Cleaning of tube bundle heat exchangers.

Cleaning of tube bundle heat exchangers.

At limpiezas técnicas industriales (Lti) the cleaning of tube bundle heat exchangers is undoubtedly another of our main tasks as it forms a very important part of the working system of these machines.

The world of tubular heat exchangers is very varied. It ranges from small stainless steel heat exchangers with a few dozen tubes for the food industry to large heat exchangers, such as steam generators in the nuclear industry, which can have more than 10,000 tubes per plate.

What is a tubular heat exchanger and what are its advantages and disadvantages?

What kind of applications is it used for?

How does a shell and tube heat exchanger work?

The shell and tube heat exchanger is a type of shell and tube heat exchanger. It is a device widely used in industry, the main purpose of which is to extract heat from a gas or liquid.

The principle of the shell and tube heat exchanger is based on a tube bundle arranged vertically or even horizontally in a shell, called a calander.

The shell and tube heat exchanger works by means of a heat exchange between two liquids. On one side there is a liquid called heating and on the other side a liquid called heat.

The liquids can be of different nature and a shell and tube heat exchanger can provide an exchange: gas/gas, liquid/liquid, liquid/gas, etc.

There are different categories of shell and tube heat exchangers on the market depending on the application the user is looking for:


In this configuration, the purpose of the heat exchanger is to provide a gas-to-liquid conversion. Therefore, as the name suggests, the heat exchanger has the function of condensing the vapour on a cold surface. Thus, the condenser is a refrigeration system that ensures heat exchange between the refrigerant and the external environment, ensuring that the liquid changes state at constant pressure and then superheats and subcools. In this way, the liquid leaves the condenser in a liquid state and not as a gas.


This time the role of the heat exchanger is to cool the liquid.
Boiler: This process is used especially in distillation plants, as the main objective is partial evaporation at the bottom of the distillation columns. A mixture of liquids or a mixture of liquids and solids is evaporated. This process is also used for heating.


Capable of working under extreme conditions, the purpose of a cooler in industry is to heat a volume of liquid or gas.


Aims to concentrate a solution by injecting energy to achieve a change of state from the liquid to the gas phase.


In this last configuration, the heat exchanger isolates the product to return it to its solid form.

Sizing a shell and tube heat exchanger
The first step in the sizing process is to choose the most suitable technology for the customer.

We consider the role the heat exchanger will play in the industry, the surface area it will occupy, the type of fluids, the pressure or temperature.

Once this has been determined, the heat capacity of the shell and tube heat exchanger has to be determined and the surface area required for the exchange has to be calculated.

Next, it is important to measure the allowable pressure drop, i.e. the energy loss of the moving fluid.

Once the design drawings have been prepared, the shell and tube heat exchanger is sent to production.

Shell and tube heat exchangers are mainly made of stainless steel, duplex, uranium, nickel alloy or incoloy.

Advantages and disadvantages of shell and tube heat exchangers.

Firstly, a shell and tube heat exchanger is an extremely robust and reliable heat exchanger. It is an industrial grade stainless steel equipment that can withstand high pressures and extreme temperatures. This heat exchanger operates with different types of media and is therefore suitable for a wide variety of applications.

Although tubular systems have many advantages, they are also bulky, so it is important to consider where they will be used in industry. Tubular heat exchangers can be tens of metres long.

In addition, there is the risk of deposits forming inside a shell and tube heat exchanger, as well as the fact that they are not easy to inspect, as they often have large tubes that need to be completely removed from the unit for cleaning.
