# minimum crushing strength of concrete pipes

### BULLETIN - JM Eagle

weight and vehicular traffic. Rigid pipes, such as those made of concrete or clay, do not perceptibly flex when loaded and experience wall crushing when their load limit is reached. This mode of failure for rigid pipes has given rise to the terms “crush strength” and “D-Load”, but these terms do not apply to PVC pipes.
