Shell & Tube Process


Most of the industrial processes require heat exchanger equipment and miscellaneous pressure vessels. The great variety of industrial processes and applications require a wide capability of performing complex thermal and mechanical design as well as the capacity and experience in manufacturing heavy equipment made of special materials to withstand demanding operating conditions.

Shell & Tube equipment is a very wide category of products that are suited for very simple storage tanks for low pressure and low temperature applications to complex reactors for high demanding applications.

The most common processes in the Oil & Gas, Petrochemical & Chemical, Food & Beverages and Heavy & Light Industry require a significant number of equipment to exchange heat or to storage different fluids or components. For all of them we have a specific solution.

We offer highly specialized thermal and mechanical design resources as well as manufacturing capabilities to produce everything from very simple equipment to large and heavy equipment made of thick and high grade materials.

With our product portfolio we offer: pressure vessels, heat exchangers, reactors and columns of any kind for any purpose.

Most of the industrial processes need to store fluids and materials of different kinds and with different purposes.

Kelvion offers a wide range of pressure vessels:

• Storage vessels
• Heated vessels
• Mixing vessels
• High pressure vessels

Materials to be used are normally carbon steel, low and medium alloyed steels and stainless steel.
The most frequent design codes are ASME  and ADMerkblatter.

Especially the processes for the oil & gas as well as the chemical market need to separate different components usually based in different evaporation temperatures. This separation is done in distillation or fragmentation columns.

These columns are usually quite complex equipment, with large dimensions, heavy weights and a complex construction to host the process trays and to allow a proper fluids separation.

We have a wide experience in providing this kind of equipment worldwide, fulfilling the most strict requirements and specifications.

Reactors are vessels designed to receive different reactants or substances that change their mechanical and chemical properties after a chemical reaction.

We have the capability and skills to design and manufacture:

• Batch reactors
• Continuous stirred-tank reactors
• Plug flow reactors
• Catalytic reactors

Due to the severe conditions that most of this equipment works under, they are made of high grade materials, Titanium, Ni and other complex materials.
