ADS Dual Wall Pipe, 12"X20Ft

ADS Dual Wall Pipe, 12"X20Ft

The 12850020DW ADS N-12® ST IB Dual Wall Pipe (12″ x 20 ft) is an engineered storm drainage pipe built for high performance with the installation advantages of lightweight HDPE. Manufactured to ASTM F2648, it uses an engineered compound of virgin and recycled HDPE resins and features a built-in bell-and-spigot joint with a factory-installed rubber gasket meeting ASTM F477 for soil-tight sealing. With a smooth interior for hydraulic efficiency and excellent abrasion/corrosion resistance, it’s a proven alternative to reinforced concrete pipe for many stormwater applications.

Country of Origin: Varies by production batch
