Steam pipeline network is an important way to achieve maximum energy utilization in the petrochemical and power industries.Accurate risk assessment is of great significance for its safe operation.However,the current risk assessment method applied to petrochemical industry has limited applicability to steam pipeline network.Based on analytic hierarchy process(AHP)and fuzzy comprehensive evaluation method,this article proposes a risk assessment method for steam pipeline network by considering the impact of potential risk types on the failure likelihood,which is further applied in a certain enterprise.The results indicate that the evaluation results are closer to the actual situation,and thus improving the accuracy of risk assessment for the steam pipeline network.
