Long Range Ultrasonic testing (LRUT) System (Guided Waves)

Tens of meters of pipeline can be assessed for internal, external corrosion or combination thereof in either direction from a single location achieving 100% coverage of the pipe wall. Up to ten (10) locations are achievable in one (1) day, equating to many hundreds of meters of evaluation per day. This technique produces a computer generated 'A' scan type trace of the inspection length. The technique locates areas of cross sectional material loss giving this in terms of a percentage loss of wall thickness. It also gives an accurate distance of the anomaly from a given datum.
