In order for heating or air conditioning systems to operate without any problems, ensuring the highest possible efficiency, the installation pipes must be properly insulated. Special pre-insulated pipes are used for this purpose, thanks to which the transfer of heat to users is fully effective and safe. In the following article, let's look at this issue, paying attention to the key factors. First, what a pre-insulated pipe consists of, second, how to choose its diameter to reduce heat loss, and third, finally - we will indicate pre-insulated pipes worth considering available at the Onninen wholesaler!

What does a pre-insulated pipe consist of?
Heating and cooling systems are crucial for various installations, they affect the temperature, which of course translates into our comfort. That is why pre-insulated pipes are used in modern heating networks, which are specially constructed, consisting of several basic layers.
The basis is of course the transmission pipe, which is responsible for the transmission of media, such as water, as the name suggests. It is responsible for the transport of both heat (heating agent) and cold (cooling agent). It can be made of various materials, especially steel, copper and plastics.
The next layer in the pre-insulated pipe is a casing pipe, the task of which is to separate the first layer from the insulation. This is very important, because it ensures the correct operation of the insulation while protecting the transmission pipe from mechanical damage. Such pipes are most often made of plastic, which provides them with elasticity.
The last layer of a pre-insulated pipe is a foam casing, i.e. an insulating layer that provides an effective barrier against damage and weather conditions. The material can be of different thicknesses, depending on the intended use. If the transported water has a high temperature, then of course the insulating layer must be thicker, and therefore more resistant and effectively retaining heat.
How to choose the diameter of a pre-insulated pipe?
As we already know, the pre-insulated pipe is of great importance in heating and cooling systems, so it must be properly matched with its diameter. To assess this properly, we must take into account the heat flow. The larger the pipe diameter, the smaller the flow resistance, which can affect the system's efficiency. So, to be sure of effective heat transfer, let's go for a larger diameter.
The 2x50 pre-insulated pipe is particularly effective here. Another important factor is the amount of the transported medium. If the system requires greater throughput, it is better to choose a larger diameter pipe - the 2x50 pipe mentioned above, although the 2x40 pre-insulated pipe works just as well here.
It is also necessary to take into account the route that the pipe must travel, because the longer this section, the greater the heat losses generated. A larger diameter pipe can therefore minimize these losses. At the same time, it is worth remembering that the pre-insulated pipe system is very rich, which is why other pipe diameters are available, which work well in many different tasks, for example a 2x32 pre-insulated pipe or a 2x25 pre-insulated pipe .
