- Abstract
Objective To investigate the effects of hydrogen charging on the hydrogen damage behavior of tubes in sour gas environment, the tensile mechanical properties of three high-strength steels before and after hydrogen charging should be evaluated. Methods The hydrogen damage behavior of the three high-strength steels was investigated by electrochemical hydrogen charging experiments, MTS tensile testing and fracture microscopic morphological analysis. Results The results showed that the tensile mechanical properties of the three steels were significantly reduced after hydrogen charging, indicating that plastic damage occurred in all three steels, and the greater the strength of the steel, the greater the reduction; and the stronger the hydrogen embrittlement of material, the lower the hydrogen damage resistance of material. Conclusion The hydrogen damage evaluation method for high-strength steel used in this article can provide a technical reference for evaluating the suitability of oil well pipes in sour gas environment.
