Pipe stiffness explained: PVC and Ductile Iron

By PVC Pipe Association

Pipe stiffness is the measure of a flexible pipe’s resistance to deflection (ovalisation) under load. A flexible pipe is any pipe that can deflect 2% without suffering damage. Both Ductile Iron (DI) and PVC meet this requirement and are considered flexible pipes. Some specifications require DI pipe due to its ‘strength’ in resisting external loads. While this was true in the era of thick-walled DI class pipe, the thinner walls of DI Pressure class pipe have made PVC the stronger option.
