One of the dependencies of most ultrasonic pipeline inspection tools is a liquid medium.
This limitation has made ultrasonic inspection of gas pipelines a challenge in the past. We developed a solution to this limitation based on acoustic resonance technology (ART).
ART works by emitting a wideband acoustic waveform toward the pipe wall. This waveform excites numerous standing compressional waves between both surfaces of the pipe wall. The ART tool then measures the acoustic energy reflected by the pipe wall’s standing compressional waves. The returning energy signal includes a signature resonance pattern, which directly indicates pipe wall thickness.
