Cryogenic Liquids – Insulated Cargo Tank Specifications. Cryogenic liquids—liquids having a normal boiling point below -130°F at 14.7 psia (-90°C at 101 kPa, abs.)—fall under unique considerations as they are kept in their liquid state at extremely low temperatures.
In the United States, specifications for cargo tanks carried by motor vehicles fall under 49 CFR. In particular, 49 CFR 178.320 covers general requirements applicable to all Department of Transportation (DOT) specification cargo tank motor vehicles.
Cryogenic liquids—liquids having a normal boiling point below -130°F at 14.7 psia (-90°C at 101 kPa, abs.)—fall under unique considerations as they are kept in their liquid state at extremely low temperatures.
Today, more and more of these industrial gases are being delivered to customers in liquid form at cryogenic temperatures, enabling them to be stored on site for later use. The tanks range in capacity from 3,000 to > 100,000 litres and come with standardised working pressures of 18, 22, or 36 bar respectively.
