天然气管线钢CO_2腐蚀研究进展

Research Progress of CO_2 Corrosion of Internal Gas Pipeline Steel

天然气管线面临日益严重的CO_2腐蚀问题。针对管线内特定的腐蚀环境,总结了当前CO_2腐蚀在反应机理、影响因素以及腐蚀控制方面的研究进展,最后展望CO_2腐蚀研究今后的发展方向。

Gas pipelines are facing increasingly serious CO2 corrosion problem. This paper introduced the specific corrosive environment within the gas pipeline, then summarized up the CO2 corrosion research progress in reaction mechanism, influencing factors and current corrosion control measures. At last, the research direction of CO2 corrosion of gas pipeline was proposed.
