Long Range Ultrasonic Testing (LRUT)

Long Range Ultrasonic Testing (LRUT) is a powerful non-destructive testing (NDT) method used to rapidly screen pipelines for corrosion under insulation (CUI), wall loss, and other hidden defects—especially in areas that are difficult to access, such as buried, insulated, or elevated piping. Using guided ultrasonic waves, LRUT enables inspection over long distances from a single location, significantly reducing the need for scaffolding or excavation. This not only saves time and cost but also improves safety during inspection. LRUT is suitable for all pipe sizes and materials, and it's ideal for prioritizing areas that need detailed follow-up with conventional NDT techniques.
