Pits-in-Pits
Pipeline operators consistently rank pits-in-pits as a top integrity threat to their pipelines, yet most pipeline integrity assessment methods can’t detect these anomalies effectively. Ultra-High Resolution (UHR) ILI technology from ENTEGRA® enables better visualization of these potentially critical areas of corrosion, while our experienced analysts make sense of the meaning behind the data, so you can make more informed and cost-effective decisions.
Pits-in-pits are a special kind of complex corrosion, where deeper pinhole-shaped anomalies are embedded within larger areas of shallow metal loss. UHR ILI from ENTEGRA is capable of seeing these anomalies in greater detail to reveal their true complexity, allowing us to detect and characterize individual embedded pinhole anomalies down to 3 mm in size.
Other modern MFL data would likely consider this a single anomaly, potentially missing its deepest feature.
The clarity of our UHR data is 4x or more the resolution of other MFL vendors, allowing us to see so much more of your pipeline. Here, we zoom in to the area of the yellow box to create the profile of pits-in-pits along the long seam, with a 3D profile rendered below.
The robust technology deployed on our advanced UHR ILI tools is always examined by our experienced data analysis teams, to put anomalies like these into context with your operational specifics. With a more detailed understanding of pits-in-pits, you can choose an effective course of action to manage your pipeline integrity, whether that’s adding an area to a watchlist or scheduling a timely repair.
It is crucial to have the right technology, and the right team, on your side when approaching these potentially consequential anomalies.

The clarity of this data, zoomed in from the yellow inset box pictured above, is possible only with ENTEGRA’s Ultra-High Resolution technology. Here we see clearly a deeper pit (dark red) in an area of lighter metal loss (orange/yellow).
