Pipeline Things

Would you expect MFL to outperform ultrasonics on identifying selective seam weld corrosion? Hold off on sending your salty review emails for now.

In this episode of Pipeline Things, Rhett and Christopher sit down with returning guest Tom Bubenik and first-time guest Zach Booth of DNV to unpack IPC 2026-186359, a study of how ILI tools such as MFL and ultrasonics detect, identify and size selective seam weld corrosion.

Together, they walk through the 104 manufactured defects, the vendor feedback loop, and the paper’s most surprising conclusions. Tune in to hear why one tool run shouldn’t define a whole technology.

Highlights:

The process of manufacturing 104 realistic SSWC defects with varying depths on vintage pipe

Why the project should be viewed as "research initiative for ILI tool identification capabilities, rather than a judgement on performance validation"

How accurate sizing of defects like SSWC hinges on effective identification, and vendors performed better than those that didn’t tweak their analysis around identification criteria

Why the acoustic results came from just one EMAT and one UTCD run
