Abstract
Device for the detection of corrosion of the internal wall of a metal chamber. The device comprises at least one apparatus for measuring a physical quantity as a function of the condition of the surface of the internal wall of the chamber, such apparatus comprising a detection device having a detection surface and connected to an apparatus to measure and to calculate, and at least one means for transmitting these measurements, in which the detection surface of the detection device is applied to a surface element of the external wall of the chamber, the detection device being entirely covered by the casing isolating the chamber from the exterior environment. The device is particularly adapted for the inspection of and control of corrosion on the internal wall of conduits for transporting hydrocarbons which are buried in, or on, the sea floor.
