　　为了有效抑制天然气管道腐蚀，降低经济成本和减少安全事故。论述了硫化氢(H2S)、二氧化碳(CO2)腐蚀机理及其影响因素，涂层和阴极保护工艺流程，应用全球定位系统(GPS)、资源与环境信息系统(GIS)、数据采集与监视控制系统(SCADA)系统对腐蚀进行监控。对比内、外涂层性能，强制电流和牺牲阳极阴极保护方法以及杂散电流处理方案，依据成都燃气实际，提出燃气管道防腐方案。

In order to inhibit pipeline corrosion of natural gas effectively reduce economic cost and security incident. Discussed H2S,CO2 corrosion mechanism and influencing factors ,coating and cathodic-protection process, the application of GPS, GIS , SCADA system to monitor the corrosion. In contrast, the outer coating perform-ance, forced current and sacrificial anode cathodic-protection method and stray current treatment programs based-on the Chengdu Gas actual, proposed gas pipeline corrosion program.
