摘　　要：腐蚀对管道系统的可靠性和使用寿命起到关键作用,油气集输管线的失效形式主要表现为腐蚀失效。每年因腐蚀引发的事故不胜枚举,造成经济损失和人员伤亡的严重后果。从管道内外壁腐蚀两个方面论述了导致天然气管道腐蚀的原因,并有针对性的提出了预防腐蚀的措施。为天然气管道实际防腐提供了必要参考和理论依据。Corrosion is crucial to the reliability and service life of piping system, the main failure mode of gas and oil pipelines is corrosion failure. The number of accidents caused by corrosion is too numerous to enumerate every year, which causes serious economic losses and casualties. In this paper, reasons to cause corrosion of natural gas pipelines were analyzed from two aspects of inside and outside wall corrosion, and anticorrosion measures were put forward, which can provide necessary references and theoretical basis for actual anticorrosion work of natural gas pipelines.
