Probe for the continuous in-situ measurement of the corrosion rate of pipes at high temperature or having high-resistivity liquids flowing therethrough
First Claim
1. A probe for the continuous in-situ measurement of the corrosion rate of pipes subjected to high temperatures or having highly-resistive fluids flowing therethrough, by measuring the polarization resistance comprisinga section of pipe,means to mount said section of pipe at the ends and in a path receiving therethrough at least some of the flow of the pipes whose measurement of corrosion rate is being made,said section of pipe includinga couple of electrodes of a tubular shape, one of which is the working electrode,dielectric spacers alternately spacing apart said electrodes,and resilient and nearly resilient gaskets to provide a tight seal between said electrodes, spacers, mounting means, and pipes.

Abstract
The invention relates to a probe 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 one of which is the working electrode, adapted to provide an extension of a pipeline, said electrodes being alternately spaced apart with dielectric spacers, means for connecting said electrodes to said pipeline between two sections of the pipeline, and resilient or nearly resilient gaskets to provide sealtightness between said electrodes, spacers, connectors and pipe sections.
