The entire civilized world for over 50 years ago, almost completely abandoned the use of steel pipes in the building and moved to modern, reliable and environmentally friendly materials and technologies. Today, this trend has become dominant. However, here we go its own way, with enviable persistence continuing to build even the “elite” housing, using outdated steel pipes, often upryatyvaya them for gypsum plasterboard. Our commitment to tradition is particularly amazing is because since 1996 the country’s existing legal framework, mandating the need for all internal engineering systems under construction and reconstruction of objects is modern PEX and not steel pipelines.
Modern house and rusty pipes in the household and drinking water pipeline – incompatible concepts. By now it is simply impossible to draw any technical or economic, or any other reasonable basis. In fact, even if the start of the traditional criteria for the builders – the size of one-time initial cost of engineering systems, it turns out that the mass construction unit costs, such as a cold water supply system, made of the most modern PEX piping shall not exceed one percent of cost of 1 square. m of living space. At the hot water system, these costs will be only slightly higher. There is no doubt that if all our “interest holders or other consumers of construction services had any real knowledge about these figures, they are two arms would have voted for the modern PEX piping, and therefore for peace and comfort in their future home. But, unfortunately, the current system of participatory construction participants were not fully aware and do not actually have the right to vote, but will have to continue to decide these issues, spending more money and effort to dismantle the rusty pipes and installation of modern pipeline systems. However, if based on common criteria – indicators of the potential damage that can be applied decoration, property for possible failures of engineering systems, defective, or even more so to take into account the costs of maintenance, repair and rehabilitation of steel pipelines, the latter exceeds the costs to the modern PEX pipelines in more than 10 times.
No less problems and constraints are steel pipes and using them for heating. Here, the builders have traditionally sold outdated technical solutions and wiring pipes, in which virtually eliminated installation in flats of individual heat meters. Accordingly, our residents simply deprived of the opportunity actually to save energy in your home, not only today but in the future. However, in St. Petersburg is now almost 80% of housing is being built on such outdated projects and technologies, “successfully” overcome the barriers of various inspections and commissions.
