Corrugated two-layer polypropylene pipes of PP-B (PP-V) grade with a nominal diameter of 200mm to 800mm of ring stiffness SN4, SN8, SN16 are produced by the Brovary-Plastics manufacturing enterprise, according to DSTU BV.2. 5-32: 2007 and are intended for pipelines transporting wastewater in a free-flow mode that is not aggressive to the pipe material.
POLYCORR pipes application
Application area code UD, for products intended for underground laying of sewage networks without limiting the distance from buildings and structures, as well as under buildings and structures. Pipes can also be used in hydro-reclamation construction, agriculture, for environmental protection, drainage systems, as well as any type of cable protection in communication and energy systems.
Advantages of polypropylene pipes
Significant weight reduction not only in comparison with concrete, ceramic pipes, but also with PVC pipes, rigid PE (PE-HD) and monolithic pipes.
The cost of raw materials accounts for about 75% of the total pipe manufacturing costs. Due to its low specific gravity, PP corrugated wall pipes can be cheap Among all plastics sewer pipe systems.
Considering the high chemical resistance of polypropylene, the pipes are suitable not only for water supply, drainage of domestic waste water and storm water, but can also be used in production systems and chemically contaminated soil.
Unlike concrete pipes, due to smooth, even surfaces, inside the pipe there are no favorable conditions for the development of microorganisms and bacteria. Decomposition of effluent due to the action of bacteria in the absence of oxygen usually leads to the formation of a strong acidic environment, as a result of which the surface of concrete pipes corrodes. PP pipes resistant to this process
PP pipes are characterized by highundefined abrasion resistance among materials used for the manufacture of sewer pipes. This makes it possible to design channels with a steep slope, as well as to transport liquids heavily contaminated with silt and sand ..
Due to the high heat resistance of the material, the transported liquids can have a temperature of 60 ° C with a continuous flow, and also 95 ° C with a short-term flow.
PP pipes have high impact resistance, as well as at low temperatures, which is why they can be used at temperatures of -20 ° C. Other plastic pipes cannot be used at such a wide temperature range. undefined
installation of pipes
Corrugated pipes are connected by means of sockets with the use of special gaskets in the last groove of the socketless end. The pipes are completed with these gaskets. No special qualifications are required to lay the POLYCORR pipe, it is enough to instruct the workers. It is also not necessary to use special tools or any additional materials. Everything you need is supplied complete with a pipe. Design features minimize the risk of installation errors. The speed of pipeline installation is not standardized by the number of joints per shift or the length of the mounted sections. It is limited only by the speed of excavation.
