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、CH4、O2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.
Research Progress on Hydrogen Embrittlement Protection against Hydrogen-doped Natural Gas Pipelines
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 en-vironment of pipelines.Inhibiting gases such as CO,CH4 and O2 can be inhibited by competitive adsorption alone or in co-ordination with hydrogen embrittlement.Common alloy coatings and two-dimensional novel materials with high hydrogen re-sistance(graphene,BN,MXene and TMDs).The pipeline steel is modified by heat treatment and addition of alloying ele-ments,including heat treatment to adjust the structure and grain boundaries,adding alloying elements to increase hydrogen resistance precipitates,etc.
