This is a N-12® soil tight drainage pipe made by ADS. The pipe is designed with an integrated bell and spigot system for easy connection. The bells are constructed of reinforced polyethylene so chipping and distortion are minimized. This polyethylene drainage pipe is 15 inches in diameter and 20 feet long.

N-12® ST IB pipe is an excellent drainage pipe selection for storm water and storm sewer construction. The exterior of the N-12® polyethylene pipe is corrugated for added strength and durability. The interior wall is smooth for better hydraulic flow and less abrasion. The pipe is considered soil tight because of the integrated bell and spigot connections. With a little lubricate, two pipes can be pushed together to join in a snap. The bell end spas three corrugation to create a secure joint. The rubber gasket on the spigot meets ASTM F477 standards and helps provide a soil tight seal.
