TWIN ECO is the new double-walled corrugated pipe in PP (polypropylene) for non-pressurized underground waste pipes compliant with the UNI EN 13476-3 standard standardized on the internal diameter.
Innovative feature is represented by the joint system which is derived directly from the bar thus maintaining the same profile of the pipe and maintaining the same resistance class SN8 - SN4 KN/m2; moreover, the length of the socket, adapted according to the diameter, guarantees the perfect hydraulic seal of the system, the gasket is in EPDM specifically designed for the profile of the TWIN ECO pipe and guarantees the perfect hydraulic seal of the system at 0.5 bar and 0.3 bar in depression according to the UNI EN 1227 method. TWIN ECO is produced in latest generation HIGH MODULUS Polypropylene Block-Copolymer (PP-HM); PP is the material with the highest development rate in recent years in the ducting sector in Europe and it is also the polymer in which raw material producers have mainly concentrated their investments.
