Long Range ultrasonic test

LRUT is primarily a screening tool. The aim of the inspection is to test long lengths of pipe rapidly from a single test point with 100% coverage of the pipe wall and to identify areas of corrosion.

How ?

Torsional or longitudinal guided waves are induced into the pipe body and propagated along the pipe segment being inspected. When these guided waves identify an anomaly or pipe feature their mode convert into laminar waves and reflect to the tool’s original location. Using a laptop these signals are digitally captured and processed. The time-of-flight for each signature is calculated to determine the distance from the tool and the significance of the anomaly. The octants determine the position around the pipe

Applications includes but not limited to:

  • Sleeved Road Crossings
  • Corrosion Under
  • Insulation (CUI)
  • Buried Pipe
  • Wall Penetrations
  • Pipe Racks
  • Corrosion under supports
  • Offshore Risers and Caissons
