Data-Driven Urban Gas Pipeline Integrity Detection and Evaluation Technology System

At present, PE pipelines are widely used in urban gas pipeline networks. As safety is of great importance to the supply, this paper focuses on and reliability pipes during service. First all, analyzes aging factors materials failure forms mechanisms pipes. Second, performance testing methods summarized, including pressure tests, condition inspections, welded joint mechanical physical tests. In addition, life prediction for introduced analyzed. The applicability tensile experiments DSC based thermal oxygen both analyzed, corresponding also carried out. On basis above research, technical system integrity detection evaluation finally established. includes method determination retest cycles, which can provide a reference safe operation
