In this paper, the investigation of the current situation of the interference investigation and protection technology of the gas pipeline stray current in China is carried out. According to the current situation of the gas pipe in the new district of the city affected by the interference of the stray current, the principle and category of the stray current are analyzed. According to the main influence modes, Of drainage methods to explore and found that in the absence of a universal protective measures, drainage protection is the most important and most effective method.
