摘要： A method of tracking the rate of corrosion of a metal conduit traversed by a corrosive fluid, in which is provided a device arranged so as to form, when said device is installed on a wall of the metal conduit, a chamber able to receive gaseous hydrogen issuing by permeation across said wall of said conduit, the method comprising: (i) a step of treatment to eliminate a metallic species from the chamber, (ii) a step of measuring a quantity of hydrogen received in the chamber, with a view to estimating the rate of corrosion of the metal conduit.
