Ductile iron flanged fittings manufacturer

Ductile iron flanged fittings price list

Manufacturer of ductile iron flanged pipe, ductile iron pipe flange adapter, ductile iron flanged spool and ductile iron flanged tee in India

Flanged joints for Ductile Iron Pipe and fittings are rated for 250 psi working pressure. However, in accordance with ANSI/AWWA C111/A21.11, 24-inch and smaller flanged joints with Ductile Iron flanges may be rated for a maximum working pressure of 350 psi with the use of special gaskets. These Ductile iron flanged joints are time-proven to be strong, dependable, and bottletight. This is just one of the many reasons why utilities and consulting engineers know that Ductile Iron Pipe is the right decision.

Ductile iron flanged fittings Specification

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.

Ductile Iron Flanged Pipe and Fittings offer proven reliability and in-the-field flexibility for rigid, above-ground applications.

- Perfect for industrial/plant applications.
– Not recommended for underground installations.
- Available in sizes 2" – 64".

Flanged Pipe Standards
4" through 64" ANSI/AWWA C115/A21.15

Facing: Flanges are plain faced and are finished smooth or with shallow serrations

Back facing: Flanges may be back faced or spot faced, for compliance with the flange thickness tolerance.

Drilling: Drilling of 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.
