Phased array technique for inspection and measurement of contact point corrosion
Use the equipment you already have
PA-CAT uses industry standard phased array instruments, transducers, wedges, and scanners to accurately detect and measure contact point corrosion on piping and vessels. It is compatible with major OEM equipment including:
Sonatest Veo+ and Veo3
Olympus Omniscan MX2 32:128PR and X3
M2M Gekko
Zetec Topaz32 and Topaz64
Standard 32-element transducers at 2.25MHz or 5MHz are recommended, in combination with wedges contoured for the inspection surface and scan orientation.
Scanner solutions from Jireh Industries include the specially designed PA-CAT Stix scanner, as well as the possibility to use existing scanners such as the Rotix and Microbe.
Get quantitative results
PA-CAT generates a “river bottom” plot along the scan length. The patented algorithm is based on modeling the results of phased array sound transfer across dozens of real corrosion profiles. The dataset is constantly being expanded, with new pipe sizes and corrosion morphology compatiblities being added regularly.

Applicable pipe and scanning range
PA-CAT has been tested on pipe from 2” and up, and thicknesses from 0.153” (3.9mm) to 0.625” (15.9mm). Scanning can be performed in either the axial and circumferential directions. Typical probe spacing is based on pipe diameter and thickness, but ranges from 25x to 40x the wall thickness.
