  • pvc water pipe allowable deflection connection

C900 PVC Water MainPipe deflection can occur in C900 pipe when it’s subjected to excessive vertical loading. Deflection is heavily influenced by Pipe Stiffness, Soil Density, and Pipe Loading. Also, the thicker the pipe wall (i.e. lower the dimension ratio) the more resistant to deflection.Schedule 80 PVC and CPVC Schedule 40 PVC Technical Manual …Properties Unit PVC CPVC Remarks ASTM Test Water…

    The basic piping practice to limit pipe deflection between supports to 1” or 1/2 the nominal pipe diameter, whichever is the smaller. The most important reason for limiting deflection is to make the pipe stiff enough, that is , of high enough natural frequency, to avoid large amplitude response under any …
