Abstract :

This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The result of AE test in the studied oil tank verifies the presence of corrosion in some areas of the tank floor. After AE test, the tank emptied and inspected using ultrasonic thickness meter. The result of thickness measurement reconciles in an acceptable manner with AE test.
