Development and Application of Acoustic Emission Leak Detectors

B. M. Lapshin, A. L. Ovchinnikov, A. S. Chekalin

Basic physics are described for the Acoustic Emission (AE) method used for pipeline leakage testing. The necessary conditions for AE initiation are indicated, information of method sensitivity and spectral distribution of signals is given. Many years’ experience on making and approbation AE leakage testing devices for different pipelines is discussed. Advantages and disadvantages of the devices are analyzed.
