Hdpe ring deflection
WebJul 1, 2006 · The percentage of ring deflection is based upon strain for a given SDR and is calculated as follows: Y% = dY / OD or Y% = 0.25 * e * SDR where, Y% = Percentage of Ring Deflection (percent) dY = Vertical Deflection (inches) OD = Outside Diameter of the Pipe (6.25 inches for 6 inch SDR-11 HDPE) WebAmerican Concrete Pipe Association – Rigid.
