Nondestructive Testing for SCC Crack Mapping and Depth SizingMWM-Array Scanners for SCC Detection through Coatings  Wide-area scanning arrays for preliminary screening of SCC through coatings (coal tar wrap, epoxy, etc.)  Scan rates over 20 sq. ft.min (1.86 m2 ) using JENTEK’s GridStation 8200 instrumentation MWM-Array Scanners for High-Resolution SCC Crack Mapping & Sizing  High-throughput C-Scan imaging of discrete cracks andor SCC colonies  Conformable MWM-Array eddy current sensors configurable for wide range of pipe diameters  Minimal surface preparation requirements (not affected by coatings, moisture and dirt) Crack Depth Software Module – JENTEK GridStation Software  Rapid conversion of MWM-Array response into depth measurements  Automatic crack interaction capability  Electronic storage and retrieval of measurement data (as potential MPI replacement)  Microsoft Windows™ environment with GridStation software for quick and easy report generation

• Pipe MaterialCarbon steel, including ASTM A106, ASTM A53, and API 5L.
• Pipe Diameter (Range)8.5 inch insulation diameter. For example: 4 inch pipe with >2.0 inch insulation 6 inch pipe with >1.0 inch insulation All larger diameters, including vessels
• Detection Threshold1 in. diameter at 65% wall loss (average) 2 in. diameter at 50% wall loss (average) 3 in. diameter at 30% wall loss (average) Based on 0.250" pipe wall, 2 inch insulation, aluminum WJ. Detection performance will vary due to pipe wall thickness, insul

The Leader in Eddy Current Testing PerformanceFast Corrosion Imaging for Piping, Vessels & Column Inspection  Light weight, ideal for rope access crews  Manual scanner with encoded C-scan imaging JENTEK Sensors recommends the non-integrated system (IN8200) for field services and the integrated system for special applications in the laboratory, or in certain situations where having an integrated version is preferred.
