Long Range Ultrasonic Testing (LRUT) is an advanced nondestructive examination technique that was developed for testing large volumes of material from a single test point. What differentiates this from more traditional methods of ultrasonic testing is that, with LRUT, a liquid couplant between transducers and the surface is not required. For this reason LRUT is one of the fastest inspection tools for carrying out pipeline surveys for corrosion and other damage mechanisms.
