SDR26 Pipes and Fittings
High-Quality Pipework
HIGH QUALITY Polyethylene
A drainage system made of welding polyethylene that is exceptionally elastic and resistant to mechanical stress and vibrations.
The product line consists of pipes and fittings with diameters from 32 to 315 mm and includes a wide range of fittings and service connections to sanitary and sewage systems.
The high PE molecular weight ensures great resistance against cracking due to prolonged use. Moreover, its capacity to afford mechanical stress of significant intensity, makes it suitable for installations in seismic areas.
It also has high resistance to operating temperatures between -40° 70°C, with the ability to manage peak loads up to 95°C. Our pipes and fittings are compliant with standard UNI EN 1519.
- Exceptional elasticity and resistance to mechanical stress and vibrations, ideal for seismic areas
- Exceptional working temperature resistance between -40° and +70°c, against chemical and atmospheric agents
- Excellent resistance to pressure and incidental overpressure
Innovative Technology
High stength and quality
Temperature Resistance
Keeps its characteristics unchanged. Does not break and does not deform permanently in case of water freezing in the pipes, in a temperature range between -40°C up to + 70°C, with the possibility to manage peak loads up to 95°C. Low thermal conductivity: does not tend to form condensation.
Resistance to Mechanical Stress
Elastic enough to stand external stress, impact and deformation,
similar to steel. Provided that certain specific technical rules are observed, can be embedded into the concrete.
Smoothness and Abrasion Resistance
Thanks to the surface structure that prevents the formation of deposits and incrustations.
Resistance to Chemical Agents
Organic and inorganic solvents. At 20°C it is resistant to detergents and acids
used for unclogging sinks and toilets. Absorption of vibrations: thanks to its flexibility and elasticity it is able to withstand small deformations without
breaking (for example: in case of structural settlement in buildings).
Weldability
By means of the butt welding process or by electrofusion.
Weathering Resistance
Thanks to the carbon black it contained, which prevents photo-oxygenation processes due to U.V. rays.
The Anti-Slip Collar
Quality polyethylene pipework
The anti-slip collar also allows the inserting system to be used for the types of drains that currently use welded joints (e.g. horizontal collectors, visible systems, etc.), thereby lowering the labour costs and reducing the incidence of fastening systems.
The anti-slip collar consists of two half-rings made of galvanised steel equipped with rounded teeth on one side that, under the pressure induced by tightening of the clamping screws, deform the protective outer layer of the pipe, taking advantage of the polypropylene’s visco-plastic characteristics.
Small cavities of about 0.5 mm deep are formed, where the teeth provide grip to ensure a mechanical axial seal that is not merely based on friction.
These small cavities formed on the surface do not reduce the resistance of the pipe, because the characteristics of the material itself are not affected by surface incisions and because the incisions do not affect the load-bearing layer
(the central one).
Screws with self-locking nuts ensure the stability of the connection over time without the need for a torque wrench.
It is sufficient to hand-tighten the screws until the perforated lugs come in contact in order to achieve the correct interpenetration of the collar on the surface of the pipe or of the fitting shank and thereby ensure the axial seal of the connection.
