What Is Ductile Iron Reducer?
A ductile iron reducer is a fitting that reduces the nominal bore size from a bigger diameter to a smaller inner dimension. A Ductile Iron Reducer allows change in pipe size to connect different sized pipes to meet hydraulic flow requirements. The Ductile Iron Pipe Reducers is typically ordered in concentric and eccentric specifications. The reducers ensure a gradual drop of media in the system. The Di Reducers helps in meeting the requirements of different piping systems as they are available in a range of sizes. The common grades of the Ductile Iron Reducer Fittings are ASTM A536, grade 60, 65, and 80. These fittings have greater strength across a range of environments.

- 54 inch to 64 inch reducer fittings are rated for only 150 psi in AWWA C153
- Ductile Iron Eccentric reducers are not available 54 inch and larger.
How To Calculate Di Eccentric Reducer Thickness?
The Di eccentric reducer is produced by dividing the plate volume by its surface area. The Di Eccentric Reducers thickness can also be calculated using the thickness calculator.
Commercial Benefits Of Ductile Iron Reducer Fittings
- The ductile iron reducer has high strength due to its spheroidal graphite microstructure.
- The 6 X 4 Ductile Iron Reducer has excellent beam strength and greater resistance to impact and traffic loads.
- The versatile 4 X 2 Ductile Iron Reducers has excellent ductility and is lighter and easy to manoeuvre.
- The reducers have simplistic joints that accommodate some angular deflection.
- The reducers have simplistic joints that accommodate some angular deflection.

How To Make Ductile Iron Concentric Reducer From Pipe?
A ductile iron concentric reducer can be produced customizing a pipe grade. The Di Concentric Reducer can be formed as the pipe is cut in exact size as per requirements. This can be followed by grooving the Ductile Iron Concentric Reducers for better flexibility and tolerance.
