Deflection for a given radius and length of deflecting pipe can be calculated as h = l 2 / (2 r) (3) where h = deflection of pipe (m, in) r = radius of bending pipe (m, in) l = length of pipe from fixed position (m, in) Eq. 3 can be modified with eq. 2 to

Pipe 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.
