Probe for the continuous in-situ measurement of the corrosion rate of pipes at high temperature or having high resistivity liquids flowing therethrough.

摘要

The invention relates to a probe (10) for the continuous in-situ measurement of the rate of corrosion of pipes subjected to high temperatures or having highly resistive fluids flowing therethrough, by a measurement of the polarization resistance, characterized in that it comprises : electrodes of tubular form (17) one of which is the working electrode, adapted to provide an extension of a pipeline (13, 14), said electrodes, being alternately spaced apart with dielectric spacers (18), means for connecting said electrodes to said pipeline between two sections of the pipeline, and resilient or nearly resilient gaskets (23, 22) to provide sealtightness between said electrodes, spacers (18), connectors and pipe sections.
