N-12 pipe is the world standard for corrugated polyethylene drainage pipe. Introduced in 1987, N-12 dual wall pipe with its smooth interior wall and corrugated exterior wall, offers exceptional hydraulics and strength. Built using application specific high-density polyethylene, N-12 corrugated pipe also provides superior corrosion and abrasion resistance making it an excellent alternative to reinforced concrete and corrugated metal pipe. These properties have led to the increasing approval and acceptance of N-12 drainage pipe in storm water applications across the country
