Cryogenic tanks are containers designed for the storage and transportation of cryogenic liquids (such as liquid nitrogen, liquid oxygen, liquid argon, liquefied natural gas). They are made of high-strength materials and equipped with multi-layer insulation and temperature control systems to ensure the stability of liquids at extremely low temperatures. Cryogenic tanks are widely used in the fields of petrochemicals, energy, medicine and scientific research to ensure the safe and efficient storage and transportation of cryogenic liquids.
