摘　　要：通过对被加热输油管道外壁腐蚀物的X射线衍射、SEM二次电子形貌观察、波谱及化学分析,研究了其物相组成。元素构成及微观形貌,探讨了其腐蚀机理,主要是硫引起的硫酸露点腐蚀,并据此提出了降低或避免腐蚀的措施。This paper deals with the corrosion of the outer wall of heated petroleum pipeline with the aid of x-ray diffraction,SEM,wave spectrum and chemical composition analysis. The corrosion mechanism is discussed. The results show that sulphur forming sulphur acid results in the corrosion of petroleum pipeline surface layer. Based upon it ,the approaches to diminish or avoid the corrosion are suggested.
