Tender: Mechanical Tensile and Fatigue Testing of Palladium–Silver Membranes for Hydrogen Purification (400–500°C, up to 10 bar)

About

A procurement is seeking a supplier to undertake a programme of mechanical testing on palladium-silver membrane assemblies to generate design data supporting hydrogen purification systems for the STEP fuel cycle. The supplier must provide specialist facilities, equipment, technical expertise and personnel to perform slow strain rate tensile (SSRT) testing and strain-controlled fatigue testing under representative operating conditions at elevated temperatures of 400–500 °C in gaseous hydrogen at pressures up to 10 bar, and, where required, carry out in-situ hydrogen permeation testing before and during mechanical loading. The supplier will collect, analyse and report all test data, delivering comprehensive test reports with methodology, raw and processed data, analysis, observations and conclusions suitable for engineering assessment and future design activities; all testing must be carried out in appropriately equipped laboratory facilities with suitable safety, quality assurance and full traceability, and in accordance with recognised industry standards or agreed test procedures.
