Polypropylene pipes for cold water supply and hot water supply: manufacturer, diameters, GOST
An excellent replacement for steel pipes areproducts made of polymer material. In particular, this applies to polypropylene pipes intended 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 entire operation.
Why choose polypropylene
Such pipes are able to undergo pressure,which is considered normal for the backbone network, as well as a temperature reaching 95 degrees. In this case, a constant flow can be maintained. Also, similar products undergo exposure to 110 degrees with short-term temperature fluctuations. If you decide to use polypropylene pipes for cold water supply, you can count on the fact that when freezing the material will remain unscathed, which is related to the property to expand along with the frozen liquid. After thawing, the products return to their original position. Water pipes of this kind are also used for water supply, which is heated up to significant temperatures coming from the boiler or double-circuit boilers.
Varieties of polypropylene pipes
When choosing polypropylene products, you canprefer one of three varieties. The abbreviation PN10 indicates that in front of you are polypropylene pipes for cold water supply. If you find products marked PN20, then consider that use of such polypropylene pipes for cold water and hot recommended by specialists.
The above varieties havethe ability to increase the initial linear dimensions, if the material is exposed to an elevated temperature. For this reason, installation work using such products should be carried out by the method of installing different sliding supports and compensators. If you are looking for polypropylene pipes for cold water supply, you can prefer reinforced products, which are also used in heating systems. It is necessary to take into account their peculiarity, which consists in a less impressive possibility of elongation when exposed to a temperature of 60 degrees. In this case, the comparison is carried out with the mentioned quality, which is characteristic of the similar products presented above.
Diameter of polypropylene pipes
If you decide to use polypropylenepipes for cold water supply, the domestic water supply system assumes a choice of diameters, which have received the widest distribution in this area. This figure is 20, 25 and 32 millimeters. In the process of selection, it is necessary to take into account the diameter of the soldering iron tips that are available, as well as what will be used in the work. There are diameters 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 attachments. Specialists recommend starting with the purchase of a soldering iron, and only after proceeding with the selection of a suitable diameter for water or heating pipes.
Quality in accordance with GOST 52134-2003
Polypropylene pipes for coldwater supply, the diameters of which are discussed above, are produced in accordance with GOST. Among the main characteristics of these products can be allocated a long shelf life. However, this condition is met only if transportation, storage and installation have been carried out according to all the rules.
Thus, such products are capable ofto serve for half a century. This applies to hot water supply systems, whereas pipes transporting cold water can last for a hundred years. The short-term increase in temperature and pressure, however, has almost no effect on the shelf-life of products.
If you choose polypropylene pipes forcold water supply, the diameter of which was specified above, then you can be sure that materials in contact with water are made in full compliance with state standards. This indicates that the liquid reaches the consumer environmentally friendly, without foreign odors, impurities and harmful substances. The internal surface is not a favorable environment for the formation of deposits and corrosion. As a result, the inner diameter does not decrease during operation.
Choose such products also for the reason thatthey are equipped with excellent sound-absorbing characteristics. This feature is relevant, because when transporting water and coolant there are noises. Polypropylene is able to withstand the pressure and temperature differences perfectly. Condensation does not appear on the pipes, the material in the base has a low thermal conductivity. Polypropylene pipes for cold water supply, GOST of which are mentioned in the article, have insignificant weight, therefore they are easy to transport, load and unload.
Installation work can be done withoutattraction of additional construction equipment, while only two people will be enough. Installation work is carried out in the shortest possible time, if you compare with metal analogues.
Choice of polypropylene pipe manufacturer
If you decide to choose polypropylene pipes forcold and hot water supply, the manufacturer must be taken into account. Wefatherm Well, for example, it is a system of polypropylene products that are manufactured at the German factory. The German manufacturer supplies polypropylene products to the market, which have a smooth internal surface, which ensures minimal pressure losses.
Thanks to a wide range of fittings forYou can combine pipes of this manufacturer with other systems. The welded joint is sealed, and also requires a minimum amount of time for processing and subsequent cooling.
Alternative German manufacturer "Aquatherm GmbH"
If you decide to purchase polypropylene pipesfor cold / hot water supply, then you can choose the products of the above manufacturer. This company is the leader in the manufacture of products from polymer materials. Such pipes are used in a wide range of temperatures, for example, if necessary for the installation of a warm floor, heat supply, installation of air conditioning, water supply and fire extinguishing.
Another company called Faser producespipes, the diameters of which vary from 20 to 250 millimeters. They are reinforced with fiberglass and are used in systems where the temperature reaches 95 degrees. On the market of the relevant materials, one can meet pipes manufactured by Stabi. In the production process, they are reinforced with perforated aluminum, and their diameter is from 16 to 110 millimeters.
