Corrosion is estimated to cost production US$2.1 trillion per year. It is difficult and costly to inspect every pipe, pipeline and well for corrosion, especially with inaccessible or high-temperature assets. High-accuracy monitoring of pipe wall thicknesses is key to predicting asset lifetime and for appropriate maintenance planning, preventing such high-risk events and reducing costly downtime.
This work demonstrates, for the first time, the Novosound Belenus corrosion monitor measuring active galvanic corrosion, demonstrating the high-resolution capability of this broadband sensor. A wall thickness loss of 221 µm was measured on a flat calibration sample, validated as 270 ±40 µm using a depth gauge. A pipe wall thinning of 103 ±7 µm was measured on a more representative pipe sample.
