In order to control the corrosion problems of a sub-high-pressure natural gas pipeline suffered dynamic DC stray current interference a series of field testing were conducted including the pipe-to-soil potential soil resistivity the sacrifice anode performance and stray current parameters etc. The test results show that the pipeline is mainly influenced by the the city subway dynamic DC stray current interference flowing in or out the anodes which are used for cathodic protection. Experiments about pre-feasibility studies using forced current drainage method or polarity drainage method were carried out on a 4 km pipeline segment. According to the results of the experimental test section the polarity drainage method was impled on the whole pipeline which improved the pipeline cathodic protection status. Also some pipeline segment which is originally under protection achieves the requirements of the normal protective criteria.
