油气管道直流杂散电流腐蚀防护研究进展

摘要

以国内外油气管道直流杂散电流腐蚀的研究成果为基础,分析了直流杂散电流腐蚀的机理、特点,列举了国内外直流杂散电流腐蚀测试方法,同时总结了目前直流杂散电流腐蚀的防护技术与防护方案. 基于国内外对直流杂散电流腐蚀的研究进展,通过对比分析,提出了测试与防护的相关建议.%Based on the research results of DC stray-current corrosion of oil and gas pipeline at home and abroad, the mech-anism and characteristics of DC stray-current corrosion were analyzed. The DC stray-current corrosion test methods at home and a-broad were listed. At the same time, the current DC stray-current corrosion protection technology and protection scheme were summarized. Based on the study of DC stray-current corrosion at home and abroad, advices on testing methods and protection strategies are given by comparision.
