Among the large number of varieties of pipes, polyethylene are distinguished, which are suitable for the installation of sewage, water supply and gas communications. After a relatively recent appearance on the market, they managed to gain sympathy and trust due to their qualities that distinguish them from iron and other types. The secret of the popularity of PNP pipes lies in the raw materials, which is used for production. The fact is that they have the ability to expand, which is especially valuable in conditions of local climate with harsh winters – the time of the year when accidents in water supply systems and systems of water disposal occur quite often. The main cause of the winter accident is the rupture of pipes that could not withstand the expansion of the liquid in the cold air. Polyethylene systems can withstand such a test subject to proper installation – they narrow during the thaw and expand in the cold. In addition, they have another undeniable advantage – a low price compared to other varieties. In installation, they do not represent any complexity and after installation they have a neat appearance. But a positive end result requires professional skills and knowledge of the installation specialist.
At the obviousness of all the positive aspects of the city municipality, it is in no hurry to use PNP pipes to replace the old failed systems. Complete reinstallation of urban water supply and sewage systems will avoid in the future expenses to eliminate emergency situations, which sometimes need to be connected by a considerable number of special equipment. As a result of a system malfunction, not only individual entrances and houses can remain without water, but even entire quarters. Water leakage is an unpleasant situation, and if we are talking about a gas pipeline, then an accident can become a threat to people’s lives and the preservation of their home. It is not uncommon in the entrances of multi -storey buildings that can be caught by the smell of gas, which penetrates through poor -quality compounds. The reason for the failure of the system of the city gas pipeline may be the end of the prescribed period of pipes, which are still used in the housing stock for half a century. They require urgent replacement in order to prevent the occurrence of further leaks and accidents. Unfortunately, in state institutions it has long been able to respond to what happened, and not look into the future and prevent troubles through the timely installation of modern types and materials.
