Diameters of polypropylene pipes: table. Polypropylene pipes for heating

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 most important.

Dependence of the use of pipes on their diameter

In order to decide which pipes you need, you need to determine what goals they will be used for. The most common pipes, the diameter of which can be equal to 90, 63, 50, and also 25 mm. They are actively used in the arrangement of water supply systems in buildings of residential type. The outer diameter of polypropylene pipes will be larger by the wall thickness in relation to the inner one. If it is necessary to transport chemicals, products with a diameter of 63 mm are used.

With regard to significant diameters (ranging from 100 to 160 mm), they are used in production. Such products are very durable, they are easy to assemble due to their low weight and non-damage.

Types of pipes

Diameters of polypropylene pipes, the table of which will help to make the right choice at the time of the 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 the ventilation systems, their internal diameter can be equal to 300 mm. They are actively used for water supply networks, but do not expose them to high temperatures.

But polypropylene pipes for heating with PPR marking can be subject to aggressive influences. This is due to the high quality of the material in the base.

What is important to know about pipe diameters?

If necessary, large diameter pipes are used for the heating system of public buildings . This figure can reach a value of 200 mm and even more. Such products become part of the heating systems of large shopping centers, hospitals, public baths, and hotels.

If you are a private customer, then, most likely, for the arrangement of your home heating system will have to buy pipes Ø20-32 mm. They have considerable 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 buy Ø25 mm pipes.

When installing the underfloor heating system, use Ø16 mm products.

Effect of pipe diameter on system efficiency

The system will be effective if the pipeline design has been made correctly. Thus, the planning phase should be accompanied by the definition of heat loss. Do not assume that by increasing the cross section, it will be possible to increase the efficiency of the system. If you excessively increase the diameter, the pressure will drop significantly, but there will be no heating in the residential space at all.

Before starting to design a heating system, every owner of a private house ponders the question of what the diameters of polypropylene pipes should be. The table given in the article will allow 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 road, then the definition of the parameters of the pipes must be made according to the same principle that is used in the case of a conventional apartment. Whereas if the building has an autonomous heating system, then the parameter will depend on the material at the base of the pipes. So, if the network works at the expense of natural circulation, then products of the same diameter should be used, but if there is a pump in the system, another one will be needed.

What diameter should I use for the heating system?

Diameters of polypropylene pipes, the table of which allows you to ultimately determine the choice, is an important parameter. In order to select it, you can use the following recommendations. Experts advise to use the smallest diameter when installing a forced-type heating system. This has its own explanation, 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. Thus it is possible to save not only a time resource, but also energy. In addition, large diameter polypropylene pipes are much more difficult to stack.

But do not neglect the recommendations and calculations that indicate the need to purchase a particular diameter. If you use the installation of a pipe that is not as large as required, you can get a system that works unnecessarily noisy and does not have the proper efficiency. It is necessary to take into account that the optimum speed of water transportation in the system is a value that varies within 0,3-0,7 m / s. That is why it is recommended to take this value into account.

Determination of diameter

In order to determine the internal diameter of polypropylene pipes, one can take as the main standard calculation. In this case, a room is used whose area is 20 m ² . Initially, it is necessary to calculate the volume of thermal power for heating the room in the residential space of the house. For 10 m ^2, 1 kW is required. This is true if we assume that the walls are insulated and the ceiling height does not exceed 3 m.

In the example under consideration, the area is twice as large, this indicates that it will take about 2 kW. But to this value it is necessary to add 20% for a stock, which will allow to get 2.4 kW. By standards, in order to heat the described room at a given power, it is necessary to use a pipe with a diameter of 8 mm. As a rule, the internal diameter of polypropylene pipes is used in calculations, and only the thickness of the wall, which is determined by the material at the base of the products, differs from the external one.
