When choosing new pipes for hot water supply, first of all, you need to determine the material from which they are made, since the properties of the pipe directly depend on it.
Let’s start with the usual metal pipes. They have been known for a long time, but today are recognized as outdated and unprofitable. The service life of such pipes does not exceed 20-30 years, which is considered not a very long period, they are subject to corrosion in the places of joints of the plots, water cools very quickly, moreover, leaks are guaranteed. The inner surface of the metal pipes is rough, which contributes to the formation of scale and the deposition of substances dissolved in water. This significantly increases the hydraulic resistance of the system and leads to an early failure. Well, finally, metal pipes perfectly conduct sound and vibrations, which makes them buzz, and this really prevents the residents of the house.
More modern and optimal in terms of price and quality – metal -plastic pipes. These pipes can withstand tremendous pressure, are not afraid of hydraulic strokes and can last 30-50 years. They are not subject to corrosion, do not need special maintenance, and their heat transfer coefficient is very low, which can significantly reduce heat losses compared to metal predecessors.
Not so long ago there were pipes made of stitched polyethylene. They are not very common, very expensive, but have a number of advantages. For example, one of these advantages is increased flexibility, thanks to which installation without joints of areas up to several hundred meters long has become possible. The minimum of joints reliably protects against leaks.
Also, when choosing pipes for DHW, you need to consider their diameter. At the same time, do not forget about the length of the system, the hydraulic resistance of the pipe and the intended flow of water. The exact data will be reported only by the specialist, and as for the riser and wiring on the floors, they use pipes with a diameter of ¾ – 1 inch (19-25 mm) and a little large 0.5 inch (about 12.7 mm).
If your pipeline system requires reinforcement, you can contact the company “Enjuko”, which is engaged in the supply of high -quality AVK brand to the Russian market. In the assortment of products you will find a flange adapter AVK Supa Plus, connectors, adapters, couplings, valves, shutters, return valves and much more. Enjuko participated in the reconstructions of engineering systems at many Russian enterprises and near abroad, and won a good reputation among many large firms of different branches of activity.
