This results in different pressure ratings for each type of PVC pipe. For example, a 4-inch-diameter SCH 80 PVC pipe has a pressure rating of 320 psi, compared to a 4-inch diameter SCH 40 PVC pipe which has a pressure rating of only 220 psi. As a more rigid pipe, the strength of a PVC pipe is a result of the pipe itself.
