Flange Details
ANSI/AWWA C110/A21.10, C111/A21.11 or C153/A21.53
The flanges shown are adequate for water service of 250 psi working pressure and should not be confused with class 250 flanges per ANSI B16.1. The bolt circle and the bolt holes match those of ANSI B16.1 class 125. If flanges are required to be made in accordance with other ratings or other standards, this must be specified on the purchase order. 24″ and smaller flanges are rated equal to the fittings to which they are attached and are adequate for water service of greater than 350 psi only with the use of gaskets.
We recommend that ALL Steel Pipes gaskets be used for normal water service.
Facing: Stainless Steel Flanges are plain faced and are finished smooth or with shallow serrations
Back facing: Stainless Steel Flanges may be back faced or spot faced, for compliance with the flange thickness tolerance.
Drilling: Drilling of Stainless Steel flanges can be rotated when required; for those sizes with an even number of bolt holes in each quadrant, the fitting can be rotated 45° with standard drilling.

1 The dimensions of 64″ stainless steel flange correspond with applicable dimensions of 66″ Class E in ANSI/AWWA C207, and 64″ ductile iron flanges can be connected to those flanges.
stainless steel Flanged Fitting Dimensions and Designation of Outlets
ANSI/AWWA C110/A21.10, C153/A21.53, or AMERICAN Standard
See the table below for dimensions for the above fittings. Some of the above fittings are not listed in AWWA C110, but do meet applicable requirements of AWWA C110.
The largest opening establishes the basic size of a reducing fitting. The largest opening is named first, except for bull-head tees and for double-branch bends where both branches are reducing; in these two cases the largest opening is named last.
In the designation of the openings of stainless steel reducing fittings, they should be read in the order indicated by the sequence of the numbers 1, 2, 3 and 4 as shown.
In describing stainless steel tees reducing on the branch only, the first size applies to both outlets on the run. Similarly, for stainless steel crosses with the same size for both run outlets and the same size for both branch outlets, it is necessary to indicate only two sizes. For example: for an 8 × 6 tee or wye – it is not necessary to show 8 × 8 × 6; for an 8 × 6 cross – it is not necessary to show 8 × 8 × 6 x 6.

1 See flanged 90° bends for “K” dimensions.
2 AWWA C110 and C153 do not include data on wyes of any size.
3 Wyes are special. Substituting a pipe with a lateral welded-on outlet may be more economical and offer quicker shipment. A tee with a 45° bend may also offer quicker shipment.
4 For larger branches, use “A” dimensions.
5 For these smaller-diameter reducing tees and crosses, the “A” dimension applies as shown in “cut” of standard tee and cross.
6 For these smaller-diameter reducing wyes, the “D” and “E” dimensions apply as shown in “cut” of standard wye.
7 “F” dimensions for 54″-64″ reducers vary with diameters of reduction.
8 “H” and “J” dimensions for 54″-64″ tees and crosses vary with diameters of reduction.
