LABORATORY APPARATUS FOR HYDROGEN PERMEATION ELECTROCHEMICAL MEASUREMENTS UNDER HIGH PRESSURE, TEMPERATURE AND TENSILE STRESS

Abstract: a system for performing electrochemical and hydrogen permeation measurements using a test specimen subject to tensile stress comprises a first housing filled with a process fluid supplied via an inlet with hydrogen sulfide, a second housing filled with a basic solution, a test specimen positioned between the first and second housings exposed to the process fluid on one side and to the basic solution on the other, first and second potentiostats coupled to the first and second housings to measure corrosion and induce hydrogen permeation, a loading device adapted to apply a longitudinal strain on the specimen, and a computing device configured to control operation of the potentiostat and loading device. the hydrogen sulfide in the process fluid impedes formation of diatomic hydrogen from atomic hydrogen, allowing adsorbed atomic hydrogen to enter into the steel test specimen from one side and permeate into the other side of the test specimen.
