Guided waves

The guided waves test is an advanced corrosion inspection method that uses low frequency guided ultrasound waves that travel along a duct, providing 100% coverage of its length. Effected areas are precisely located in terms of distance from the transducer ring and highlighted for further local examination through visual inspection or other conventional NDT methods. This non-destructive detection technique can be used without the need of extensive scaffolding and minimises the requirement of having to remove piping insulation.
