Dimensions are in inches.  Weights are in pounds.

Notes: 
Hub flanges are to be used on pipe that has an OD equal to the nominal pipe size in the first column.    *Pressure Ratings are from AWWA Table 3 Class D.  Pressure rating at atmospheric temperature: sizes 4-12 in. inclusive, 175 psi; sizes larger than 12 in., 150 psi.  These flanges have the same diameter and drilling as ANSI/ASME B16.1 class 125 cast-iron flanges.  In sizes 24in. and smaller they also match up to ANSI/ASME B16.5 150-psi standard for steel flanges.
