Fatigue Performance of High-Strength Pipeline Steels and Their Welds in Hydrogen Gas Service

Ronevich, Joseph A.; Feng, Zhili F.; Slifka, Andrew S.; Amaro, Robert A.; Song, Eun J.; Wang, Yanli W.

Objectives of the project include: Enable the use of high strength steel hydrogen pipelines, as significant cost savings can result by implementing high strength steels as compared to lower strength pipes. Demonstrate that girth welds in high-strength steel pipe exhibit fatigue performance similar to lower-strength steels in high-pressure hydrogen gas. Identify pathways for developing high-strength pipeline steels by establishing the relationship between microstructure constituents and hydrogen-accelerated fatigue crack growth (HA-FCG)
