The acoustic emission (AE) technique was implemented to monitor different failure stages in steel cylinders used to store Liquefied Petroleum Gas (LPG). Experiments in two containers with external and internal defects subjected to a hydrostatic test were carried out. The severity of the faults was progressively increasing through the different stages to study the microseismic activity. The experimental tests allowed checking the Kaiser and Felicity effects. Additionally, it was observed that an increase in the severity of the failure depicts an increase in the number of hits, counts and energy values detected. The evolution of the acoustic activity for the different failure stages established the container's structural integrity, proving that AE allows evaluating its entire condition.
