Advanced ultrasonic testing for CUPS at height with QSR1 system

Page last modified
November 25 2022

Applus+ RVIS delivers in-service inspection of CUPS at height without the need for scaffolding. The latest ultrasonic technology and the in-house developed remotely operated lift allows semi-automated inspection of CUPS at height. Our system uses QSR (quantitative short range) device to provide quantitative information on the remaining ligament. Both internal and external degradation can be detected and, in principle, sized, such as touchpoint corrosion under pipe supports (CUPS), erosion, corrosion and mechanical damage to the pipe. The device automatically measures the size of corrosion to the depths of up to half of the pipe wall thickness. Results are automatically analysed and reports can be readily generated. With this inspection service, Applus+ RVIS offers to combine remote visual screening of CUPS at height and use ultrasonic testing only where deemed necessary to measure wall thickness.


Deployment at height without the need for scaffolding
Two fundamental and complementary inspection tools (visual and UT) for rapid screening and identification of critical CUPS
No couplant necessary
Less sensitive to surface condition and human error
No expensive preparatory work required
Automated scanning and data analysis
Limitations of pipe sizes and thickness profiles


Inspection Inspects pipes on simple supports for touch point corrosion.
Measurement Measures quantitatively up to 50% wall loss and qualitatively at greater than 50% wall loss.
