海底管道的腐蚀及防治措施

Submarine Pipeline Corrosion and Prevention Measures

海底管道是海洋油气运输的大动脉,海底管道运行安全与否直接关系到世界油气交易正常运转和国内工业发展。海管安全隐患主要是由腐蚀造成,本文通过调研文献研究了国内外海底管道的分布现状,分列海底管道腐蚀环境和原因,分析了海底管道腐蚀类型,针对这些腐蚀采取防腐措施,通过新技术对海底管道腐蚀状况进行检测,对未来海底管道防腐技术的发展进行展望。

Submarine pipeline is the artery of marine oil and gas transportation, submarine pipeline running safety or not is directly related to the world oil and gas trading function and domestic industrial development. Subsea pipeline potential safety hazard is mainly caused by corrosion. In this paper, on the basis of literature researches, the distribution status of submarine pipeline at home and abroad was studied. Reasons and environment of the corrosion were lined, and types of corrosion were analyzed. Measures against the corrosion were put forward. The submarine pipeline corrosion condition was tested by new technology, and the future development trend of anti-corrosion technology for submarine pipelines was pointed out.
