Corrosion mapping scanning solution

BUILDING on the success of the Corrosion WheelProbe, a new semi-automated solution for corrosion mapping applications has been developed by Sonatest Ltd. The Veo & Corrosion WheelProbe (CWP) scanning system is a new enhancement in response to clients’ requests, providing an easier way of providing 100% coverage. The system 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 companies in the pipeline and oil and gas sectors. 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" to 42". The conformable tyre allows 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 do not normally 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. The distinct advantage of the CWP Scanning System is in the relative simplicity and

complete autonomy from the need for additional power sources on the inspection site. Ease of portability along with the speed of set-up and deployment is also a key advantage for the user in the field. Sonatest Ltd – UK Fax: +44 1908 321323
