Abstract
A method for the in situ measurement of atomic hydrogen permeation into carbon steel from process streams under operating conditions of up to 3000 psi and temperatures up to 300° F. includes providing a probe assembly that includes a test specimen electrode and a negatively charged counter electrode in a fluid-tight reservoir containing an electrolyte, mounting the probe assembly directly in contact with a process stream and passing electrical conductors from the probe through a supporting, electrically non-conductive isolator positioned between a mounting assembly and the probe; maintaining a constant voltage across the electrodes and thereby directly measuring and recording permeation current flow between the probe electrodes.
