The Acoustic Emission Testing of the Pressure Shell of Large Structure in Hydraulic Pressure Experiment

Aiming at the hydraulic pressure experiment of the primary entering air pipeline of large structure, and referring to the interrelated request of standard GB/T 18182—2000, the structure integrity evaluation and alive level monitor of a flaw were carried on in this paper. It concluded that the acoustic emission could evaluate and monitor the pressure shell of large structure in hydraulic pressure experiment.
