In this paper, a new sensor for ultrasonic guided waves (UGW) acquisition is described. It is capable of localized step-by-step signal acquisition making possible defect identification and classification. In addition, the effectiveness of a method for defect classification is investigated. It is based on the evaluation of the angular profiles corresponding to each detected echo. Finally, the method was tested on experimental results.

In this paper the effectiveness of a procedure that allows the flaws characterization of pipes inspected by a long range guided waves is investigated. The method performs the extraction of correlation coefficients between the x, y, z components of the displacement of simulated guided waves reflected by defects on pipes. These features feed a neural network classifier which evaluates the dimensions of well defined geometry defects on the pipe under test. The results show lower error rates in the evaluation of both angular and axial extent of a defect.

Guided Waves (GW) have become widely used for the inspection of unpiggable and inaccessible pipelines because of the presence of coating, because of their position or because they are buried.Among the possible anomalies, corrosion is the main integrity issue affecting pipelines. The effect that corrosion has on guided wave propagation is attenuation and increased coherent noise when it is generalized or reflection when corrosion is localized.In this paper, the possibility to characterize corrosion areas affecting pipelines through long range guided wave inspection or monitoring is investigated. With this purpose field testing was performed and the results were used for the validation of numerical methods able to simulate the phenomenon.Copyright
