The system made up of polyethylene pipes and related fittings is in line with international standards for the transport of potable water through plastic pipes
The low weight of the PE pipe system components and fittings ensures extremely high manoeuvrability in terms of transport, storage and handling as well as its installation.
It is a fundamental feature of this type of system. System parts can be combined with various special welding technologies available from manufacturers.
The interior surface of the pipes and fittings is extremely smooth so that no material deposits can form inside and the pressure losses are minimized
Polyethylene elasticity allows the pipe section to widen if the transported liquid freezes and thus increases its volume.
Both PE pipes and fittings have a high chemical resistance to most aqueous solutions, to the aggressive action of soil materials, inorganic salts and most acids and bases even at high concentrations and high temperatures.
ABRASION AND CORROSION RESISTANCE
These features allow the transport of fluids at speeds of over 7m / sec without erosion problems, even for acidic or alkaline substances with pH between 1 and 14.
From this point of view, polyethylene pipes are ignited and burn slowly, but they do not maintain combustion and self-extinguish (class C4).
USE IN SEISMIC ZONES
The flexibility and elasticity of polyethylene pipes recommends them for use in areas with seismic risk.
The PE pipe is subject to electrostatic phenomena due to the high resistance of the material. Grounded pipes are subjected to accumulation of loads, due to environment humidity and extensive ground-to-ground contact.
The service life of networks made of polyethylene is overwhelmingly influenced by the laying trench, the foundation bed and the degree of compaction.
The influence of the pipe diameter, the terrain characteristics and the laying depth on the loads and on the pipe deformations, respectively, is negligible. The effect of loads due to vehicle traffic is only seen in the case of laying depths of less than 1m. The quality of the laying works, the material and the degree of compaction are decisive in terms of loads and deformations.
