Abstract

Acoustic emission (AE) testing has gradually been applied to the online inspection and safety evaluation of the vertical storage tank bottom, but the evaluation is mainly qualitative, and it is difficult to evaluate the nature of the sound source (corrosion or leakage), so its application and effect are limited. A preliminary severity evaluation of corrosion defects was made, and the nature of acoustic sources was screened in this paper with confirmed AE testing cases of tank bottoms as reference samples, and the concept of similar evaluation method based on event rate and graphical features was put forward. With more experience and further research in this field and in the future, a simple and effective method for corrosion degree evaluation and defect property identification will be developed.
