WebADDITIONAL CONSIDERATIONS FOR PVC PIPE AND DR • A PVC pipe with a higher DR has a thinner wall. This means that as DR increases, the pipe will have less pressure capacity and lower pipe stiffness. • By definition, DR is applicable only to solid-wall pipe and has no relevance for profile-wall products. The bottom line: DR and SDR are identical. WebFor other types of pipe, like PEX and CPVC, wall thickness is designated by the standard dimension ratio (SDR), which is defined as the ratio of the OD to wall thickness and has a typical range of 7.4 to 13.5.
