Annulus flooding detection system in flexible pipes using gamma rays transmission technique
Applied Radiation and Isotopes, 2022Flexible pipes are modular constructions made up of several layers. They are broadly employed in oil & gas industry, playing an important role in the Brazilian Pre-Salt production. Under specific conditions, seawater can ingress and this contact with metallic middle layers can significantly lead to a service life reduction of these layers, especially ...

Density measurement of multi-layered material using gamma-ray transmission technique
Radiation Physics and Chemistry, 2021Abstract The densitometry measurement based on the gamma-ray transmission technique of 3-layers material (tin, aluminum, and lead) has been newly developed and studied in this work. The concept and the calculation method were briefly described and the results of each material were compared with Archimedes's technique.
