The characteristics of naphthenic acid corrosion of pipeline are introduced briefly and the corrosion mechanism of naphthenic acid corrosion is analyzed. The effect of naphthenic acid corrosion caused by the flow rate and erosion-corrosion is also expounded. The latest results of the research on the effect of the resistance performances of high-temperature naphthenie acid corrosion caused by chemical compositions of materials are reported. The method to prevent the high-temperature naphthenie acid corrosion of pipeline by controlling the flow rate and selecting the appropriate materials is brought forward. Moreover, the improvement of in the materials of atmospheric and vacuum equipment pipeline on oil processing is expounded and the prospect for a further study of naphthenie acid corrosion is also mentioned, so that it can be used as a reference in the field of acidic crude oil corrosion and safety of the equipment pipeline.
