Rapid Pipeline Inspections: Where Does GWUT Stand?
One of the longstanding problems facing the global oil & gas industry has been how to efficiently detect corrosion under insulation (CUI) in pipework. Over the years, a plethora of non-destructive testing (NDT) solutions have been developed to solve this problem with varying degrees of success. One technology that stands out however, is Guided Wave Ultrasonic Testing (GWUT).
Guided Wave Ultrasonic Testing works by generating mechanical stress waves that propagate along an elongated structure while guided by its boundaries. The generated waves can travel a long distance with little loss in energy, thus making them efficient.
