| 中文摘要: |
| X80管线钢因具有高强度、高韧性、抗脆断等性能,已成为现代油气运输中应用最为广泛的钢材之一。X80管线钢在埋地土壤环境中不可避免地受到应力和SRB(Sulfate-reducing bacteria)的共同作用,近年来有关X80管线钢在含SRB的土壤环境中的应力腐蚀开裂已成为一个研究重点。综述了应力腐蚀开裂和SRB腐蚀的影响因素,总结了关于应力和SRB协同作用对X80管线钢腐蚀行为影响的研究现状,分析了现行研究的缺陷和不足,并针对这些问题对今后的研究进行了展望。 |
| 英文摘要: |
| X80 pipeline steel is widely used in oil and natural gas pipeline transportation field due to its high strength, high toughness and excellent corrosion-resistance. The buried X80 pipeline steel is unavoidably affected by the synergistic effect of stress and SRB (sulfate-reducing bacteria), so the stress corrosion cracking behavior of X80 pipeline steel in the soil environment containing SRB has been studied as an academic research focus. In this paper, the influence factors on stress corrosion cracking and SRB corrosion are reviewed. The synergistic effect of stress and SRB on the corrosion behavior of X80 pipeline steel is summarized. The existed problems are analyzed and the further direction of research is also prospected. |
