TECHNICAL FAQs
About Cryogenic Tank
A cryogenic bulk tank is a vacuum insulated pressure vessel designed for the storage of liquefied industrial gases at extremely low temperatures. These tanks are commonly used for liquid oxygen (LOX), liquid nitrogen (LIN/LN2), liquid argon (LAR), LNG, and other cryogenic liquids in industrial gas supply systems.
Cryogenic storage tanks are commonly used for liquid oxygen (LOX), liquid nitrogen (LIN/LN2), liquid argon (LAR), liquefied natural gas (LNG), carbon dioxide (CO2), and other low-temperature liquefied gases used in industrial, medical, energy, and manufacturing applications.
Cryogenic bulk tanks are large stationary storage systems designed for continuous industrial gas supply, while cryogenic dewars are smaller portable containers used for low-volume storage, transportation, laboratory applications, and intermittent usage.
Cryogenic storage tanks are commonly manufactured according to ASME pressure vessel standards, CE/PED requirements, ISO quality systems, GB standards, and other project-specific international engineering specifications depending on application and export destination.
Most cryogenic tanks use high vacuum multilayer insulation systems designed to minimize heat transfer and reduce evaporation loss. Common insulation methods include vacuum powder insulation, perlite insulation, and multilayer reflective insulation technologies.
Liquid nitrogen storage duration depends on tank size, insulation quality, operating pressure, ambient temperature, and usage frequency. Properly designed vacuum insulated cryogenic tanks can minimize evaporation loss and support long-term liquid nitrogen storage.
Cryogenic bulk tanks are widely used in industrial gas supply, LNG infrastructure, medical oxygen systems, semiconductor manufacturing, food processing, chemical production, energy projects, aerospace, laboratories, and metal fabrication industries.
Cryogenic storage tanks are available in different pressure ranges depending on the stored medium and industrial application. Typical working pressures range from approximately 0.8 MPa to 3.5 MPa for industrial gas and LNG storage systems.
