氦储运技术研究进展OACSTPCD

Helium plays a crucial role in various sectors,including national defense and the high-tech industry,making storage and transportation of helium pivotal to the industrial chain.The development of helium storage and transportation technology,along with the design and manufacturing of associated equipment,is essential for the growth of helium industry.Helium storage and transportation are categorized into gas and liquid phases.This study covers different storage methods for gaseous and liquid helium:gaseous helium is primarily stored above ground under high pressure and in underground helium storages,while liquid helium is stored at low temperatures and pressures.This paper elaborates on storage and transportation equipment,including multi-layered wrapping storage tanks,tube bundle,liquid helium tank,and liquid helium Dewar flasks.It is concluded that large-scale,long-distance transportation predominantly utilizes liquid helium as the transportation medium,whereas high-pressure helium gas is more suitable for small-scale transportation.Finally,the future development directions for helium storage and transportation equipment are discussed.
