N-12 Pipe

N-12® pipe is the world standard for corrugated polyethylene drainage pipe. Introduced in 1987, N-12 pipe with its smooth interior wall and corrugated exterior wall, offers exceptional hydraulics and strength. Built using application specific high-density polyethylene, N-12 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 pipe in storm water applications across the country.

N-12 IB ST (Soil-Tight)

Available in diameters from 4" to 60", N-12 pipe is replacing reinforced concrete pipe as a preferred product for storm water applications.The reinforced polyethylene bell of N-12 IB ST pipe minimizes distortion. Chipping and cracking common to concrete pipe bells, is eliminated. Today N-12 IB ST pipe is the best soil tight joint for storm sewers on the market.

N-12 IB WT (Water-Tight)

N-12 IB WT's ceramic/polymer composite joint combined with HDPE's excellent abrasion and corrosion resistance, produces a joint with excellent strength. The wide proprietary ceramic/polymer composite is fused to the outside wall of the built-in bell, improving the joint's integrity and tolerance control.
