Time Dependence of Hydrogen Induced Cracking of X70 Pipeline Steel under Severe and Mild Sour Service Conditions using Ultrasonic Analysis
Download2020-01-01
Gawor, S., Wiskel, J.B., Ivey, D.G., Liu, J., Henein, H.
A standard NACE hydrogen induced crack test was used to evaluate the resistance of two compositions of X70 steel (X70-X (Ca/S ratio of 2.5) and X70-B (Ca/S ratio of <0.5)) under severe (pH = 2.7 and 100% H2S) and mild (pH = 5.5 and 100% H2S) sour service conditions. An ultrasonic technique was...
