人工煤气管道内壁腐蚀分析及防腐措施
Corrosion Analysis and Anticorrosion Measures of Internal Wall of Manufactured Gas Pipeline
【摘要】 分析了煤气管道内壁局部腐蚀的机理和原因,煤气管道的内应力和煤气中的杂质是造成煤气管道腐蚀的主要原因,其中硫化氢是造成电化学腐蚀的重要杂质。针对产生腐蚀的原因给出了防腐措施。
【Abstract】 The mechanism and reasons of local corrosion of internal wall of coal gas pipeline are analyzed.The internal stress of coal gas pipeline and impurities in coal gas are main reasons causing coal gas pipeline corrosion,and hydrogen sulfide is an important impurity causing electrochemical corrosion.Some anticorrosion measures are proposed in the view of the corrosion reasons.
