Short Wave Ultrasound Inspection (SWUT)

Short Wave Ultrasonic testing – SWUT is a form of screening non-destructive method to detect corrosion/erosion/pitting on the pipe wall or plates concealed under support structures or structural shell. The customized SWUT probe is placed away from the area of interest (generally concealed surface) to scan up to 1m of material length without losing adequate sensitivity. Approximately 50mm equivalent diameter area (free from coating) is essential to contact the specialized probe on the material. Testing can be performed while the plant or assets are in-service. Annular rings under the Tanks shells are best inspected using SWUT.
