Containers

Ellipsoid and pseudo-ellipsoid. Containers of this shape are manufactured from flat, thin and round metal sheets by compression moulding (mostly cold deformation). External container measurements comply with DIN 28011, DIN 28013, PN-64/M-35411, PN-75/M-35412 standards, or can be of a non-standard shape. This is the most common shape of pressure containers.

Conical. A metal sheet is shaped to a cone with the incidence angles, varying from 15° to 20°. Where the unloading is prioritised (containers for bulk or high-viscous substances), the container's exterior part is formed with a higher incidence angle. This shape is common for low operating pressure containers.

Flat-bottomed. Made from a flat, thin and round metal sheet with the edges bent in different height (mostly from 15 to 30 mm, depending on the container diameter). Flat-bottomed containers are not very robust, as a result of which the flat bottom is usually chosen for lower capacity containers, where there is no need to maintain overpressure nor sub-atmospheric pressure. In cases where the container space is insufficient to install a draining valve, instead a flat-shaped bottom sloping towards the outlet valve would facilitate a full drainage.

Stationary containers are installed in permanent locations and cannot be transferred.

Mobile containers are suitable for short-distance transfer from one manufacturing site to another. Usually the two front wheels are equipped with fixed blocking devices, whereas the rear wheels - with controllable blocking devices and a stopping mechanism, accordingly. In cases where a high degree of maneuverability is a priority, all controllable container wheels may be a good option. For easier transportation a tube handle is mounted at the ergonomic height on the side wall of the container.
