Process and Storage Tanks

The tanks we offer may be freely configured with respect to the type of design or their equipment.

Classification of mixers with respect to the shape of the tank::

cylindrical (horizontal or vertical) – the simplest to produce
conical – with a quasi constant diameter-height ratio guaranteeing repeatability of its working parameters whatever the level of the substance fed.

Classification with respect to the shape of the bottom::

pressure-formed (ellipsoidal or pseudo-ellipsoidal) – made by the method of press forming (usually cold press forming) out of a disk-shaped metal sheet of various gauge. In our devices we use heads compliant with the DIN-28011; DIN-28013; PN-64/M-35411; PN-75/M-35412 standards or of a non-standard shape. These heads are most often used in pressure tanks
conical – made of a metal sheet in the form of a cone with various angles of inclination, ranging from 15° to 20°. When good discharge of a tank is a priority (e.g. in the case of loose materials or those of high viscosity), we use heads with a larger angle of inclination. The edges of heads are spinned at the R30 radius (or any other, as required by the end-user) in order to reinforce the structure and make it possible to butt weld the head to the jacket. If need be, the head may be flat, without any spinning. Conical heads are used in non-pressure tanks or those with low operating pressure.
flat – made out of a flat disk-shaped metal sheet with edges spinned at various radiuses (most often from 15 to 30 mm, depending on the tank diameter). Due to their relatively poor rigidity, these heads are used in low-capacity tanks which do not need to keep overpressure or subatmospheric pressure inside their chamber. Flat bottoms may be sloping towards the drain valve, so that the substance could be fully discharged even though there is not enough space under the tank for a typical drain valve to be installed.

Classification with respect to the number of jackets::

with one jacket – the simplest and thus the cheapest group of tanks. Used wherever thermal processing or thermal insulation is not required
with two jackets – the tank is covered by insulating material (mineral wool, foam, etc.) cased in a hermetically welded isolation mantle typically made of 1.4301 steel. Tanks with an isolation mantle are used when it is necessary to maintain a given temperature for a specified relatively short time during the production process or when a slight decrease in temperature is permissible
with three jackets – the most versatile but also the most expensive ones to build. Due to their heating (or cooling, or heating and cooling) jacket, they permit thermal processing of the product or maintaining its desired temperature by using a variety of media (e.g. steam, water, oil, chilled water). The design of the heating (or cooling, or heating and cooling) jacket depends on several factors, such as the tank capacity, working parameters (temperature, pressure), speed of heating up or cooling down, etc. Our Company applies the following types of heating and cooling jackets:
- “pillow-plate” jackets
- welded coils
- welded parallel tubes
- “cup-inside-cup” type (a uniform heating jacket over the entire surface of the main jacket).

Classification of tanks with respect to their functions::

With respect to the mode of operation::

Stationary tanks – designed to be installed at an intended location and not relocated in the course of the production process.

Mobile tanks – designed to be transported over short distances with the product inside them in the course of implementing a given technological process (e.g. they can be moved from one production room to another). The pillars of mobile tanks have wheel sets at their ends. Usually, the two front wheel sets are fixed, while the two rear ones are steerable with a fixing and braking mechanism. If good manoeuvrability is a priority, all the wheels of the tank may be steerable. For convenience of the person moving the tank, on the side wall of the device, at an ergonomic height, there is a tubular handle. Tanks of this type are usually part of a full set of lines dedicated to dry or loose forms, produced by Kates as self-contained facilities.
