The diameters of polypropylene pipes, the table of which is presented in the article, can be completely different, this determines the purpose of the products. This parameter can be considered the most common and main.
The dependence of the use of pipes on their diameter
In order to decide which pipes you need, you need to determine for what purposes they will be used. The most common pipes, the diameter of which can be equal to 90, 63, 50, as well as 25 mm. They are actively used in the arrangement of water supply systems in residential buildings. The outer diameter of the polypropylene pipes will be larger by the wall thickness relative to the inside. If it is necessary to transport chemicals, products with a diameter of 63 mm are used.
As for significant diameters (ranging from 100 to 160 mm), they are used in production. Such products are very durable, they are easy to install due to their light weight and non-susceptibility to damage.
Types of pipes
The diameters of polypropylene pipes, the table of which will help to make the right choice at the time of purchase, can be completely different. But it is important to pay attention not only to this parameter, but also to the marking, which indicates the purpose of the product. So, if you saw the abbreviation PPH, then you can use such pipes to equip ventilation systems, their inner diameter can be 300 mm. They are actively used for water supply networks, but they should not be exposed to high temperatures.
But polypropylene pipes for heating marked PPR may be subject to aggressive influences. This is due to the high quality of the base material.
What is important to know about pipe diameters?
If necessary, to supply heating systems for public buildings, pipes of significant diameters are used. This indicator can reach values of 200 mm and even more. Such products become part of the heating systems of large shopping centers, hospitals, public baths, as well as hotels.
If you are a private consumer, then, most likely, to equip your home with a heating system, you will have to purchase pipes Ø20-32 mm. They have significant bandwidth, in addition, they can be given any bend.
Polypropylene pipes for heating with a diameter of 20 mm are actively used in the installation of hot water systems, whereas if there is a need to install a riser, it is recommended to purchase pipes Ø25 mm.
When laying the underfloor heating system, Ø16 mm products should be used.
The effect of pipe diameter on system efficiency
The system will be effective if the pipeline design was done correctly. Thus, the planning stage should be accompanied by the determination of heat loss. Do not assume that by increasing the cross section, it will be possible to increase the efficiency of the system. If the diameter is unnecessarily increased, then the pressure will decrease significantly, but there will be no heating at all in the living space.
Before starting to design a heating system, each owner of a private house thinks about the question of what the diameters of polypropylene pipes should be. The table in the article will allow you to correctly determine this value. It should also be taken into account which method is used when supplying the coolant. If the house is connected to the main highway, then the determination of the parameters of the pipes must be carried out according to the same principle that is used in the case of an ordinary apartment. Whereas if the building has an autonomous heating system, then the mentioned parameter will depend on the material in the pipe base. So, if the network works due to natural circulation, then products of one diameter should be used, but if there is a pump in the system, you will need another.
What diameter to use for the heating system?
The diameters of polypropylene pipes, the table of which ultimately makes the choice, is an important parameter. In order to select it, you can use the recommendations below. Experts advise using the smallest diameter when installing a forced-type heating system. There is an explanation for this, which is primarily expressed in the fact that with a small diameter of the pipes there is no need to heat an impressive amount of water. In this case, it is possible to save not only a temporary resource, but also an energy one. In addition, polypropylene pipes of large diameters are much more difficult to lay.
But do not neglect the recommendations and calculations that indicate the need to acquire one or another diameter. If you use a pipe with a diameter not so large as required, you can get a system that works too noisy and does not differ in proper efficiency. It must be taken into account that the value that varies between 0.3-0.7 m / s is the optimal speed for transporting water in the system. That is why it is recommended to take into account precisely this value.
Diameter determination
In order to determine the inner diameter of polypropylene pipes, you can take as the main type calculation. In this case, a room with an area of 20 m 2 is used . Initially, it is necessary to calculate the amount of thermal power for heating the premises in the living space of the house. For 10 m 2, 1 kW is required. This is true if we assume that the walls are thermally insulated, and the ceiling height does not exceed 3 m.
In this example, the area is twice as large, this indicates that it will take about 2 kW. But 20% for the reserve has to be added to this value, which will make it possible to obtain 2.4 kW. According to standards, in order to heat the described room at a given power, it is necessary to use a pipe whose diameter is 8 mm. As a rule, in calculations the internal diameter of polypropylene pipes is used, and only the wall thickness, which is determined by the material in the basis of the products, differs from the external one.
