Research on AE Source Location
and Identification Method of Tank
Bottom Corrosion
Feng Qiu, Guang Dai, Mingjun Li, Dingrong Qu, and Yongliang Yu
Abstract As large storage tank has large diameter, the acoustic emission (AE) wave
attenuation will increase. The number of location events may be lost. The activity
of the defect cannot be understood. Reliability of safety assessment of tank bottom
corrosion will be affected. In order to solve the problem, an acoustic source identification method is presented. Based on the AE source location theory of tank bottom,
it is put forward that the sensors located on the tank bottom medium are employed
together with the sensors arranged on tank outside wall near tank bottom to identify
the acoustic source of tank bottom corrosion defects. Experiments of acoustic source
location and identification for simulative tank bottom corrosion have been conducted.
The results show that the method can help for recognizing acoustic source in arbitrary triangle and area location of tank bottom area; in addition, the sensor inside
the tank is more sensitive to the identification of corrosion acoustic source than the
external sensor. Therefore, the method can improve the reliability of results for the
identification and location of tank bottom acoustic source.
