When the capacity of the tanker is not large, the entire container is treated as a single compartment. If the capacity of the tanker is large, the inside of the container needs to be divided into several independent single compartments by bulkhead.  The buikhead is mainly made of alumium for tanker.

Because when the vehicle is running, there is a certain gap or not full in the oil tank truck, and the liquid fluctuates back and forth, left and right in the container, which will cause drastic changes in the axle load of the tank truck, which will seriously affect the stability of the tank truck. Separating the large-capacity liquid tank into several single chambers can improve the above situation, and it can also carry several different liquid cargoes on the same tanker at the same time.
