Notes:
*The minimum dimension "B" for 42"-64" wall castings with threaded-on (AWWA C115) flange would be as follows: for 42", B = 6"; for 48", B = 6 1/2 "; for 54"-64", B = 7 1/4 ".
Dimensions are based on standard mechanical joints per AWWA C111 and standard flanges per AWWA C110.
Wall piping with MJ bells or flanges having "A" and "B" dimensions shorter than those above, e.g., wall pipes with bell faces often placed flush with concrete form work, should be specified to be tapped for studs.
"A" and "C" dimensions for 14"-48" sizes apply to MJ castings only.
