Building on the proven success of Corrosion WheelProbe a new semi-automated solution for corrosion mapping applications has been developed by Sonatest Ltd; the Veo & Corrosion WheelProbe (CWP) Scanning system. The CWP Scanner is a new enhancement in response to clients’ requests, providing an easier, semi-automated way of providing 100% coverage.

The system as a whole consists of the veo 16:64, a phased array flaw detector, a 64 element Corrosion WheelProbe and a CWP scanner. The Corrosion Wheel Probe is a tried and tested solution for corrosion mapping by many leading companies in the Pipeline and Oil & Gas sectors, hence the development of this system.

The scan width of a Corrosion WheelProbe (CWP) is close to 50mm in one pass and it can be used on pipe diameters from 4 - 42 inches. Importantly the conformable tyre allows excellent coupling to rough surfaces, and the design allows for consistent reliable inspection in both depth and amplitude. This amplitude mode enhances the possibility of finding small pit type defects, which normally do not give a good ultrasonic response, however results show excellent indications of internal condition.

The CWP is fitted to an adjustable connector, equipped with a second encoder, and allows for multiple adjacent scans with a good overlap for complete coverage.
