Description

technical field

[0001] The invention relates to the technical field of material mechanical property testing equipment development, in particular to an intrinsically safe high-purity high-pressure hydrogen environment material compatibility test system, and also relates to an intrinsically safe high-purity high-pressure hydrogen environment material compatibility test method. Background technique

[0002] Hydrogen storage and transportation is an important link in the development of hydrogen energy industrialization, and hydrogen storage at room temperature and high pressure is currently the dominant hydrogen storage method in industrial applications because of its simple equipment structure and fast filling speed. However, long-term service in the high-pressure hydrogen environment will face hydrogen embrittlement problems such as reduced plasticity and accelerated fatigue crack growth rate, which will seriously endanger the operation safety of the hydrogen energy storage and...
