The semi-quantitative evaluation method was used to evaluate the failure possibility of polyethylene gas pipeline.Combined with the charac-teristics of polyethylene gas pipeline,an evaluation model for failure possibility of polyethylene gas pipeline was established by considering five factors:third-party damage,inherent hazards of pipeline,corrosion hazards of pipeline,inadequate management hazards and serv-ice environment.The weight calculation method of the failure possibility evaluation model was determined by the analytic hierarchy process,the weights of each fac-tor were obtained,and the consistency test was carried out.The failure possibility of three polyethylene gas pipeline sections in a certain area was evaluated,and the results obtained were highly consistent with the ac-tual situation.
