Hydrogen energy,as a clean and efficient energy carrier,holds significant strategic importance in the global energy transition.However,the unique physical and chemical properties of hydrogen and liquid hydrogen pose severe challenges for material selection.This paper systematically analyzes the fundamental characteristics of hydrogen and liquid hydrogen,explores material failure mechanisms such as hydrogen embrittlement,hydrogen corrosion,and hydrogen-induced blistering,and summarizes key design considerations for hydrogen and liquid hydrogen pipeline materials,including corrosion resistance,compatibility,mechanical properties,and low temperature performance.Additionally,this paper conducts a detailed analysis of material strength calculations for hydrogen and liquid hydrogen pipelines,introducing the hydrogen induced material performance reduction coefficient to evaluate the impact of hydrogen media on material performance,and proposes calculation methods for pipeline wall thickness design.The research results provide a theoretical basis for material selection and strength design of hydrogen and liquid hydrogen pipelines,contributing significantly to the large-scale development of the hydrogen energy industry.
