In countries of Eastern Europe - Hungary, the Czech Republic, Poland, Romania - even more often copper is applied to production of systems of water supply, heating and gas supply of buildings. And Russia is not an exception. Traditionally in such systems steel pipes were applied, in the early nineties began to experiment with plastic. But, in spite of the fact that the share of plastic pipes in the market is not so small (as some types and brands of plastic pipes offer the attractive prices), only pipes from copper and stainless steel can provide to the customer tranquility for many years. In recent years the tendency of full refusal of application of steel pipes (their use is forbidden in Hong Kong, Singapore, with some reservations in China) and plastic (the largest Swedish builder - the JM company - imposed the moratorium on use of plastic and me-talloplastikovy pipes in the buildings) in favor of copper was designated.
In the Russian standards copper is carried to the recommended materials for internal pipeline systems too. It is characteristic that MGSN 4.19-2005 "Temporary norms and rules of design of multipurpose high-rise buildings and buildings complexes in Moscow" demands, for example, for systems of water supply of application of metal, including copper pipes: "... 8.6. Pipelines of a water supply system of cold and hot water (vertical and horizontal) have to be provided from metal pipes (internal and external surfaces, steel with a reliable anticorrosive covering, from stainless steel, copper).8.7. Eyeliners of pipelines to a sanitary tekhni-cheskim to devices and other equipment are allowed to be made from metalloplastikovykhtrub or pipes of polymeric materials..."
