In order to restrain natural gas pipeline corrosion effectively, reduce economic cost and security incident, this paper discusses the corrosion mechanism and influencing factors of hydrogen sulfide and carbon dioxide, and the technological process of coating and catholic protection as well, introducing how to monitor the corrosion with GPS, GIS, and SCADA system. By analyzing the outer coating performance, forced current and sacrificial anode catholic protection method and stray current treatment programs, and based on the practice, this paper proposes the gas pipeline anticorrosion plan.
