Hydrogen, clean, efficient and zero-carbon, is seen as a most promising energy source. The
use of existing gas pipelines for hydrogen–natural gas transportation is considered to be an …

In this paper, hydrogen diffusion behavior in pipeline steel is thoroughly investigated. The
effect of various microstructural factors affecting hydrogen diffusion are discussed using …

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 …

The microstructural features that favor hydrogen-induced cracking (HIC) in internal, middle,
and external layers of pipeline steels were investigated. The electrochemical cathodic …

This study reported the significant influence of Ta on hydrogen-induced cracking of pipeline
steels. It was found that with decreasing TaC size, the hydrogen diffusivity of steels was …

Hydrogen as an energy carrier plays an important role in achieving the ambitious climate
targets associated with decarbonization. The main challenge is to ensure safe transport of …

Highlights•Hydrogen permeation with chemical and electrochemical charging was
conducted.•The surface effect model to analyze the adsorption and desorption of hydrogen …

Although hydrogen embrittlement (HE) has been the subject of extensive research over the
past century, a systematic study on the HE susceptibility of steels under different …
