ADS N-12 12"-24" Pipe

N-12® Pipe (4" - 60")(100-1500mm)
The hydraulic capabilities of the
product were significantly improved
in 1987 when ADS introduced the first
HDPE drainage pipe to combine an
annular corrugated exterior for
strength with a smooth interior wall
for maximum flow capacity. Named
for its excellent Manning's "n" rating
of 0.012, N-12 pipe was designed
specifically for storm sewers, highways,
airports, and other engineered
construction. Through extensive field
and university testing, ADS engineers
were able to refine the corrugated
wall design for larger diameters
without compromising the pipe's
excellent strength-to-weight ratio. Its
performance and economy have led
to rapid acceptance by contractors
and engineers, and official approval
by state and municipal agencies.
