Stainless Steel Flanged Pipe Fittings are often used in rigid piping conditions such as waste water treatment or filtration and industrial fluid process applications

Stainless Steel Flanged Pipe Fittings

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 Vishal Steel 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 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.
