    Unit price per 

The 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).


N-12 pipe is available in soil tight (ST), water tight (WT) and plain end, all of which offer joint options of bell and spigot design, gasket, bell wrap or pressure-rated 10.8 psi coupler. It's available with multiple joining systems, and provides corrugated-pipe strength and smooth interior wall hydraulics for increased flow capacity, in a lifetime package.
