An excellent replacement for steel pipes are products made of a polymeric material. This is especially true for polypropylene pipes designed for both cold and hot water supply. They are made of polypropylene "Random copolymer". With their help, it is possible to equip durable systems without thinking about the integrity of the pipeline throughout the operation.
Why choose polypropylene
Such pipes can undergo pressure, which is considered normal for the main network, as well as temperatures reaching 95 degrees. In this case, a constant flow can be maintained. Also, such products undergo exposure to 110 degrees with short-term temperature fluctuations. If you decide to use polypropylene pipes for cold water supply, then you can count on the fact that when freezing the material will remain unharmed, due to the property of expanding along with the frozen liquid. After thawing, the products return to their original position. Water pipes of this kind are also used to supply water, which is heated to significant temperatures, coming from a boiler or double-circuit boilers.
Varieties of polypropylene pipes
Choosing polypropylene products, you can choose one of three varieties. The abbreviation PN10 indicates that before you are polypropylene pipes for cold water supply. If you meet products marked PN20, then consider that the use of such polypropylene pipes for cold water and hot is recommended by specialists.
The above species have the ability to increase the initial linear dimensions if the material is affected by elevated temperature. For this reason, installation work using such products should be carried out by the method of different sliding supports and compensators. If you are looking for polypropylene pipes for cold water supply, you may prefer reinforced products, which are also used in heating systems. It is worth considering their feature, which consists in a less impressive possibility of elongation when exposed to a temperature of 60 degrees. In this case, a comparison is made with the mentioned quality, characteristic of similar products presented above.
Diameter of polypropylene pipes
If you decide to use polypropylene pipes for cold water supply, then home water supply involves the choice of diameters that are most widely used in this area. These are indicators in 20, 25 and 32 millimeters. In the selection process, it is necessary to take into account the diameter of the soldering iron nozzles, which are available, as well as what will be used during the work. Diameters range from 40 to 90 millimeters, and the most popular indicator for a sewer pipe is 110 millimeters. However, standard-type soldering irons may not have such nozzles. Experts recommend starting with the purchase of a soldering iron, and only after proceeding with the selection of the appropriate diameter of water or heating pipes.
Quality in accordance with GOST 52134-2003
Polypropylene pipes for cold water supply, the diameters of which are discussed above, are produced in accordance with GOST. Among the main characteristics of these products can be identified long shelf life. However, this condition is only observed if transportation, storage and installation were carried out in accordance with all the rules.
Thus, such products can last for half a century. This applies to hot water systems, while the pipes that transport cold water can last a hundred years. A short-term increase in temperature and pressure in this case is almost not able to affect the shelf life of products.
If you choose polypropylene pipes for cold water supply, the diameter of which was indicated above, you can be sure that the materials in contact with water are made in full accordance with state standards. This indicates that the liquid reaches the consumer environmentally friendly, without extraneous odors, impurities and harmful substances. The inner surface is not a favorable environment for deposits and corrosion. As a result, the inner diameter does not decrease during operation.
Sound absorption
Such products are also chosen for the reason that they are equipped with excellent sound-absorbing characteristics. This feature is relevant, because when transporting water and coolant, noise occurs. Polypropylene is able to withstand pressure and temperature extremes. No condensation appears on the pipes, the base material has a low thermal conductivity. Polypropylene pipes for cold water supply, the GOST of which is mentioned in the article, are of light weight, so they are easy to transport, load and unload.
Installation work can be carried out without involving additional construction equipment, and only two people will be enough. Installation works are carried out in the shortest possible time, if we compare with metal analogues.
Choosing a manufacturer of polypropylene pipes
If you decide to choose polypropylene pipes for cold and hot water supply, the manufacturer should always be considered. Wefatherm Well, for example, is a system of polypropylene products that are produced at a German factory. The German manufacturer supplies polypropylene products to the market, which have a smooth inner surface that provides minimal pressure loss.
Thanks to a wide range of fittings for the connection, you can combine pipes from this manufacturer with other systems. The welded joint is airtight and also requires a minimum amount of time for processing and subsequent cooling.
Alternative German manufacturer "Aquatherm GmbH"
If you decide to purchase polypropylene pipes for cold / hot water supply, then you can choose the products of the aforementioned manufacturer. This company is a leader in the manufacture of products from polymeric materials. Such pipes are used in a wide temperature range, for example, when it is necessary to equip a warm floor, heat supply, install air conditioning systems, water supply and fire extinguishing.
Alternative companies
Another company called Faser produces pipes with diameters ranging from 20 to 250 millimeters. They are reinforced with fiberglass and are used in systems where the temperature reaches 95 degrees. Stabi pipes can be found on the market for relevant materials. In the production process, they are reinforced with perforated aluminum, and their diameter is from 16 to 110 millimeters.
