How Strong is PVC Pipe? (With PVC Strength Charts)

PVC pipe tensile strength can be measured by hanging weight from the pipe until it bends or cracks. As you can see from the chart to the right, tensile strength of PVC pipe increases as the size of the pipe increases. 8" PVC pipe of either schedule is extremely strong for how inexpensive it is.

The strength of concrete pipe is determined by a three edge bearing test (3EB), establishing pipe strength under a severe point load condition. Traditional concrete pipe design uses a bedding factor of about 2 for granular bedding material as a means of equating the 3EB strength to a proposed installation. This means that the measured
