PVC pipes for interior sewage are obtained through extrusion, in accordance with the provisions of the SF77 standard.
The pipes are made through co-extrusion, in accordance with the SR EN13476-3:2007 standard, resulting a pipe with a smooth light colour interior wall that facilities video inspection, with an extremely reduced roughness and a profiled type exterior wall.
The system is made out of PP corrugated pipes and fittings included in the SN8 (8kN/square meter) stiffness class. In what concerns the size, the pipes are differentiated based on their diameter into:
1. DN/OD pipes – the diameter indicated in the exterior diameter of the pipe.
2. DN/ID pipes – the diameter indicated is the interior diameter of the pipe.
Each of these ranges has its own range of fittings.
The diameter range varies between 160 mm and 1000 mm.
The pipe joining is done using O-ring gaskets from synthetic rubber (EPDM, SBR, NBR), ensuring the system sealing.
The profiled exterior wall provides resistance to external charges, being characterized by a very good resistance. The profiled structure of the exterior wall presents a number of major advantages: it is thinner than a smooth wall for the same pipe resistance which leads to a lower specific weight of the
pipes.
In order to resist to the devastating effect of solar radiation, the exterior walls of corrugates pipes are made out of materials that were stabilized against ultraviolet radiation.
PE and PP pipes are part of flexible pipes category. This feature gives plastic pipes outstanding mechanical strength, which can transfer in their around soil much of the loads exerted on them. In case of overload, PE and PP pipes, similar with PVC-U pipes, react in a reversible deformation which has no effect on their functionality, if installation conditions
are respected.
Both pipes and fittings in PE and PP have high chemical resistance to most aqueous solutions, the aggressive action of materials in the soil, salts and caustics or acidic aqueous solutions. Thus, pipes and fittings in PE and PP may be used for the transport of aqueous acidic or basic solutions,
minerals, etc. with pH between 2 and 12.
PE pipe and fittings system can withstand at temperatures up to 50° C for short periods up to 75° C. In the case of PP systems, working temperatures are higher due to better characteristics of propylene from this point of
view, so it can continue operating at working temperatures of 60° C and max. 95° – 100°C on short term.
The outstanding characteristics of the hydraulic system of pipes and fittings in PP are determined by the ability to produce interior walls with an extremely low roughness(between 0.0011mm and 0.0015mm). System also features a high abrasion resistance, much higher compared to other systems made of plastics being a particularly suitable system for channeling rainwater containing numerous grains of sand or gravel.
Piping system inside is manufactured in a bright color that provides a very good visibility to facilitate inspection with video cameras.
The lightweight of PE and PP pipes and fittings system components ensures extremely high manoeuvrability in terms of transport, storage, handling and installation. Also the gaskets ensure easy connection and sealing of the components thus ensuring a high speed assembly. For high speed assembly is recommended to use lubricant on the gasket and spigot pipe end.
