upvc pipe crushing strength

Rigid pipes, such as those made of concrete, clay or ceramic are unable to flex when loaded and will experience wall crushing and collapse when their load limit is reached this is generally referred to as crush strength and dload, however since flexible conduit reacts differently under a heavy weight load, these terms do not apply
