煤制合成天然气管道材料适用性评价方法

Applicability Evaluation Method of Coal Synthetic Natural Gas Pipeline Material

通过对现有输氢管道及储氢容器的标准进行梳理,结合相关文献资料,对煤制气管道在含氢环境中的适用性评价方法进行总结。从管道的强度,塑性,断裂韧性,疲劳等几个方面提出氢脆敏感性的评价方法和判断依据,为含氢煤制合成天然气管道材料的服役适用性评价和安全运行提供了技术支持。

Through combing the existing standards of hydrogen pipelines and hydrogen storage vessels,combined with relevant literature,the applicability evaluation methods of coal gas pipelines in hydrogen-containing environment are summarized.From the aspects of strength,plasticity,fracture toughness and fatigue of pipelines,the evaluation methods and judgment basis of hydrogen embrittlement sensitivity are proposed,which provides technical support for the evaluation of serviceability and safe operation of hydrogen-containing coal-made synthetic natural gas pipeline materials.
