AMERICAN Ductile Iron Flanged Fittings The principal standard covering flanged fittings is ANSI/AWWA C110/ 54"–64" flanged fittings are covered in ANSI/ AWWA C153/ These and other standards are referenced throughout this section either by the full ANSI/AWWA designation or by only the AWWA numbering, such as AWWA C110 or C153.

805506 Ductile Iron. DuraBar 805506 ductile iron will contain nodular graphite in a matrix of ferrite and pearlite. The pearlite/ferrite structure provides higher wear resistance and strength when compared to a ferrite grade of ductile iron. This material is readily machinable with good surface finishes.

Flanged Joint ductile iron fittings are the industry standard for above ground ductile iron piping systems. We stock Flanged fittings in sizes 3" – 64" conforming to the AWWA C110 standard. We stock them as cement lined, glass lined, and Protecto 401 lined.

Ductileiron pipe and related products convey water from its source to its point of use through the myriad stages of storage, transmission (Figure 11), filtration, pumping, chemical treatment, and distribution.

DuraBar 654512 ductile iron contains nodular graphite in a matrix of ferrite with small amounts of pearlite. Our most popular DuraBar grade, 654512 ductile iron has excellent machinability with good surface finishes, optimal impact strengths, fatigue properties, .

Ductile Iron water pipe consists of the mains and branches that serve residential, commercial, and industrial structures. Watermains are pressure pipe systems so they are more adaptable to existing underground or above ground obstructions (via fittings) than gravity pipe systems.

Ductile iron, also referred to as nodular iron or spheroidal graphite iron, was patented in 1948. After a decade of intensive development work in the 1950s, ductile iron had a phenomenal ninefold increase in use as an engineering material during the 1960s, and the rapid increase in .

Ductile Iron offers the castability, machinability, and corrosion resistance of gray iron while adding the high strength, ductility, and hardening ability of steel. Our ductile iron castings are well known throughout the industry for highimpact resistance and a high modulus of elasticity and strength, resulting in heavier load capacity with less deflection.

Jun 17, 2015· Impact Ductile iron has a greater resistance to impacts, and is able to resist a minimum of 7 foot pounds of impact (versus 2 pounds of impact for gray iron). Thermal Conductivity – Ductile iron has a lower thermal conductivity than gray iron. Vibration Dampening Gray iron dampens vibrations more effectively than ductile iron.

WSSC, like most water utilities used cast iron pipe until the mid to late 1960s. By the early 1970s, WSSC was using ductile iron pipe. Some classes of ductile iron pipe manufactured in the 1970s were notorious for being very thin, resulting in a life expectancy of 4050 years.

DUCTILE IRON CHAINWHEELS allow operation of valves, actuators, or gear boxes in high, hardtoreach locations by means of a slight pull on the chain. Universal design allows Chainwheel to be clamped to handwheel, or pinned directly to valve stem. Ductile iron Chainwheels are furnished with plated steel attachment hardware for clamping to handwheel.

Definition of irons. cast iron or ductile iron: to 5% C Below % carbon, solidification produces an austenitic single phase material, with the carbon present in the structure in solid solution. Above % carbon, the carbon cannot all be dissolved in the iron structure and consequently solidifies in the form of a secondary phase,...

Ductile Iron ASTM A536. Ductile has great vibration damping and corrosion resistance properties. Ductile Iron has a great strength to weight ratio. Finally Ductile Iron can be made for a much lower cost than steel. One of the reasons for this lower cost can be attributed to the gross material being used is less for casting ductile iron vs steel.

Ductile Iron Poles McWane Poles is a product line of McWane, Inc. McWane is a familyowned company that has been serving customers in the iron and ductile iron industries since 1921. Initial efforts on McWane Poles began in 2007 with research and development of a tapered pole design for centrifugal casting of ductile iron.

Ductile Iron Features Applications. Furthermore, correctly designed ductile iron castings prevent the formation of external shrinkage (or short cast) defects in the cast part. A direct example of this is the automobile industry's wide use of ductile iron in several applications, including safety critical components in the steering and braking systems.

2 DUCTILEIRON PIPE AND FITTINGS had been achieved in producing lowercost iron by using coke instead of charcoal. Following this success, the more progressive cities began to install castiron mains.
