Advertising as we know, the motor trade. And it is the power of this engine often depends the successful implementation of products. But we must not forget that too much press on the gas pedal leads to sad consequences.
However, the question as it might seem, would not the practice of advertising or driving lessons, but the sad examples of unprofessional or even worse, intentional approach to bringing the tubing of polymer materials to the consumer.
The very first thing that interested buyer – the possible scope of tubing and the main operating parameters. Given that PEX tubing have been widely used in Russia for domestic water and heating systems only in the last four years, yet for some of these products are a novelty, so the temptation to offer a consumer plastic tubing, which “might” work everywhere, even in systems heating with superheated steam, alas, is too large.
So, after visiting the exhibition or in the office of a company, you get a booklet (or hot assurances), in which black and white – working temperature “our tubing” (mostly Metal) +95 ° C, pressure 0.1 MPa. Lifetime while 50 years! But it’s not all. In order to finally slay the client, followed by a modest posPEX Universeript: “possibly short-term increase in temperature up to +110 ° C” (the record of such a “possible” increase, as recorded by the author, +135 ° C). Needless to say, such a fantastic settings have on inexperienced consumers magical effect. As a result of PEX tubing installed in the heating systems, where the coolant used superheated steam. Taking place due to the amateurish approach of the accident completely wrongly formed a negative attitude to PEX tubing. It is doubly a pity that in Russia the same “rake” is already advancing in the 60′s, when polymer materials and the experience of their practical application were a novelty.
At the same time, industrialized countries have relied on improving the regulatory framework governing the use of PEX tubing. As a result – today more than 80% of tubinglines are made of polymer materials. The low accident rate and a high degree of reliability and durability of plastics engineering services provided by, firstly, clear by following the requirements specified in the regulations and, secondly, by a qualified installation of tubinglines, which must be performed by professionals who have special training and have the corresponding license for such work.
