Application of AE Technology on Detecting the Leakage Location of Storage Tank Floor

Two vertical atmospheric storage tanks with leakage were detected by AET to locate the leakage sites on the floors, and in turn to make the repair more effective. One of two storage tanks was monitored using water as the test liquid instead of working medium, and another one was monitored in service during the leakage. Two different modes of detection were satisfactory. Present work was very helpful for achieving experiences on AE inspection in field.
