Hydrogen is a carbon-free fuel that can facilitate the progress of achieving net-zero
emission. The use of the existing natural gas pipelines for hydrogen transport is an essential …

Several environmental challenges such as corrosion, low temperature, hydrogen-induced
cracking (HIC), stress corrosion cracking (SCC), sulfide stress corrosion cracking (SSCC) …

Hydrogen embrittlement is a serious threat to the safety operation for hydrogen blended
natural gas pipelines. To determine the critical safety hydrogen blending ratio, in-situ high …

In this paper the effects of hydrogen on the transport of natural gas-hydrogen mixture in a
high-pressure natural gas transmission system are investigated in detail. Our research …

In this investigation, the effect of microstructural changes and phase equilibria on corrosion
behavior and hydrogen induced cracking (HIC) sensitivity of an API X65 pipeline steel was …

The hydrogen compatibility of two X65 pipeline steels for transport of hydrogen gas is
investigated through microstructural characterization, hydrogen permeation measurements …

The presence of notches directly influences the material's degree of resistance to fracture, as
each notch is defined by its size and location in the structure. In this study, we present a …

In this work, we investigate the influence mechanism of hydrogen partial pressure on
fracture toughness and fatigue life of a high strength pipeline steel. Both fracture toughness …

Abstract Hydrogen-Induced Cracking (HIC) is a primary failure mechanism of pipeline-
welded joints in the absence of external loading in the oil and gas exploration industries …

This study consists of a statistical study to identify spatial distribution parameters of non-
metallic inclusions (NMIs) at hydrogen-induced cracking (HIC) nucleation sites in both low …
