Standard dimension ratio

Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall.[1]

Common nominations are SDR11, SDR17 and SDR34. Pipes with a lower SDR can withstand higher pressures.

SDR=\frac{d_o}{s}

d_o Pipe outside diameter

s Pipe wall thickness
