Pipeline electric heat tracing system has been widely used in the field of national defence industry, but there are also various problems in the actual use process. In order to solve the problem of safety evaluation of pipeline electric heat tracing system, on the basis of analyzing and summarizing the common faults of pipeline electric heat tracing system, 17 influencing factors were selected to construct the safety evaluation index system of pipeline electric heat tracing system in terms of system design, installation and construction, electrical connection and operation. The weight value of each scheme layer was calculated by improved analytic hierarchy process, and a grey clustering evaluation of pipeline electric heat tracing system safety was proposed. The effectiveness of the model was verified by an example of electric heat tracing pipeline. The results indicate that the model can not only objectively and accurately evaluate the safety of the pipeline electric heat tracing system, but also quickly find the weak links of the system safety, and has strong practical application value.
