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).
