Lecture 4. Pipes Materials and Loads

Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.

BULLETINJM 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.
