Abstract
Taking the corrosion condition of HFW X65 welded pipe, which used for oil pipeline and stacked at open storage ground after one year, as an example, the corrosion characteristics and mechanism of the line pipe were researched by using the optical microscope, scanning electron microscope and other analysis methods. The results indicated the corrosion pits on sample surface belongs to electrochemical corrosion, and are related to materials stack environment and time. The inclusions inside material and abnormal surrounding structure may become the original point of corrosion, and cause steel corrosion. Finally, some prevention measures for HFW pipe open storage ground were put forward.关键词
