The first thing you see, to investigate this issue – sites of firms that produce and install systems from a variety of plastic and metal pipes with a description of (advertising) of their products. Nobody advertises and not agitating for steel pipes. Do not agitate and does not endorse any reason as steel pipes – the bread industry and construction! You advertise anywhere bread seen? That's right! Bread all take and no advertising. The main advantages plastic pipes in that they do not rust, have smooth inner walls that are overgrown with less sediment and debris, easy for installation and convenient for transportation. You look out there, how they are better than anyone no longer necessary, conventional steel and, by virtue of inadequate expense, copper pipes. Really! On the one hand we hear about accidents in the heating mains, flashed on television footage rotting underground of heat – this problem is nationwide … read about the disadvantages of steel pipes on sites that promote a variety of plastics. On the other hand in the papers about the trade wars that break out on the black market iron and steel, the trade bans and restrictions on supply of steel pipes in different regions, about the war for the metal market.
Statistics say that more than 6 million tons of steel pipes, only one of the Russian Federation. Unwittingly the question arises: who else needed so bad and old materials – steel pipe? Who else uses them, when there are new, so good – a progressive and advanced materials, like plastic, and all of it is done in including pipes. And why are interested in Germany the amount of plastic pipe does not exceed 10% of the total market. One of the main arguments for manufacturers of plastic pipes is ostensibly a long life, which on their own estimates, at least 50 years, which is equivalent to the most durable – copper pipes, while the life of steel pipes according to generally accepted standards of no more than 20 years.
