Phased Array Corrosion Mapping

Eddyfi Technologies’ automated corrosion mapping solutions leverage advanced Phased Array Ultrasonic Testing to deliver precise, high-resolution data with a 1mm (0.04in) resolution. These systems are engineered to optimize productivity while maintaining a high Probability of Detection (PoD), ensuring even the smallest defects are detected with unparalleled accuracy.

At the core of this system is the Aqualock waterbox technology, which provides stable water-column coupling that improves signal consistency, eliminates the need for a wedge, and enhances surface conformance. The unique flow dynamic air bubble removal design results in superior coupling for reliable inspections, even on challenging surfaces. The foam seal liner maximizes durability on rough surfaces, keeping you on track for your productivity goals. The combination of the Aqualock system and the 7.5MHz 64-element probe allows the ultrasound to propagate through the water column, providing a controlled, consistent environment that significantly reduces dead zones and improves data integrity.

With a wide electronic footprint and optimized beam coverage, these phased array probes significantly reduce scanning time while collecting high-quality, detailed data. This system is ideal for corrosion mapping applications, allowing for faster inspection speeds without compromising image quality or defect characterization.

Eddyfi Technologies’ automated scanners for corrosion mapping are built on robust, field-proven technology.

Magnetic

The battery-operated, modular and scalable system can deploy a range of PA & UT techniques for pressure vessel, storage tanks, pipelines, spheres, ship hull and other critical assets.

The steerable tractor units incorporate powerful magnetic drive wheels ensuring the scanner remains fixed to the inspection surface even while inverted making it ideal for assets ranging from 76.2mm (3in) OD to flat plate.

This system can only be used for single line corrosion scans.

Non-Magnetic

The battery-operated, chain driven versatile system is best suited to non-ferrous surfaces such as Glass Fiber-Reinforced Plastic (GFRP or GRP), Carbon Fiber-Reinforced Plastic (CFRP or CRP), High Density Polyethylene (HDPE), plastic and others. The system operates flawlessly on ferrous surfaces with diameters ranging between 15.24 and 106.7cm (6 and 42in).

This versatile solution delivers high-performance in a variety of Non-Intrusive Inspection (NII) applications, helping customers achieve critical integrity assessments with minimal downtime and reduced operational costs.

A key differentiator of these system is the ability to deliver up to a 9:1 cost savings compared to traditional Internal Visual Inspection (IVI) methods, by reducing the need for extensive cleaning or radioactive waste disposal. Eddyfi Technologies offers a toolbox of solutions to maximize inspection efficiency and Probability of Detection (PoD), including:

• Ultrasonic corrosion mapping (capable of operating at up to 150°C / 302°F)
• Phased array ultrasonic testing corrosion mapping
• 1-Axis single line UT/PAUT scanning for more focused inspections

Automated corrosion mapping has become an integral part of Non-Destructive Testing (NDT) campaigns, widely adopted across integrity management programs and written schemes of examination. While traditional corrosion mapping systems often rely on a coarse resolution—typically collecting data points every 3 to 5mm (0.12 to 0.20in)—Eddyfi Technologies’ advanced scanner solutions are engineered to optimize productivity while delivering precise, high-resolution data, improving both the speed and accuracy of inspections.

Eddyfi Technologies' automated scanners are equipped to detect a wide range of defects, including:

• General corrosion and erosion
• Microbial Induced Corrosion (MIC)
• Hydrogen Blistering (HB)
• Laminations and inclusions

These solutions provide quantifiable, detailed defect characterization, enhancing inspection accuracy while increasing productivity. With high-resolution capabilities, you no longer need to sacrifice precision for speed.

Ultrasonic Corrosion Mapping

Eddyfi Technologies’ recommended conventional ultrasonic testing solution, when paired with an automated system, utilizes a single crystal focused probe with a local immersion water column, housed in a gimbaled holder. This setup ensures stable coupling and high-quality data acquisition, even in challenging environments.

One key advantage of this approach is that advanced corrosion mapping surveys can be performed without the need for phased array-qualified personnel. Despite this, it still delivers the high productivity, high PoD, and application-specific software features associated with more advanced systems. Twin crystal UT options are also available, further enhancing versatility.

The gimbaled probe holder design is particularly beneficial for assets with surface irregularities, such as storage tanks and ship hulls, where plate undulations are common. For users of Eddyfi Technologies’ automated solution, selecting Phased Array Corrosion Mapping (PACM) as the primary inspection method and adding the Single Crystal Ultrasonic Testing (SCUT) probe kit ensures comprehensive data coverage, even in the most difficult inspection scenarios.

With such a versatile and scalable system, there are many options available to tailor to your precise requirements. Multiple probe kits, umbilical lengths up to 60m, a range of corrosion probe holders, HD cameras and a range of raster arm lengths, this truly is the most advanced and versatile system of its kind on the market.

Interchangeable bridges ensure the system adapts to new requirements, allowing additional sizes to be incorporated throughout the product lifecycle, these range from 300mm (12in) to 1160mm (46in).

• 300mm (11.8in): Perfect for areas with limited access, such as vessel heads, or where smaller scan widths are necessary.
• 600mm (23.6in) and above: Ideal for high efficiency scanning of larger surfaces, including tank shells and pipelines.

One-Axis Corrosion Scanning

Eddyfi Technologies’ versatile automated system, when paired with one of our industry-leading PAUT instruments, enables efficient one-axis (single line) corrosion surveys. This system offers flexibility by allowing various probe holders to be mounted directly to the pods (crawler body), providing a streamlined solution for inspecting assets where a full raster scan may not be required.

This method serves as a highly effective alternative to the Scorpion2, particularly when an irrigated UT or PAUT approach is preferred for corrosion mapping. With this one-axis solution, users can conduct targeted, precise inspections on assets like storage tanks and pipelines, while benefiting from the high PoD and productivity that Eddyfi Technologies’ advanced inspection tools are known for.
