Theoretical and experimental contributions on ultrasonic contactless examination of underground pipes through which pressurized fluids circulate

Abstract In any civil or industrial construction, there are many embedded pipelines through which pressurized fluids or gases are circulate and which, over time, are subject to corrosion. Examination and monitoring of corrosion/erosion process in order to determine the service life of pipelines through which fluids circulate at different temperatures and / or pressures is a particularly important task for both the designer and the owner because knowledge of “health status” of these in time is extremely. On-site ultrasound control of wall thickness is based on simple propagation time measurements and is typically used to evaluate corrosion and erosion. The paper presents a non-destructive co…
