Effective transmission of the heating medium: Pre-insulated pipe

Added: Tuesday, 4/9/2024


In order for heating and air conditioning systems to operate without any problems and ensure the highest possible efficiency, installation pipes must be properly insulated. Special pre-insulated pipes are used for this purpose, thanks to which heat transfer to users is fully effective and safe. In the following article, let's take a closer look at this issue, focusing on key factors. Firstly, what does a pre-insulated pipe consist of, secondly, how to choose its diameter to reduce heat losses, thirdly, and finally - we will point out the noteworthy pre-insulated pipes available in the Onninen wholesaler!

What does a pre-insulated pipe consist of?

Heating and cooling systems are crucial for various installations, they influence the temperature, which of course translates into our comfort. This is why modern heating networks use pre-insulated pipes, which are specially constructed and consist of several basic layers.

The basis is, of course, the transmission pipe, responsible for the transmission of media, such as water, as the name suggests. It is responsible for both the transport of heat (heating medium) and cold (cooling medium). It can be made of various materials, especially steel, copper and plastics.

This is very important because it ensures proper operation of the insulation while protecting the transmission pipe against mechanical damage. These types of pipes are most often made of plastic, which makes them flexible.

The last layer of the pre-insulated pipe is the foam lagging, i.e. an insulating layer that constitutes an effective barrier, protecting against damage and weather conditions. The material may have different thickness, depending on the purpose. If the transported water is at a high temperature, the insulating layer must, of course, be thicker, making it more resistant and effectively retaining heat.

How to choose the diameter of a pre-insulated pipe?

As we already know, a pre-insulated pipe is of great importance in heating and cooling systems, so it must be properly matched taking into account its diameter. To assess this properly, we must take into account the heat flow. The larger the pipe diameter, the lower the flow resistance, which may affect the system's performance. Therefore, to ensure effective heat transfer, let's choose a larger diameter.

The 2x50 pre-insulated pipe works especially well here. Another important factor is the amount of transported medium. If the system requires greater capacity, it is better to choose a pipe with a larger diameter - the 2x50 diameter pipe mentioned above, although a 2x40 pre-insulated pipe works equally well here.

You should also take into account the route that the pipe must cover, because the longer this section, the greater the heat loss. A larger diameter pipe can therefore minimize these losses. It is also worth remembering that the pre-insulated pipe system is very rich, which is why other pipe diameters are available, suitable for many different tasks, for example a 2x32 pre-insulated pipe or a 2x25 pre-insulated pipe .
