The Long Range Detection of Corrosion in Pipes Using Lamb Waves

Abstract

Ultrasonic nondestructive testing techniques are available for the detection of general wall loss associated with pitting and corrosion, but unfortunately they tend to be very slow, single position measurements, making the inspection of the kilometres of pipeline typically found in iAlleyne, D., & Cawley, P.

The aim of the experimental investigation was to preferentially excite the axially symmetric L(0,2) mode and to measure the amplitude of the reflections from the feature under test.
