阿赛输油管道投产几年来多次发生腐蚀穿孔事故,对管道安全运行构成很大威胁。利用传统的经验技术来定位实施管道大修,不仅对消除腐蚀隐患存有很大的盲目性,而且造成大修理费用的增长。介绍了漏磁腐蚀检测技术原理及在阿赛输油管道上应用的具体情况。内检测技术的实施不仅可准确地检测出管道的隐患,为管道安全平稳运行提供了保证,而且由于检测的精确,定位准确率高,使管道大修理费用较以往传统的定位修理大大降低,具有可观的经济效益。
Asai oil pipeline put into operation several times over the corrosion and perforation accidents, pipeline safety operation poses a great threat. The use of traditional experience and technology to locate and implement pipeline overhaul not only has a great blindness to eliminate the hidden dangers of corrosion, but also causes an increase in the cost of overhauling. The principle of MFL detection technology and its application in the ArcelorMittal pipeline are introduced. The implementation of the internal inspection technology can not only accurately detect the hidden danger of the pipeline, and ensure the safe and steady operation of the pipeline, but also greatly reduce the cost of overhauling the pipeline over the traditional positioning and repairing due to the accurate detection and high positioning accuracy. Considerable economic benefits.
