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

Abstract

The present disclosure is directed to a method and system for monitoring hydrogen-induced cracking in at least one test specimen. The method includes the steps of: saturating a test solution with a gas comprising HS and 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 specimen port is configured to receive the test specimen. The method also includes the step of 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 the step of scanning the test specimen with a ultrasonic transducer at two or more time points, wherein the ultrasonic transducer is operatively connected to the specimen port and configured to rotate completely around the symmetry axis of the test specimen to complete each scan.
