Inspection: UT/Wall Measurement

The Weatherford ultrasonic testing (UT) pipewall measurement tool uses high-frequency, highly directional compression sound waves to measure wall thickness, finding hidden flaws. This sophisticated device generates short bursts of sound energy for the detection and determination of metal-loss and manufacturing-type defects resident in the pipewall. These defects include metal-loss (corrosion) on the outer and inner surface, channeling, blisters, bulges, inclusions and laminations. The UT tool uses immersion-based ultrasound sensors for direct measurement of defects, monitoring and analyzing the reflected or transmitted wave patterns to determine the condition of the pipewall material.
UT is a direct measurement, supplying a more accurate description and characterization of anomalies. Detailed information is essential to correctly apply advanced assessment codes and determine the appropriate pipewall repair technology application. These tools can be used in onshore or offshore pipelines and are available in many different diameters.The Weatherford proprietary visualization and analysis software package, providing a detailed database of anomalies, pipeline features, and geometry anomalies—allows data to be viewed in various formats.

The software, anomaly database and analysis report (generated by the analysis center) are then compiled to form a comprehensive final report to document the integrity of the pipeline.
