Collapse Strength of PVC Pipe

The following is the ASTM F 480 formula for determining the collapse strength of PVC pipe manufactured in accordance with said standards.

Pc Formula

Where:

Pc = Collapse pressure of PVC pipe (psi)

E = Young's Modulus for PVC (4x105)

u = Poisson's Ratio (0.33)

Do = Outside diameter of pipe (inches)

t = Wall thickness (inches)

Calculate Collapse Strength of PVC Pipe

Input pipe outside diameter
inches
mm
Input pipe wall thickness
inches mm
Input Young's Modulus typically = 4x105
Input Poisson's Ratio
typically = 0.33
Theoretical collapse strength of PVC pipe psi kg/cm2
