Dual wall N-12 pipe, with its smooth interior wall and corrugated exterior, offers exceptional hydraulics and strength. Built using application specific high density polyethylene, dual wall N-12 corrugated pipe also provides superior corrosion and abrasion-resistance. This makes it an excellent alternative to reinforced concrete (RCP) and corrugated metal pipe (CMP).
Smooth interior with a Manning's value of 0.012 resulting in increased flow capacity
Inert HDPE material is resistant to the effects of chemicals, abrasion, hot soils, and effluent
Lightweight product for best installed cost and maximizing delivery and installation efficiencies
