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 pipelines are the main artery for the transportation of offshore oil and gas. The safe operation of submarine pipelines is directly related to the normal operation of oil and gas trades in the world and the development of domestic industries. This paper mainly studies the distribution of submarine pipelines at home and abroad, analyzes the corrosion environment and reasons of submarine pipelines, analyzes the corrosion types of submarine pipelines, adopts anticorrosive measures against these corrosion, and through the new technology Corrosion of submarine pipelines to detect the prospects for the future development of submarine pipeline anti-corrosion technology.
