High resistance pipes with triple layer wall.

Sistema tubazioni PP Ecoforte

High resistance pipes with triple layer wall in high modulus polypropylene (PP-HM) for non-pressure underground sewage applications, internal walls are RAL 8023, internal are RAL 9003.

Molded and thermoformed fittings in compact PP-HM, brick colour RAL 8023. The use of PP-HM allows the production of a high performance system in terms of resistance to loads, buckling and internal and external abrasion.
The PP Ecoforte system complies with European Standard UNI EN 13476-2:2008.

The system provides a wide range of accessories to achieve an efficient sewer system.

The PP Ecoforte System

Long service life of the entire system composed of pipes and fittings.

Breakage and crushing resistance due to dynamic stress. Flexibility that allows the pipe to withstand the intense pressure caused by burial in the ground and the passage of vehicles.

The system’s mechanical resistance even at low temperatures (resilience) -10°C +95°C intermittent, allows handling of pipes and fittings without breakages, as prescribed by European Standard EN 1411.

The wide range of diameters (from 110 to 500 mm) allows use in all types of constructions: residential, road and industrial. Ring stiffness classes SN4, SN8, SN12, and SN16.

Socket coupling system with blocked Forsheda Din-Lock® for the entire series.
