Today, private craftsmen and professional teams are increasingly using polypropylene pipes for heating. How to choose them, it is important to know before you make a purchase. Steel or cast-iron products are not used so often when installing engineering systems , as polypropylene displaces them.
Varieties of PP pipes for heating installation
Polypropylene pipes for arranging heating systems can be divided into several main types. Among them - reinforced with aluminum canvas. Such a reinforced polypropylene pipe has a special layer, which can be located outside or located closer to the middle or inner wall of the product. In production, solid aluminum sheets, non-continuous or completely corrugated, can be used.
Fiberglass Pipe Reinforcement
Pipe reinforcement can also be made on the basis of fiberglass. This material is located in a pipe using coextrusion technology. And they introduce it into the inner layer. Polypropylene acts as the inner and outer layers.
Composite reinforcement
Reinforced polypropylene pipe may assume a composite layer as a reinforcing layer. In this case, the reinforcing layer is distinguished not only by the presence of the composite, but also polypropylene, as well as fiberglass. This technology for the production of pipes allows you to get products that have more outstanding performance characteristics.
Characteristics of PP pipes for installation of heating systems
Polypropylene pipes for heating, the technical characteristics of which can be found in more detail in the article, are no coincidence that more traditional products are gradually being replaced from the market. This is due to the fact that they have excellent operational characteristics, which were achieved due to the multilayer walls of the products. The methodology for the production of polypropylene pipes has increased the resistance to mechanical wear. In addition, due to their outstanding qualities, they are actively used in the installation of systems through which cold and hot water is transported. Among other things, PP products are quite easy to stack, while there is no need to use heavy equipment, the rental of which increases the cost of the work. Ease of installation due to the low weight of polypropylene. The same applies to issues of transportation and subsequent unloading, which are quite simple to solve.
Tightness and resistance to influences
Polypropylene pipes for heating, the technical characteristics of which will become known to you after reading the article, are quite simple to maintain. The need for their repair does not arise during the entire period of operation guaranteed by the manufacturer. Among the positive features of polypropylene products, absolute tightness can also be distinguished. And after laying, there is no need to paint, as the surface already has increased resistance to external influences and aggressive environments. Polypropylene is also distinguished by the fact that microorganisms are not able to arise and multiply on its surface, as for the internal walls on which mineral deposits are not formed, they eliminate the need for cleaning and premature repair.
Environmentally friendly and low resistance
Have you decided to purchase polypropylene pipes for heating? How to choose them, you need to know in advance. It is important to consider that, unlike some other types of pipes, the described ones are completely environmentally friendly. This indicates that products of this kind are completely harmless and safe. They can also be used in the internal space of residential premises, because PP does not emit harmful substances into the environment, in addition, the material in the basis of such pipes does not affect the structure of water.
Professionals advise choosing polypropylene pipes for water supply also because such products are characterized by an insignificant coefficient of hydraulic resistance, and no vibrations are observed during the transportation of liquids through pipes. Polypropylene pipe is not able to be a conductor of stray currents. The material may be affected by an aggressive chemical environment, this will not act as a detrimental effect. A significant pressure of water can also affect polypropylene pipes for heating. How to choose them, it is important to know, because even such modern material with the wrong choice can simply become unusable.
Fire resistance
Another plus of such products is a rather high resistance to fire, with its direct impact, the pipes do not ignite. Liquid of significant temperature can be transported along them, while the walls do not lose their quality characteristics and do not change linear dimensions. To everything else, we can not add that PP has a low cost. And the products will serve within half a century.
Area of use of PP pipes for heating
In different areas, polypropylene pipes are used for heating. How to choose them, you need to know every consumer who plans to engage in the installation of engineering systems. Thus, PP pipes for heating can be used in boiler plants, when installing risers, for installing central heating systems, during the installation of hot and cold water supply systems. In addition, in recent years, PP has become part of underfloor heating systems.
These pipes are also widely used in the agricultural industry. In this area, the described products are used in the discharge of wastewater and soil water. It is quite convenient to use such pipes when installing irrigation and drainage systems. The industry also applies them if necessary to arrange the transportation of chemicals and compressed oxygen.
Diameters of PP pipes for heating
Polypropylene pipes for water supply and heating differ in different diameters. This parameter can be called one of the most important in the design of the pipeline. The diameter should be selected after hydrodynamic calculation. At the same time, professionals are committed to choosing the smallest pipe diameter for any section. This indicator should be determined taking into account the operating pressure, as well as the heating circuit.
The diameter of the polypropylene pipe for heating is selected based on demand. Thus, if there is a need to equip a large hospital, large sauna or hotel with an engineering system, then, as a rule, pipes with a diameter exceeding 200 mm are used. Only through such products is it possible to equip a system that will have to function correctly and justify the needs of a large number of people.
If there is a need to mount heating in a private house from polypropylene pipes, it is recommended to use products of not such an impressive diameter. This parameter should vary under the described conditions from 20 to 32 mm. PP pipes of this diameter will simply be enough to lay on their own, giving them the desired bend. While the bandwidth they have will be sufficient for a private developer.
If it is necessary to equip a hot water supply system, reinforced polypropylene pipes for heating should be used, the diameter of which is 20 mm. What about risers? It is advisable to use products with a diameter equivalent to 25 mm. The central heating system is not complete without pipes 25 mm in diameter. When installing an autonomous heating system, it is necessary to use products with different diameters.
Planning to equip a warm floor system? Then you must purchase 16 mm pipes across, but no more. Despite the existing recommendations, it is necessary to choose the diameter of the pipes for the installation of the heating system, taking into account the individual characteristics of a particular heating branch. If you decide to purchase a PP pipe, then for 4 m you will have to pay 80 rubles. In this case, the product will have a diameter equal to 20 mm. But a 40 mm pipe across will cost 138 rubles. The length remains the same. A product with a diameter of 63 mm has a price equal to 345 rubles for 4 m. With a diameter of 90 mm, the buyer will pay 810 rubles.
