Guided wave UT — screen tens of metres from a single ring.
Long-range guided-wave UT (GWT) screens long lengths of pipework, including buried, insulated and inaccessible sections, from a single transducer ring. We mobilise Teletest and Wavemaker kits across Oman to find corrosion under insulation, road and wall crossings, and buried pipework anomalies before they fail.
