Defect Detection using Power Spectrum of Torsional Waves in Guided-Wave Inspection of Pipelines

Ultrasonic Guided-wave (UGW) testing of pipelines allows long-range assessment of pipe integrity from a single point of inspection. This technology uses a number of arrays of transducers separated by a distance from each other to generate a single axisymmetric (torsional) wave mode. The location of...
