摘　　要：管道腐蚀防护管理工作贯穿管道全寿命周期,这直接关系到埋地管道的使用期限和安全运行。如何持续提高管道腐蚀防护水平、消除腐蚀危害是成品油管道管理的永恒主题。通过定期检测成品油管道的运行状况,开展外检测全覆盖,能够及时掌握成品油管道的安全状态。本文依据武信成品油管道外检测(ECDA)结果,对管道整体情况进行分析与杂散电流整治,通过测试进一步验证整治效果。The management of pipeline corrosion protection runs through the whole life cycle of pipeline,which is directly related to the service life and safe operation of buried pipeline.How to continuously improve the level of pipeline corrosion protection and eliminate corrosion hazards is the eternal theme of product pipeline management.Through the regular inspection of the operation status of the product pipeline and the full coverage of the external inspection,the safety state of the product pipeline can be grasped in time.In this paper,according to the results of external inspection(ECDA)of Wuxin product pipeline,the overall situation of the pipeline is analyzed and stray current regulation is carried out,and the regulation effect is further verified by testing.
