RP3.1-10: Hydrogen embrittlement of pipeline steels, subcritical and critical crack growth
This project elucidates the hydrogen embrittlement manifestations of gas pipeline steels by using electrolytic (cathodic) hydrogen charging combined with mechanical testing.The research addresses the current knowledge gaps around the sub-critical crack growth (formation) and critical crack growth (initiation) of steel pipes in hydrogen environemnt. The research evaluates:

|Commencement / End Date||August 2020 to October 2024|
|Outcomes / Impact||
Gas transmission pipeline operators need to know the safe operating conditions for pipelines carrying hydrogen – in particular, the permissible safe pressure, and tolerable defect sizes. Otherwise unexpected fractures can occur, with significant collateral damage.The project contributes to the determination of the safe operating limits of gas pipelines, and may allow for a less conservative approach than current standards for operation of hydrogen pressure vessels.
