The repaired pipeline system cannot be evaluated to water-leak phenomena under refillingprocess. Non-destructive evaluation of water-tightness in pipeline system is currently in urgent demand. In this study,acoustic emission (AE) method is applied to the evaluation of water-tightness in service and model pipeline systems. Theresults show that water-tightness in the pipeline system could be quantitatively evaluated by using AE parameters, such asAE generation behavior, AE energy and RMS voltage. Thus, it becomes clear that when a pipeline is being filled with waterafter the repair, the situation of water-tightness in the pipeline can be clearly identified through AE monitoring.",
