Abstract: The invention relates to systems and methods for conducting an ultrasonic, nondestructive evaluation and inspection of a pipe using Lamb-type wave transducers to detect the presence of defects, flaws, discontinuities and the like. The transducers are positioned within the interior space of the pipe. Two transducers are positioned facing each other such that the ultrasonic beam emitted from each of the transducers is directed toward the other transducer and the portion of pipe to be inspected. The coverage of the transducers is verified and the results are processed using a combination of a cross correlation filter and a signal processing tool.
