摘　　要：埋地管道外防腐层作为隔断管道与土壤直接接触的屏障,具有使管道免受电化学腐蚀和细菌腐蚀的作用。防腐层一旦破损,管体表面就将会发生腐蚀,严重威胁管道安全。利用DCVG检测技术,开展庆哈输油管道全线的防腐层检测,对测试结果进行分析评价,提出合理的建议,减少管道的腐蚀,对管道的安全运行具有重要意义。The buried pipeline external corrosion protection layer as a barrier between the pipeline and the soil direct contact with the pipeline to avoid electrochemical corrosion and the role of bacteria corrosion .Once the corrosion protection layer is broken, the surface of the pipe will be corroded , which is a serious threat to the safety of the pipeline .The DCVG detection technology , the development of Qing ha oil pipeline across the board of anticorrosive layer detection , analysis and evaluation of test results , put forward reasonable suggestions , to determine the pipeline every are not within the scope of protection of the corrosion , safe operation of the pipeline has important significance .
