| Abstract: | The study estimates the residual lifetime of pipelines with axial semi-elliptical cracks on their outer surfaces, revealing a significant decrease in lifetime with higher hydrogen concentrations in the metal. It also demonstrates that more elongated semi-elliptical cracks pose greater danger compared to deeper defects, highlighting the criticality of considering defect shape in assessing pipeline integrity. Overall, the findings underscore the importance of monitoring hydrogen concentrations in pipeline metals to mitigate risks associated with crack propagation and potential failures. |
