MECHANICAL CHARACTERIZATION AND DEFECT ANALYSIS OF NATURAL GAS PIPELINE STEEL TOWARDS HYDROGEN INJECTION
T.E.F. SilvaGrand Ballroom C
Repurposing of natural gas infrastructure towards hydrogen injection implies its mechanical viability assurance. This study focuses on the structural integrity assessment of vintage steel API 5L Grade B (used in natural gas infrastructure), especially in what concerns the ductility loss due to hydrogen embrittlement and its effect on common damage occurrence, such as plain denting.
