Why Ductile Iron?

NIBCO is the largest United States manufacturer of pressure rated Ductile Iron Valves. NIBCOs Ductile Iron multi-turnvalves are ideal for a wide variety of services: hydrocarbons, chemical, marine, fire protection services, pulp and paperapplications where cast iron and/or cast steel valves could be installed.

Ductile Iron, also known as nodular iron, was developed about 50 years ago as a substitute for steel. Cast steel contains

carbon of less than .3% by weight, while cast and ductile irons have at least 3% total carbon. This low carbon content incast steel does not allow the carbon to form as free graphite resulting in a laminate type of structure. The natural form ofcarbon in cast iron is the free graphite flake form. In Ductile Iron, this graphite flake is modified by a specialized treatmentprocess to form tiny spheres or nodules. These modified graphite nodules provide Ductile Iron with physical propertiesgreater than cast iron and comparable to steel. It is this nodular microstructure of carbon in Ductile Iron which produceshigh ductility and shock resistance while the flake form of cast iron results in no malleability. Optimum ductility is obtainedwith a ferritic matrix, therefore, all NIBCOs Ductile Iron pressure containing parts are treated with a ferritizing annealingcycle. In Ductile Iron spheroidal nodules also eliminate the crack effect of flake graphite which is exhibited in cast iron. Inmicroscopic photos of Ductile Iron, cracks can be seen traveling to a graphite nodule and stopping. These graphite sphe-roids are know as crack arresters in the Ductile Iron industry because of their ability to stop cracks in their tracks.

In some circles, Ductile Iron is known as the metal that is the Best of both worlds meaning that Ductile Ironcombines the superior strength of cast steel with the excellent corrosion resistance of cast iron.

Ductile Iron vs. Cast (Gray) IronThe strength of Ductile Iron when compared to cast iron is overwhelming. Ductile Iron tensile strength is 60k versus castiron at 31k. Ductile Iron has a yield strength of 40k, whereas cast iron exhibits no yield, only ultimate fracture. Ductile Ironstrength to cost ratio offers greater value for a marginal increase in cost over cast iron. (See page 5 for a complete com-parison of mechanicals.) Ductile Iron offers excellent corrosion resistance that is equivalent to cast iron.

Ductile Iron vs. Cast Steel

The strengths of Ductile Iron and cast steel are comparable. Ductile Iron has a higher minimum yield strength at 40k ver-sus cast steel at 36k. (See page 5 for a more complete comparison of mechanicals.) Ductile Iron has corrosion and oxi-dation resistance that surpasses cast steel in most general utility service applications, i.e.water, saltwater, steam. Becauseof Ductile Irons spheroidal graphite microstructure, Ductile Iron is superior to steel in its ability to deaden vibration andtherefore reduce stresses. An important factor in selecting Ductile Iron over cast steel is cost. The lower expense of Ductile

Iron results from readily available materials, foundry operation efficiencies and reduced machining costs of Ductile Iron.

NOTE: For our metal comparison, NIBCO has chosen to use ASTM A-395 Ductile Iron, ASTM A-126 Cast Iron and ASTM A-216 WCB Cast Steel.Wherever Cast Iron is listed, we are referring to Gray Iron.

Featur es and Benefits

Constr uction Featur esFlanges NIBCO Ductile Iron Valves come standard ANSI B16.42 Class 150 flanges and the same

end-to-end dimensions as Class 125 iron or Class 150 steel valves. Thus Ductile Ironvalves can easily replace cast iron or steel valves. NIBCO also offers PN10/16 flanges perBS 4504 and compliant to BS 5150 face to face dimensions.

Trim Bronze ASTM B584, 316 Stainless Steel

Test Pressures All NIBCO Ductile Iron Valves are tested to MSS requirements in our ISO 9002 qualitycertified manufacturing plant in Blytheville Arkansas.

Color NIBCO Ductile Iron valves are painted green in compliance with API 604.

Strength Ductile Iron is a very strong material when compared to cast iron and comparable to caststeel. Ductile Iron has a higher yield strength than cast steel 40K vs. 30K. The strength ofDuctile Iron when compared to cast iron is overwhelming. Ductile Iron tensile strength is

60K vs Cast Iron at 31K. Ductile Iron has yield strength of 40K and cast iron has none.Corrosion Resistance Ductile Iron has a corrosion and oxidation resistance in most cases that surpasses cast

steel and is slightly better than cast iron. Oxide penetration can severely affect the strengthand performance of valves.

Low Transition Temps Ferrous metals are subject to brittle fractures with severe temperature changes. The chem-ical composition of NIBCOs Ductile Iron provides transition temperatures to -20F. Thisproperty is important if physical shock loading is present in cold weather applications.

Cost Effective These unique characteristics make Ductile Iron a cost-effective option for 150 psi steamservice as well as hydrocarbon processing up to 650F/343C.

ApplicationsSteam Service Ductile Iron gate, globe and check valves are excellent choices for 150 psi steam service.

Available with B-584 bronze trim and CF8M SS trim.

Hydrocarbon Service Ductile Iron is an acceptable substitute for cast steel in a wide range of processing servic-es both on the production and refining side up to 650F/343C.

General Service Ductile Iron can substitute for standard Class 125 cast iron where there may be concernswith potential stresses and a stronger material is desired, i.e. in situations of unusual pipemovement due to the system or external forces, such as cold weather, earthquakes, etc.

Can substitute for Class 250 cast iron for intermediate pressure services using Class 150

flanges up to 285 psi wwp. (Should save on valve and flange costs.)Ductile Iron is a good choice for general service, fire protection and Hi-rise applications.

Has a higher application temperature than Teflon seated flanged ball valves.

Marine Service For shipboard application and tanker piping, many marine agencies recommend the use ofDuctile Iron Valves because of its resistance to shock, vibration and superior corrosion-resistant properties.

VALVES 2 1/2" AND LARGER 285 PSI CWP APPLICATION

GLOSSARY OF TERMSDuctility: The ability of a material to become permanently deformed - stretched, drawn, or hammered without

failure while maintaining an appreciable load.

Tensile strength: Measures in force per unit area (i.e. pounds per square inch-psi) the ultimate stress that can be with-stood by a material in tension prior to failure.

Yield strength: Measures in force per unit area the stress at which a material will undergo a permanent change inshape (plastic deformation) in response to an applied force.

Elongation: Measures by percentage the amount of plastic deformation a material will exhibit in response to a forceapplied in tension.

Oxide penetration: The depth of material deterioration or loss displayed along the surface of a metal that is exposed tohighly corrosive (oxidizing) environment.

Gate Valves Valves to be Class 150 and 285 psi CWP, tested in accordance with Manufacturers StandardizationSociety, flanged, bolted bonnet, OS&Y, Ductile Iron body, 316 SS trimmed, with body and bonnetconforming to ASTM A-395 Ductile Iron. Packing and gaskets to be non-asbestos.
