摘　　要：本文阐述了合成氨厂氨洗塔系统管道腐蚀的严重性，指出了引起腐蚀的综合性原因，分析了ＮＨ＿３－ＣＯ＿２－Ｈ＿２Ｏ，Ｈ＿２Ｓ－ＣＯ＿２－Ｈ＿２Ｏ，Ｆｅ＿２Ｏ＿３－Ｏ＿２－Ｈ＿２Ｏ等体系给管道带来腐蚀的理论依据。通过多年的生产实践和检验测定明确了造成管道腐蚀的主要原因，并提出了防止管道腐蚀的六条措施。This paper presents the gravity of pipe corrosion on ammonia-water absorption column system in ammo- nia synthesis plant,pointing out the comprehensive reasons causing pipe corrosion and tracking down the theoreti-cal proof causing pipe corrosion by such systems as NH_3-CO_2-H_2O,H_2S-CO_2-H_2O and Fe_2-O_2-H_2O.The main reasons causing pipe corrosion are ascertained through years of testing and measuring,therefore propos-ing six measures to prevent pipes from being corroded.
