Corrosion Mapping using Phased Array Ultrasonic Testing (PAUT) is a non-destructive method that scans the material thickness with ultrasonic waves. Unlike traditional point-by-point measurements, this technique provides a comprehensive visual representation of thickness distribution in the tested asset, which is essential for detecting corrosion losses.
The system records test results as a graphical thickness variation map, creating an intuitive and easily interpretable image. PAUT corrosion mapping significantly increases the speed of inspections and simplifies interpretation compared to conventional ultrasonic thickness measurements.
The PAUT method uses ultrasonic probes that can be controlled individually. This enables beam steering and focusing without mechanical probe movement. By integrating these probes with a range of automatic and manual scanners, we can efficiently and quickly inspect large-scale assets, such as pipelines on drilling platforms.
PAUT corrosion mapping is used for:
High-resolution measurements ensure the detection of even minor wall thinning, while the graphic representation of results in the form of a thickness map facilitates data interpretation.
