Automatic Data Acquisition ch Multi Array Intelligent ECT
The Intelligent ECT probe has been developed to achieve high speed inspectio n and high flaw detectability compared with conventional ECT probe. Intellig ent ECT probe has 24ch multi array coils which consist of inclined drive coi ls and thin-film pick-up coils and has various diameter types for inspectio n of various steam generators. In Japan, Intelligent ECT has been applied to 100% full length inspection of actual plants with fully automatic data acqu isition system. The Intelligent ECT has been applie...

ECT Eddy Current Intelligent ECT Steam Generator
Intelligent ECT system for 7/8 inch tubes has been qualified as official method for inspection of Steam Generator tubes in Japan since 2003. We have developed Intelligent ECT system for 3/4 inch outer diameter tubes, which is applicable for full length inspection of all tubes in Steam Generator. We have carried out the verification test on passage, scanning speed, detectability of various defects, performance of auto screening, effectiveness of filtering, and accuracy of depth sizing of wears. Totally...

Dissimilar metal weld ECT testing Nickel-Alloy steel welding PWR RV SCC SG
Eddy Current testing (ECT) for detecting stress corrosion cracks (SCCs) in the vessel's dissimilar metal weld of PWR plants was carried out. Appropriate ECT with a single cross-coil can detect shallow artificial SCCs with depth of 0.5mm or over. And magnetic saturation method is very effective for decreasing noise signals come from permeability change in the boundary region between overlay and buttering of safe-end....
