A buried operational pipeline in the Middle East, known to be at risk of localised corrosion, was equipped with gPIMS^® to monitor corrosion inhibitor effectiveness without repeated excavation.

Over one year, automated monitoring provided regular wall thickness measurements and large&8209;area condition data. Stable wall thickness readings indicated effective inhibitor dosing, while the detection and subsequent disappearance of sludge accumulation following pipeline cleaning demonstrated the system’s sensitivity to operational changes.
