Corrosion prediction based on the detection of temperature and fluids by fibre optics

The apparatus predicts the risk of corrosion of metal structures (10, e.g. a gas pipe). It comprises a temperature detector (11), and a fluid or moisture detector in the form of liquid absorbing material (13) wrapping a fibre optic detector (12), and a processor (30) to predict the corrosion risk ba...

Beschreibung
Zusammenfassung:	The apparatus predicts the risk of corrosion of metal structures (10, e.g. a gas pipe). It comprises a temperature detector (11), and a fluid or moisture detector in the form of liquid absorbing material (13) wrapping a fibre optic detector (12), and a processor (30) to predict the corrosion risk based on the information received from these detectors. The processor (30) may use prior knowledge of the corrodible material for such task. The metal structure may be surrounded by insulations, in this case, the temperature and fluid detectors may be arranged between the insulations and the metal structure. The detectors may include an optical fibre provided along the outside surface or arranged spirally around the outside surface of the structure.
