摘　　要：防腐层性能的好坏直接影响到管道的使用寿命。而由于施工质量、自然老化等原因导致埋地管道防腐层破损的现象时有发生。因此,适时开展防腐层的检测与修复十分必要。在分析国内埋地管道防腐技术现状的基础上,介绍了目前常用的几种管道外防腐层检测技术和防腐层修复工艺,最后根据济淄线管道防腐层检测与修复的实践,提出了几点建议。The performance of external coating directly affects the service life of pipeline. And because of constructional qual- ity, natural ageing etc, the damage of external coating has frequently appeared. Therefore, it is necessary to detect and rehabilitate external coating in time. Based on analyzing the domestic status of coating technology, this paper describes several detection and rehabilitation methods commonly used. Finally, according to the project practice on Jinan-Zibo line, recommendations are made to guide the detection and rehabilitation of external coating.
