Method and apparatus for the detection and measurement of corrosion

摘要

The invention relates to a process and a device for detection of the corrosion by stitching. / p & & p & it relates to a process and an apparatus according to which the rate of loss of material of an element 2 is determined on the one hand, by measuring the variations of the electrical resistance of this element 2 and, on the other hand, by measuring the activity of the downstream side of this element 2. When the speeds of removal measured of material by the two techniques are different, they indicate the presence of a corrosion by stitching. / p & & p & application is the determination of the corrosion of the ducts and the top plug.
