Bar-Wrapped Cylinder Concrete Pipe

N/A303, a bar-wrapped cylinder concrete pipe, combines the physical strength of steel with the structural and protective properties of high strength cement mortar. A round bar is helically wound around the steel cylinder and all surfaces are encased in cement mortar. This composite pipe reacts as a unit when resisting internal pressure and external loads. Diameters 24 in. and smaller are rigid and require minimal bedding, while larger diameters depend on developing supporting strength form the lateral pressure of the soil backfill as the pipe deflects under load.
