N-12® Dual Wall Pipe
The Dual Wall N-12 pipe, with its smooth interiorWall 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).
