Hydrogen embrittlement of pipeline steels, subcritical crack growth and critical crack growth

R&D Focus Areas:
Pipeline materials and performance, Hydrogen embrittlement

Lead Organisation:
University of Queensland

Funding:
Future Fuels CRC

Status:
Active

Start date:
August 2020

Project summary description:
The research aims to elucidate the hydrogen embrittlement (HE) manifestations of gas pipeline steels based on recent research which has shown that the influence of hydrogen (for a large range of equivalent hydrogen pressures up to 2,000 bar) on steels can be determined by the use electrolytic (cathodic) hydrogen charging combined with mechanical testing. The proposed research addresses knowledge gaps identified in the “Future Fuels CRC Hydrogen in Pipelines Research Roadmap” focussing on sub-critical crack growth (formation) and critical crack growth (initiation).
