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
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.
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.
Piping system inside is manufactured in a bright color that provides a very good visibility to facilitate inspection with video cameras.
