The in-line inspection device for detecting cracks and crack-like defects, UltraScan CD, has inspected more than 700 miles of operating oil and gas pipelines. Comparison of the predicted vs. actual detection results by excavation illustrates the inherent detection and characterization accuracy. The detection threshold for individual cracks has been verified to be a depth of ,1 mm and a length of <30 mm, in addition sizing of defects has also been found to be reliable. The current range of UltraScan CD tools is 22--56 inches, Pipetronix is planning to expand its range by developing some smaller bore tools. To date, 41 excavations have been performed on pipelines inspected with the UltraScan CD. The findings proved out to be SCC, cracks, weld damage and some crack-like defects (e.g., scratches and grooves). The excavations showed that the sensitivity of the tool is such that even cracks and crack-like defects with depths below 2 mm are detectable.
