ADS N-12 Solid Dual-Wall HDPE Drainage Pipe — 15 in x 20 ft

ADS N-12® dual-wall pipe pairs a corrugated exterior for structural strength with a smooth interior for excellent flow, making it a proven, cost-effective alternative to reinforced concrete (RCP) and corrugated metal pipe (CMP) in gravity-flow stormwater and drainage systems. This 15 in pipe ships in 20 ft lengths and is engineered for a minimum 100-year design service life.
