This article introduces how to determine the conditions under which a defective pressure vessel can continue to use and operate in a safety way
by means of acoustic emission technique.Acoustic emission tests under hydraulic pressure can monitor the dynamic variation of vessel's defectiveness
determine the pressure under which the vessel operates in a comparatively un-noisy way.Such tests offer guidance for conventional flawless tests
shorten the test process
and play a critical role in determining the conditions under which a defective pressure vessel operates in a safety way.
