Materials Solutions for Hydrogen Delivery in Pipelines
Currently the most economical method for transmission of hydrogen gas at large volumes is under pressure through transmission steel pipelines. As transmission pressures are increased, steel pipelines that could be used for the transport of hydrogen at pressure can be prone to hydrogen embrittlement at the welds, the heat-affected-zone and/or the base metal regions of the pipeline. Over the past few years, significant advances have been made in understanding the mechanisms of hydrogen embrittlement in a wide variety of materials and in materials technologies. This project evaluated hydrogen embrittlement characteristics of existing commercial pipeline steels under high-pressure hydrogen range. Evaluation included microstructural characterization and mechanical property testing. Testing included: tensile testing in the presence of gaseous hydrogen under pressure various pressures; fracture testing in the presence of gaseous hydrogen under pressure various pressures; and fatigue testing in the presence of gaseous hydrogen under pressure various pressures.
