Corrosion Mapping Services
Improve inspection confidence without compromising productivity: A successful corrosion mapping inspection is the result of the combination of a high probability of detection on corrosion damages like pitting, with the confidence that the full area of interest has been totally covered. In recent years, the situation has changed with the availability of off-the-shelf phased array equipment. These solutions offer an improvement of the ratio lateral resolution versus surface scanned speed as well as the availability of two axis scanners.
Regarding thickness gaging, dual element probes with a roof angle have always been preferred when looking for corrosion. The same is true for phased array inspection. The lack of interface echo will improve near surface resolution and the beam convolution will improve sensitivity and signal to noise. The broader availability of two axis scanner versus one axis has helped the gain confidence in the surface coverage. However the related restrictions of those two axis scanners in term of accessibility as well as their cumbersome deployment and lack of agility are opening opportunities for improvements.
- Agility: Works on plate, pipe and complex geometries as elbow or domes without complex and cumbersome mechanics
- Confidence: Provide real time two dimension map confirming mapping status
- Productivity: Onboard statistics, direct export to external software
- Simple and Powerful: Facilitate analysis and explanation with the use of the 3D rendering on CAD file
