Usage
Tank containers are used for liquid cargoes, such as:
- Foodstuffs: fruit juices, spirits, sweet oils
- Chemicals: hazardous materials, such as fuels, toxic substances, corrosion protection agents
Description
Tank containers must be at least 80%% full, to prevent dangerous surging of the liquids in transit. On the other hand, they must not as a rule be over 95%% full, or there will not be sufficient ullage space for thermal expansion. The extent of thermal expansion may be calculated for each cargo on the basis of the following formula:
ΔV = Va · γ · ΔT
Ve = Va (1 + γ · ΔT)
ΔV : change in volume
Va : volume at initial temperature a
Ve : final volume at temperature e
γ : coefficient of cubic (thermal) expansion
ΔT : temperature difference in degrees kelvin
Tank containers intended for transporting foodstuffs must be labeled "Potable Liquids only".
Some hazardous materials must be transported in tank containers with no in- or outlet openings below the surface of the liquid.
Tank containers are generally designed for an operating pressure of up to 3 bar (above atmospheric). The test pressure used is 4.5 bar (above atmospheric).
If the cargo requires temperature-controlled transport, tank containers can be equipped with insulation or heating. The temperature of the cargo may be precisely controlled using temperature sensors.
