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.
