Guided Wave (GW)
Guided wave ultrasonic testing detects corrosion damage and other defects over long 33 ft – 165 ft distances in piping. A special tool (transducer ring) is clamped around the pipe and transmits guided waves in both directions along the pipe. Reflected signals from defects and pipe features such as welds are received by the transducer ring and sent to the main unit.
