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.
