Now it seems difficult to explain, but in Soviet times, all the pipelines were to be made entirely of metal. While PEX tubing are not even mentioned in the construction norms and regulations (SNIP). Meanwhile in Europe, PVC fittings have been used successfully for several decades (even with the 30-ies). In Canada, they appeared only in the mid-90’s.
We have long believed: if the fittings – something metal. Just as, for example, everything in the Soviet era thinking that the clothes – and there are clothes, and in Western countries have long been, for example, youth clothes, clothes for older people and others back to the PVC fittings, we note that in Europe the study of polyvinyl chloride (PVC) in the operation lasted for about 30 years. Therefore, the data obtained, in which systematic analysis of the material properties for such a long period, can be extremely biased. These data suggest the usefulness of PVC fittings because of their range of benefits. And the use of such pipes can be in different sectors of the economy.
Now PVC fittings, for example, are widely used in the construction of various hydro-technical installations. These include water parks, swimming pools, fountains, etc. Active use of these fittings are related to several factors. First, it is worth noting the ease of transportation pipes. Secondly, the installation can be carried out very quickly, with construction works do not require special equipment, and workers do not need special installation skills. Third, the PVC fittings make it easy to design the most complex configuration.
If we talk about performance-pipes, then, first of all, it should be noted durability and resistance to corrosion. Due to the special chemical composition of PVC fittings piping is not exposed to acids and alkalis, certain types of gasoline, alcohol and other pipes have high resistance to bacterial attack. Inside the walls of pipelines does not appear mineral deposits.
Such pipes are used for transporting drinking water. PVC is resistant to aggressive environments. This quality is very valuable. Actively used PVC fittings, the chemical industry. The high corrosion resistance of PVC fittings used in agricultural production. In particular, they are used for the construction of irrigation systems. In animal buildings PVC fittings used for water animals.
