R-Scan Array

11
Introducing R-Scan Array
R-Scan Array PAUT system is the perfect solution for the inspection of complex geometry
components including curved surfaces, flat plate, pipelines, and restricted access areas. The
versatile, battery-operated, portable semi-automated Phased-Array (PA) corrosion mapping
solution with onboard data collection capabilities delivers improved inspection dexterity and
accuracy.
In conjunction with the RMS Phased Array solution from Eddyfi Technologies, the R-Scan Array
scanner allows for manually encoded Phased Array (PA) corrosion mapping with onboard data
stitching capabilities and Fully remote automated PA corrosion mapping.
The R-Scan Array system has been designed to work in conjunction with the cutting-edge
M2M Gekko and Mantis phased-array systems. M2M is the first brand to deliver portable phased-
array flaw detectors capable of driving matrix arrays and perform TFM in real-time.
Having this unique ability with a manual phased array scanner, allows operators to quickly
determine defect type and morphology and also navigate restricted and complex scanning
surfaces. Detection capabilities include corrosion, erosion, hydrogen-induced cracking (HIC), and
high-temperature hydrogen attack (HTHA) with quantifiable, detailed defect characterization,
allowing for complete coverage during complex inspection campaigns.
Phased-Array Corrosion Mapping
The phased-array configuration utilizes the 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 conformance and improved coupling.
R-Scan Array Operation Modes
The scanner can be used in both manual and automated capacities. When deployed as a portable
handheld manual Phased Array corrosion mapping system, the high friction wheels in conjunction
with the on-board control buttons provide the adhesion, friction, and stability to perform a stitched
C-Scan data set without needing to return to the instrument.
When requiring a remote and fully automated scanning solution, the high friction interchangeable
wheels are replaced by the low friction wheels for a smooth axial/lateral step for precision C-Scan
data stitching.
