Our industry standard bell and spigot joint system eliminates the need for separate couplers without giving up strength or superior hydraulic flow. The ease of installation combined with its light weight and longer sections ensures project savings over heavier materials such as corrugated metal pipe (CMP). Using HDPE pipe can lower your overall project construction costs by allowing for utilization of smaller crews, smaller equipment, faster installation, and easier handling of lightweight pipe. HDPE pipe is an eco-friendly alternative in many storm water applications. All bell and spigot connections shall meet the watertight joint function requirements of AASHTO.
