In the shaped section there formed is one or more steps passing in a circumferential direction relative to longitudinal axis. Each step provides increase of the distance along the radius of the shaped section from longitudinal axis. The steps form at least two parts of the side wall, which have different distances radially from longitudinal axis.

EFFECT: increase of working volume inside the drum at the same total volume of the tank, and decrease of the drum vibration value.
