Measuring Crack Defects with Sub-Millimeter Accuracy

Ultrasonic crack technology, using piezoelectric transducers, is a proven and widely used solution for crack and crack-like defect detection in liquid pipelines. Over the past 20 years, only minor developments, and improvements in this area were offered to pipeline operators. After two decades of incremental improvements, technology-related limitations still prevent accurate sizing of defects.

This white paper will focus on the recent technical developments at NDT Global which have successfully overcome several of these limitations.
