Long Range Ultrasonic Testing (LRUT) is an advanced non-destructive examination technique that was developed for testing large volumes of material from a single test point.
LRUT is a method for the rapid screening of pipework for corrosion and erosion. The technique differs from conventional ultrasonic testing in that it uses plate or Lamb waves instead of bulk waves and the frequency is in the order of kHz rather than MHz. Plate waves penetrate the whole thickness of the plate and the ratio of plate thickness to the ultrasonic wavelength is such that the waves on the two surfaces interact.
