针对城市埋地钢质燃气管道的腐蚀,分析了化学、电化学、细菌、杂散电流等因素对管道腐蚀的影响。燃气管道腐蚀后具有安全隐患,严重影响供气安全性。为避免燃气管道腐蚀带来的严重后果,提出防治燃气管道腐蚀的措施,以延缓管道腐蚀,保证燃气供应的安全、平稳。
In view of the corrosion of the buried steel gas pipeline in the city, the influence of chemical, electrochemical, bacteria, stray current and other factors on corrosion of pipeline is analyzed. After the gas pipeline has a potential safety hazard, seriously affecting the gas supply safety. In order to avoid serious consequences of gas pipeline corrosion, measures to prevent corrosion of gas pipelines are put forward to delay pipe corrosion and ensure gas supply safety and stability.
