Published Online: March 4, 2005
... what happens in a pipe for ultrasonic guided wave. For longitudinal guided waves in a pipe, the approximation is valid clearly only over a very short distance or inordinate closeness to a defect for wave scattering analysis; but for circumferential guided waves, the validity is unclear and therefore...

Defect Classification in Pipes by Neural Networks Using Multiple Guided Ultrasonic Wave Features Extracted After Wavelet Processing

Piervincenzo Rizzo, Ivan Bartoli, Alessandro Marzani, Francesco Lanza di Scalea
Journal: Journal of Pressure Vessel Technology
Publisher: ASME
Article Type: Research Papers
J. Pressure Vessel Technol. August 2005, 127(3): 294–303.
https://doi.org/10.1115/1.1990213
Published Online: January 27, 2005
...Piervincenzo Rizzo; Ivan Bartoli; Alessandro Marzani; Francesco Lanza di Scalea This paper casts pipe inspection by ultrasonic guided waves in a feature extraction and automatic classification framework. The specific defect under investigation is a small notch cut in an ASTM-A53-F steel pipe...
