Phased Array Corrosion Mapping

Complete turnkey PAUT solution from instruments to scanners and probes.

Ultrasonic corrosion mapping is a non-intrusive inspection technique that maps material thickness using ultrasonics. Variations in material thickness due to corrosion can be identified and graphically portrayed as an easy to interpret picture.

Eddyfi Technologies offers a complete solution with advanced phased array instruments, a range of automated and manual scanners, and a full range of probes and wedges.


Phased Array Corrosion Mapping

Recognition from various inspection bodies and asset integrity engineers has resulted in phased array ultrasonic testing (PAUT) becoming the preferred technique for corrosion mapping.

PAUT is widely used for the in-service detection and characterization of corrosion in pipes, tanks, vessels, and other critical assets. Due to a larger footprint, PAUT probes can cover a larger surface at higher speeds leading to a significant time reduction and enhanced resolution.

The automated, robust, field-proven RMA PA robotic scanner has been successfully deployed on various assets such as storage tanks, pressure vessels, pipelines, and other critical infrastructure. Ideal for extensive area inspections, difficult-to-reach assets or surfaces at an elevated temperature.

  • Remote access up to 50m (160ft).
  • Detachable R-Scan Array .
  • Range of 4 scanning heads to suit various applications.


A modular scanner with interchangeable bar lengths to suit inspection requirements. LYNCS is a versatile scanner with onboard scan controls is ideal for corrosion mapping of pipes from 100mm (4in) diameter up to flat plate. Due to its lightweight and ease of use, the scanner is perfect for rope access inspections.

  • Easily switch from corrosion mapping to weld inspection.
  • Low profile for tightly spaced pipe racks (110mm/4.3in).
  • Magnetic wheel with brakes to stop slippage.

R-Scan Array

The handheld R-Scan Array scanner allows semi-automated corrosion mapping with onboard data collection capabilities. The scanner is the perfect solution for the inspection of complex geometry components including curved surfaces, flat plate, pipelines, and restricted access areas.

  • Onboard control buttons to pause scan and stitch data sets.
  • One-handed control options and scanning handle.
  • The perfect complement to LYNCS or maximized coverage.

Probes and Accessories

Water box

The phased array configuration utilizes the Silverwing water box to create a water-column concept that eliminates the need for a wedge, thus providing the benefits of improved signal consistency, accuracy, and limited dead zone. This concept offers enhanced surface conformity and improved coupling.

  • Dual air release to remove unwanted signal disturbance.
  • Utilized in all Eddyfi Technologies corrosion mapping scanners.
  • Quick-release probe mechanism.
