Cryogenic tanks are used cryogenic liquids. Cryogenic liquids are typically liquefied gases at -196 °C or lower. Common products include:
Liquid oxygen LOX / Liquid nitrogen LN,LIN / Liquid argon LAR / Liquid carbon dioxide (CO2)
Cryogenic tanks are thermally insulated, typically with a vacuum jacket, designed and manufactured to a high specification following international design codes. They can be fixed, mobile or transportable.
Storage tank capacity can be between 1-100 m3 ( vertical or horizontal )
Transport tank capacity can be between 30 - 60 m3
The inner vessels of cryogenic tanks are typically constructed of stainless steel,the outer vessels of the cryogenic tanks are fabricated from carbon steel, to provide vacuum insulation for the inner vessel.
The maximum allowable working pressure of the cryogenic stationary tanks for cryogenic liquefied gases such as liquid nitrogen, liquid oxygen, liquid argon and liquid natural gas ranges between 2 bar and 37 bar depending on application.
