What information is required to design and quote a custom industrial tank?

To correctly define a tank, it is necessary to know, at a minimum, the product it will contain, its density and viscosity, the required working capacity, the operating temperature, the expected pressure or vacuum, and the equipment’s function within the process. It is also advisable to indicate if the product requires agitation, heating, cooling, insulation, CIP cleaning, or a specific interior finish.
Location and access limitations are equally important: available space, maximum height, allowable diameter, passage through doors, transport to the plant, and the possibility of on-site assembly. With this data, a precise technical and economic proposal can be prepared, avoiding oversizing and subsequent changes.

What is the difference between a storage tank, a process vessel, and a reactor?

A storage tank is primarily intended to hold raw materials, intermediate products, or finished products. Its design focuses on capacity, product preservation, safety, and loading and unloading operations.
A process vessel, on the other hand, actively participates in a production phase and may incorporate agitation, temperature control, dosing, filtration, or instrumentation. A reactor is a specific type of process equipment in which a chemical or physico-chemical reaction takes place under controlled conditions of mixing, time, temperature, pressure, and composition.

How are the capacity and dimensions of an industrial tank determined?

Nominal capacity should not be chosen in isolation. The calculation must consider the working volume, safety or expansion space, minimum operating level, production cycles, inlet and outlet flow rates, and the plant’s potential future needs. For foaming products, fermentations, or processes with agitation, it may be necessary to reserve an additional margin.
The diameter and height are adapted to the available space, structural loads, the transport system, and the ease of cleaning and maintenance. For this reason, two tanks with the same capacity can have very different geometries depending on the process and installation conditions.

When is it better to manufacture a tank in the workshop versus building it on-site?

Workshop manufacturing is usually the most efficient option when the dimensions of the tank allow for its transport and access to the final location. It facilitates control of the manufacturing process and allows the equipment to be delivered with most of the accessories already installed.

On-site construction is suitable for large-scale tanks or when there are transport restrictions, limited access, or structural limitations at the plant. Assembly can be carried out entirely on-site or through a mixed system, with components pre-prepared in the workshop and assembled at the customer’s facilities.

How is the material and interior finish of a tank selected?

Material selection depends on chemical compatibility with the product, concentration, temperature, pressure, cleaning frequency, and the hygienic requirements of the sector. Stainless steel is common in food, beverages, chemicals, cosmetics, and pharmaceuticals due to its resistance, durability, and ease of cleaning, although each application must be studied specifically.

The interior finish is also defined according to the process. General storage may require a different finish than pharmaceutical or food equipment. Polishing, weld treatment, pickling, and passivation must be specified based on the level of cleanliness, contamination prevention, and required documentation.

What accessories can be incorporated into a stainless steel tank?

A tank can incorporate manways, covers, nozzles, valves, vents, filters, sight glasses, level indicators, temperature probes, load cells, pressure or vacuum systems, ladders, platforms, and safety elements. The configuration must respond to the product and the actual operation of the plant.

It can also be equipped with agitators, baffles, coils, heating or cooling jackets, thermal insulation, and CIP cleaning devices. Designing the tank and its accessories together helps avoid interference, hard-to-clean areas, and costly modifications during assembly.

Can tanks be manufactured for liquids, viscous products, and solids?

Yes. The design can be adapted for low-viscosity liquids, dense or pasty products, and bulk solids. In each case, the geometry, bottom type, inlets and outlets, discharge system, agitation, and necessary control elements change.

Viscous products may require inclined or conical bottoms, larger diameter outlets, heating, or specific agitators. For solids, aspects such as fluidity, bridging, abrasion, dust generation, and dosing are studied. The goal is to ensure stable filling, storage, and emptying.

When does a tank require thermal insulation or a heating or cooling system?

Thermal insulation is used when the product must maintain a stable temperature and there is a need to reduce heat or cold loss. It is common in food products, beverages, process water, oils, fats, and other materials whose viscosity or quality depends on temperature.

When maintaining the temperature is not enough, the tank can incorporate an active system using a jacket, half-pipe, dimple plates, or a coil. The solution is sized according to the energy to be transferred, the available time, the product properties, and the installation’s thermal fluid. In some cases, insulation is also used as a workplace risk prevention measure due to the high temperatures the steel can reach.
