### What is the difference between DR and SDR? | JM Eagle - …

In other words, for a given DR or SDR, pressure capacity and pipe stiffness remain constant regardless of pipe size. Even though the terms DR and SDR are synonymous, one minor difference between them is that SDR refers only to a particular series of nuers, i.e., 51, 41, 32.5, 26, 21, etc.
