摘　　要：在役埋地长输管道经长时间运行之后会受到不确定因素影响而出现腐蚀问题。当腐蚀问题表现过于严重时,可能会引发埋地长输管道渗漏、破损等一系列质量缺陷问题。再加上埋地长输管道长时间处于地下工作环境,容易受到环境因素干扰而导致管道外防腐层出现破损问题。不难看出,在役埋地长输管道运行隐患因素相对较多,亟待解决。针对于此,本文主要结合在役埋地长输管道防腐现状,对管道外防腐层检测以及修复技术内容进行总结归纳。The buried long-distance pipeline in service will be affected by uncertain factors and have corrosion problems after long-term operation.When the corrosion problem is too serious,a series of quality defects such as leakage and damage of buried long-distance pipeline may be caused.In addition,the buried long-distance pipeline is in the underground working environment for a long time,which is easy to be disturbed by environmental factors,resulting in the damage of the external anti-corrosion coating of the pipeline.It is not difficult to see that there are relatively many hidden dangers in the operation of buried long-distance pipelines in service,which need to be solved urgently.In view of this,this paper summarizes the detection and repair technology of the external anti-corrosion coating of the pipeline based on the current anti-corrosion situation of the buried long-distance pipeline in service.
