In this research, the effect of important parameters on hydrogen affected fatigue failure in
pipeline steel was studied in detail through literature review. It was found that several …

Hydrogen embrittlement of line pipe steels in the natural gas transmission and distribution
network is investigated. The objective is to assess whether the existing network can be used …

Steel pipelines will likely be employed extensively to transport gaseous hydrogen in support
of a future clean energy economy. To date, a hydrogen-specific cost analysis of pipeline …

In this work, the hydrogen fatigue of pipeline steel X60, its girth welds and weld defects were
investigated through in situ fatigue testing. A novel in situ gaseous hydrogen charging …

A cyclic cohesive zone model for predicting hydrogen assisted fatigue crack growth is
proposed, in which the degradation of cohesive strength and accumulated cohesive length …

Abstract Hydrogen-Affected Fatigue Crack Growth (HAFCG) in commercially pure iron has
been characterized in terms of hydrogen gas pressure, loading frequency and stress …

This review summarizes the thermodynamics of hydrogen (H2) in mixed gases of nitrogen
(N2), methane (CH4) and natural gas, with a special focus on hydrogen fugacity. A …

Hydrogen has been proposed as a potential partial solution to the need for a clean-energy
economy. In order to make this a reality, large-scale hydrogen transportation networks need …

In this study, the susceptibility of API X70 weld joints to hydrogen gas was investigated using
slow strain rate tensile (SSRT) tests. The microstructure of the subregion of the actual heat …

There is an increasing interest in ensuring compatibility of existing natural gas infrastructure
with conveyance of hydrogen, especially for vintage (pre-1970s) pipeline steels. While …
