Polypropylene pipes for hot water - choose the best option

In the process of construction or major repairs of their homes, almost every person has to choose pipes to equip a high-strength and reliable communication system. The modern market of construction materials is simply overcrowded with various options, for example, a polypropylene pipe (the price of which, it is worth noting, is quite acceptable), metal-plastic, steel products and much more. But which of them should be preferred? This issue has recently become the most urgent.

Previously, for hot water supply , only metal pipes were used, which had to be repaired almost every year. However, thanks to new technologies, it became possible to use higher-quality materials. They have a longer service life and are considered as economical as they do not require painting and special care. One of the most popular options at present are polypropylene pipes for hot water. This type is ideal for any room, with no special requirements for temperature and humidity levels. Polypropylene pipes can be installed in residential buildings, industrial buildings (factories, factories), in boiler rooms, and even cellars. It is because of the operational properties of this material has won great popularity in the construction of communications of a new generation.

Specifications

More recently, this material was completely unfamiliar to a wide range of consumers. However, in the shortest time, everything changed radically. Increasingly, professional builders recommend that their customers install such products. What are their advantages? In order to answer this question, it is necessary to study in detail what the polypropylene pipe is.

Technical characteristics (basic indicators):

• The heat capacity is 1.75 kJ / kg ⁰ C.
• Extension linear - 3,5 ÷ 10 ^-5 ( ^1/0 С).
• The coefficient of equivalent roughness is 0.015 mm.
• The maximum tensile strength is 35 MPa.
• Thermal conductivity - 0,15 WT / ⁰ С.
• The density is 0.989 g / m ³ .
• The pressure is 25 bar.
• The maximum stretching index is 30 MPa.
• The welding time is 4-8 seconds.

Advantages of polypropylene pipes

When purchasing polypropylene pipes, one important factor must be taken into account - the coefficient of thermal expansion. Thermal conductivity of propylene and metal is different. As is known, metal compounds are more sensitive to sharp temperature changes. For example, if hot water was fed through the pipe for a long time, and then the cold went sharply, this leads to rapid destruction. Fortunately, because of the minimal amount of metal, polypropylene pipes are not exposed to this process, which allows them to serve for a very long time and reliably.

So, let's consider the main advantages of this product:

• High strength;
• Durability, service life of more than 50 years;
• Polypropylene pipe GOST PN20 does not break even when water freezes;
• Ease of installation, with the laying of communications can handle one person;
• reliability;
• Has a high coefficient of hydraulic resistance ;
• Resistance to large temperature fluctuations, water heating can reach up to 100 degrees;
• Good flexibility;
• Not susceptible to corrosion;
• The ability to expand under the influence of high temperature.

Key points

Polypropylene pipes for hot water are connected with each other using fittings or press fittings. This allows to ensure high-quality adhesion and tightness of the joint, which can last for several decades.

An important point: the water in contact with the polypropylene pipe keeps its molecular structure unchanged, which is extremely important for people's health.

Features of the internal structure

A conventional polypropylene pipe is a three-layer structure, which ensures high strength and reliability of the entire system. Two of them are basic, and one is in between. It acts as a fixative. The inner and outer layers are made of polypropylene, and the middle layer is made of aluminum of small thickness or fiberglass.

Due to the high flexibility of materials, polypropylene pipes for hot water are very easy to install, and you can change the direction of heating systems or water pipes. The inner layer has a smooth surface, which does not create any obstacles for water circulation.

Cost

Such pipes are often supplied with long bays, so that during the installation, joints and joints are practically not formed. Modern communication products are universal, so they can be used for both external and internal systems. Polypropylene pipe (price - from 20 rubles per 1 meter) is inexpensive in itself, however, during installation, it is necessary to take into account the cost of all connecting elements, as well as the work of the master. In any case, the long life of such systems will allow further saving on maintenance.

Undoubtedly, each person tries to create in his house the maximum level of comfort and comfort, so he is looking for the most modern and advanced materials for housing. Since the water pipeline is one of the most important components of comfort, more attention is paid to this particular engineering system. Therefore, it is recommended to install polypropylene pipes for hot water. And inexpensive, and durable.
