Polipropilenovyie beznapornyie pipes — a new stage in development of internal systems of the water drain

Many remember the novel of brothers Strugatsky «Monday begins on Saturday», formed a literary basis for a television movie "Magicians". In one of episodes the recognised magician chooses rather exotic method of movement — "filters" live and safe through sewer system. For the magician-professor fantastic NIICHAVO — business ordinary. But for simple our citizens any contact with water drain problems causes sincere trembling and a headache.

We often do not muse of those conveniences whic to us are given by technical progress while closely we will not face necessity to solve a problem of an engineering accomplishment in the apartment or in the house. Sharp sensations come to us, as a rule, suddenly: will break through a sewer strut, repair in the house will begin, and it is even more terrible — building of own country house. At this time we also start to search for answers to the numerous questions, one of which sounds so: what pipes to choose for the system of the internal water drain? Why for the water drain? Yes because pipes for water supply, heating — always as though in the attention centre, and here the water drain… My acquaintance already almost has finished house building when has recollected that has forgotten about water drain system. And meanwhile it is useful to remember that is forbidden to arrange with acting Building norms and rules waterpipe input in the house without the water drain.

By right it is possible to consider as deserved "veterans" of the internal water drain pig-iron pipes. Judge for yourself, these pipes have received a life in 1465 and to this day, looking in an assembly case, we see a black pig-iron sewer strut habitual to the Russian eye. Unconditionally, pig-iron pipes have the advantages: durability, durability, pozharobezopasnost. But defects which push out pig-iron pipes on a market roadside are essential also: the big weight, labour-consuming installation, the high hydraulic resistance caused by a natural roughness of pipes, zarastanie pipes corrosion and other adjournment that leads to narrowing of section through passage.

In 1935 in Germany there were first plastic pipes. Industrial production and wide application of plastic pipes in Europe, Japan and the USA has begun in the early fifties. These pipes have fast found popularity. Their small weight, convenience of installation (speed has increased in 3-4 times), reliability and durability, not susceptibility of corrosion, a choice quality of an internal surface and an aesthetic kind have liked both to builders, and consumers. By the way, in the USSR and in Russia introduction of plastic pipes has begun with intrahouse systems of the water drain and until recently it there was a unique system of the engineering equipment where use of plastic pipes has received introduction in mass building while to the system of systems of water supply and heating still basically apply steel pipes.

Substitute of sewer pig-iron pipes at the first stage of a steel of a pipe from polyvinylchloride (PVC). Pipes and connecting details are processing products neplastifitsirovannogo PVC, i.e. do not contain some the softeners which availability, facilitating processing, reduce prochnostnyie properties and temperature constancy of items.

For PVC of pipes chemical firmness and low factor of a roughness are characteristic high prochnostnyie characteristics. From PVC it is much easier than a pipe (in 7,5 times), than pig-iron pipes. Important there was also that fact, that the "know-how" of pipes from PVC is well familiar to domestic manufacturers that has allowed to reanimate a part of the Russian industrial enterprises specialising earlier on issue of items from plastic.

Occurrence beznapornyih polipropilenovyih pipes became a new stage in development of plastic pipes for internal systems of the water drain.

Polipropilenovyie pipes korrozionnostoykie, are stable against excited environments, are reliable and durable, ecologically safe and do not render negative influence on health of the person. They are fast mounted, and the durability makes them 50 years.

One of advantages polipropilenovyih pipes is their thermal stability. Now in many apartments are established washing and dishwashers from which the high-temperature drain (to 90°S) is taken away. Polipropilenovyie pipes allow to carry out transportation of sewage with temperature to 95°S, we will admit short-term dump of drains with temperature 100°S, while as much as possible admissible temperature for pipes from PVC — only 60°S.

Other difference polipropilenovyih pipes are smaller thickness of walls in comparison with pipes from PVC. So, for pipes in diameter of 40 and 50 mm the thickness of a wall makes 1,8 mm, and for pipes in diameter of 110 mm — 2,7 mm, against 3,2 mm at pipes of PVC irrespective of diameter. Necessary mechanical rigidity is thus saved. As result — reduction of a lump of pipes from polypropylene in comparison with pipes from PVC.

Beznapornyie polipropilenovyie pipes have the raised firmness to all chemicals household and to the majority of industrial drains.

At last they are distinguished by lower cost in comparison with pipes from PVC.

As is known, demand gives rise to offers. Now in the Russian market beznapornyie pipes and shaped parts from polypropylene are presented by known import manufacturers “Ostendorf” (Germany), “Martoni”, “Redi” (Italy) and domestic: NPO «Stroypolimer» and “Sinikon”. Outwardly all these pipes, apparently, a little than differ from each other. However at close examination of technical parametres and designs, it is possible to reveal some distinctions, and advantage, as a rule, appears on the party of leading import manufacturers.

Most a weak spot of pipelines is their connection. For consolidation of bell-shaped connections rubber sealing rings are used. Such kind of connection is rather simple and does not take away a lot of time. Quality of connection defines reliability of work of all system, from here at that significance which give to a design and quality of an applied rubber ring. All manufacturers complete the pipes and shaped parts from polypropylene with rubber sealing rings identical on a design. However, according to experts of Joint-Stock Company "Santehkomplekt", sealing two-petal rings with the plastic adjusting ring built in in them which is is stable against internal pressure are most perspective and supplies the maximum density of connection.

Thanks to a reliable design of a sealing ring, installation and dismantle of pipeline systems is considerably facilitated.

At installation the sealing ring is not bent and not turned out outside. Design elements incorporate easily and fast, and connection remains tight during all period of operation.

Such sealing rings, in particular, complete pipes and shaped parts of production companies "Ostendorf" (Germany).

Today it is possible to ascertain, that the scope of plastic pipes in mass construction engineering building extends. Moscow house-building combine DSK-2 began to apply to a lining of house networks of mines-packages in which for the water drain are used beznapornyie polipropilenovyie pipes, and for networks of cold and hot water supply - pressure head polipropilenovyie pipes. Such technical decision approaches our building to the European level where for drainage systems are mainly used polipropilenovyie pipes.

If you yet do not know where to purchase polipropilenovyie pipes for water drain networks we wish to answer a sacramental question: where and how much?

In the adjusted price table on beznapornyie polipropilenovyie pipes in the Moscow market. A choice for you.

Reasonable prices in a combination to a choice quality allow to consider application polipropilenovyih pipes in construction engineering building by rather perspective direction.

The XX-th century has finished the existence as "iron". The XXI-st century which has received in last century the name of "a century of polymeric materials», already in the most beginning finds to that all new acknowledgement. Source: «the Building expert» #10
