Guided Wave Inspection (GUI/LRUT) is a low-frequency ultrasonic wave technique developed for surveying pipe at an accelerated rate to identify potential internal and external corrosion.
- Long runs of piping in pipe/sleeper racks
- Soil-to-air interfaces
- Underground piping/cased piping/earth dike crossings
- Point contact corrosion
- Retro PMI projects (detecting welds under insulation)
- Limited-access piping (overhead lines)
- CUI Inspection
