Phased Array Composite Assessment Technique
Reduce false readings with improved inspection
Phased Array Composite Assessment Technique
Phased Array Corrosion Assessment Technique (PA-CAT) is a specialised application of Phased Array Ultrasonic Testing (PAUT), designed specifically for corrosion mapping and wall thickness profiling over large or irregular surfaces.
PA-CAT uses a phased array probe in combination with a scanning device (manual or automated) to produce detailed, high-resolution images of corrosion damage.
It provides quantitative data on remaining wall thickness across a surface area, making it ideal for assessing pipework, vessels, tanks, and other critical components.
Key Benefits:
- Accurate corrosion mapping over large or complex surfaces
- High-resolution, real-time imaging of wall loss and pitting
- Quantitative thickness measurements for integrity assessment
- Can be used with encoded scanning for full data traceability
- Reduces need for spot-check UT and improves inspection coverage
- Ideal for CUI (corrosion under insulation) and coated surfaces.
PA-CAT helps operators make informed decisions about repairs and asset life extension by delivering comprehensive, reliable corrosion data in a format that’s easy to analyse and document.
