrogen embrittlement (HE) in pipeline steels must first be quantified to ensure safe pipeline operation. This review provides an overview of HE in pipeline steels. Most pipeline steels have reduced ductility when exposed to hydrogen partial pressures of 100 bar and above. Higher-strength pipeline steels (X80 and X100) have been found to undergo HE at ∼50 bar hydrogen. Hydrogen-induced subcritical crack growth in pipeline steels has not been reported in the literature. There are few articles on HE in pipeline welds, with some indications that the weld is more susceptible to HE, and some indications that it is less. The relationship between hydrogen pressure and absorbed hydrogen concentration has not been evaluated. Gaps in knowledge are identified in the conclusions.

期刊介绍： Corrosion Reviews is an international bimonthly journal devoted to critical reviews and, to a lesser extent, outstanding original articles that are key to advancing the understanding and application of corrosion science and engineering in the service of society. Papers may be of a theoretical, experimental or practical nature, provided that they make a significant contribution to knowledge in the field.
