摘　　要：结合目前掺氢天然气研究现状,从管线钢氢脆的角度,根据管线服役环境提出几种氢脆防止措施:可以单独或者协同竞争吸附来抑制氢脆的CO、CH 4、O 2等抑制性气体;常见的合金涂层以及具有高阻氢性能的二维新型材料(石墨烯、BN、MXene和TMDs);通过热处理和添加合金元素对管线钢改性,包括热处理调整组织与晶界、添加合金元素增加阻氢析出物等。In order to promote the strategic goal of low-carbon development,hydrogen transportation through natural gas pipelines,as one of the important means to achieve large-scale,long-distance and low-cost hydrogen transportation,has been vigorously developed in recent years.However,the addition of hydrogen to the safety of pipeline transportation can not be ignored.Based on the current research status of hydrogen-doped natural gas,this paper proposes several measures to prevent hydrogen embrittlement from the perspective of hydrogen embrittlement of pipeline steel according to the service environment of pipelines.Inhibiting gases such as CO,CH4 and O2 can be inhibited by competitive adsorption alone or in coordination with hydrogen embrittlement.Common alloy coatings and two-dimensional novel materials with high hydrogen resistance(graphene,BN,MXene and TMDs).The pipeline steel is modified by heat treatment and addition of alloying elements,including heat treatment to adjust the structure and grain boundaries,adding alloying elements to increase hydrogen resistance precipitates,etc.
