Integrated system for quantitative real-time monitoring of hydrogen-induced cracking in simulated sour environment

A method for monitoring hydrogen-induced cracking in at least one test specimen, comprising:

• saturating a test solution with a gas comprising H2S;
• delivering the saturated test solution into a test cell, wherein the test cell comprises at least one specimen port and at least one test specimen, the at least one specimen port being configured to receive the at least one test specimen;
• exposing the at least one test specimen to the saturated test solution, wherein only one surface of each specimen is exposed to the saturated test solution;
• and
• scanning the at least one test specimen with at least one-ultrasonic transducer at two or more time points, wherein each of the at least one ultrasonic transducers is operatively connected to one of the at least one specimen ports opposite the surface of each specimen exposed to the saturated test solution, and wherein each of the at least one ultrasonic transducers is configured to rotate completely around a symmetry axis normal to the surface of the test specimen to complete each scan.
