Acoustic Emission (AE) technique is considered as a Non-Destructive Testing (NDT) method used in monitoring and in the inspection of structural flaws. The AE signal is the generation of the rapid release of strain energy that usually occurs within the material during crack propagation or burst of gas leakage. One of the applications of this method is to monitor possible flaws that might take place specifically in pipeline installations. This could also be used to locate the leak source and effectively characterize the development of defects such as deformation, corrosion, cracks, etc. Thus,...
