Non-intrusive pressure and corrosion monitoring device

The proposed non-intrusive corrosion monitoring technology uses Force Sensitive Sensors (FSS) externally mounted in contact with the surface of a pipeline. FSS detect pipe expansions due to changes in internal pressure. The measured force due to the pipe's radial deflection is proportional to the pipe's remaining wall thickness. As corrosion occurs and wall thickness decreases, the measured force increases. The wall thickness is determined by comparing the pressure change to average readings from other sensors. The technology allows for continual data collection from large surface areas without costly inspection. It combines monitoring of representative areas like manual inspection with uninterrupted monitoring. A prototype has been developed and proof of concept testing completed. Theoretical concept validation by Glasgow Caledonian University confirmed the capability to detect internal pressure and changes in wall thickness. The technology is currently at Technology Readiness Level 4 with a patent application submitted.
