The Wavemaker Pipe Screening System uses low frequency guided ultrasonic waves that propagate along the pipe wall and is designed for rapid screening of long lengths of pipe to detect external or internal corrosion as well as axial and circumferential cracking. This is composed of three primary components, the transducer ring, the Wavemaker G3 instrument, and the controlling computer.  All aspects of the system, such as electronics, software, probes and clamping arrangements are designed and manufactured in-house.

The transducer rings use mechanical or pneumatic pressure to dry couple piezoelectric transducer elements to the pipe being inspected. Transducers attached to the pipe send waves tens of metres along the pipe wall and the returning echoes indicate defects and other features. Therefore long lengths of pipe are examined from one location which allows difficult to inspect areas, such as roadways, to be screened with ease. Minimal preparation before the test is required.

Access on short length of pipe on 360 degrees
Minimal cleaning (remove insulating material, thick coating and loose paint/flaking corrosion at test locations)
No couplant required
