Method Research on Corrosion Risk Analysis of Underground Oil Pipeline System

Risk analysis is an efficiency method to reduce accident loss, save repair cost, and make ensure the safety operation of pipeline. At the same time, corrosion is the main cause of most risk problems. So, in this paper, based on the corrosion mechanism of pipeline and the theory of risk analysis, an effective method for evaluating corrosion risk of underground oil pipeline system is put forward. All of these are validated by an instance of real oil pipeline at the end of this paper.
