This paper introduced the urban buried gas pipeline corrosion theory and anode and cathode sacrificial protection used in the urban gas pipeline antisepsis. The improvements on the structure improvement of test pile, the adjustment of anode and the layout of test piles are mainly discussed in the paper. It＇s hoped that cathode protection can be better used in buried pipeline of the cities and towns. It＇s found that cathode protection has certain value in gas pipeline corrosion protection engineering.
