Integrated system for quantitative real-time monitoring of hydrogen-induced cracking in simulated sour environment
First Claim
1. A system for monitoring hydrogen-induced cracking in a laboratory environment, comprising:
- a source of sour gas;
a test solution tank comprising a test solution and into which the sour gas is introduced such that the test solution becomes saturated with the sour gas;
a test cell defining a semi-open fluid vessel, the fluid vessel being in fluid communication with the test solution tank such that the fluid vessel receives the saturated test solution;
a test cell holder configured to rotate the test cell;
at least one specimen port operatively connected to the fluid vessel and configured to hold a test specimen such that one surface of each test specimen is exposed to the saturated test solution; and
an ultrasonic transducer operatively connected to the at least one specimen port and configured to rotate to scan HIC defects of the test specimen.

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 H2S 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.
