In the online shop sells polypropylene pipes and fittings with diameters of 50 and 110 mm for the sewerage systems of buildings. Pipes and fittings at one end smooth and the other have funnel with a rubber O-ring. When installing sewage systems smooth the end of one tube (fittings) is inserted into the socket and the other is sealed with a rubber ring. Ring – lobe, so the installation and dismantling of connections require much less effort than with a ring of circular cross section.
In the process of mounting a smooth butt end of a pipe a few not brought all the way to funnel the other, so that a gap is formed between them, which compensates for the linear extension of the pipeline, resulting in transportation via pipeline of hot water. Required number of such compounds at each site is determined by calculation.
The smooth inner surface of polypropylene tubes, first, reduces the likelihood of them dirty, and secondly – can run them with fewer, than in the case of cast iron sewer pipes, slopes.
P. 17.9 SNIP 2.04.01-85 * “Domestic water supply and sewerage of buildings” regulates the use of plastic pipes in sewage systems, including in terms of fire protection requirements.
In the sewerage systems of buildings polypropylene pipes and fittings are recommended for transporting waste liquids with constant flows of 80 ° C, while the polyethylene and polyvinyl chloride – a temperature of 60 ° C. 4.1.1 SP 40-102-2000 (domestic sewage systems of buildings should be mounted out of sewer pipes, designed for transportation of waste water at a constant temperature above 75 ° C) makes polypropylene tubes in preference to pipes of other materials.
Pipes for sewage systems are manufactured according to specifications ASTM 4926-005-41989945-97 “Tubes and pipes of polypropylene for drainage, fittings, in accordance with ASTM 4926-010-419899-45″ Parts molded from polypropylene for sewage pipe ” . All products have certificates of conformity.
