NDT Global’s ultrasonic metal-loss-inspection technology, the UMp tool, has detected an internal metal-loss feature in a girth weld of an oil pipeline.

The defect is thought to have originated during the pipeline’s construction in the 1970s.

The pipeline defect had a length of 6 mm in the flow or axial direction, while the width in the circumferential direction was 9 mm, with and the depth was 3.2 mm.

Investigations revealed that the anomaly was also visible on the x-ray film from the affected girth weld taken during construction.NDT Global used its UMp and UMp+ technology to accurately detect and size metal-loss features down to 5 mm in diameter, even in girth welds.

The high axial and circumferential resolution of the pitting configuration enabled a precise measurement grid.
