Applications of Ductile cast iron. The Modulus of Elasticity for Ductile Iron, measured in tension, varies from 23.5 to 24.5 x 10 6 psi (162 - 170 GPa). Its chemical components did not have strict range for many material standards, however, its range should be useful for buyers to evaluate the quality of cast iron. U.S. Standards & Specification Shin Nan ductile iron pipes and fittings for water and sewerage systems are manufactured according to EN 545 / EN 598 / EN 969 / ISO 2531 and under the quality control system of ISO 9001 for quality assurance. The inside diameters are as given in table 1. Ductile iron pipes and fittings have high corrosion resistance, are lined with cement or resins, and usually coated with zinc plus bitumen paint, which solves the problems of corrosion that grey iron pipes or steel pipes can’t solve. The standard nominal sizes DN of pipes … For over 100 years U.S. Fastite Joint Pipe: Fastite Joint Push-Bar Pipe: Mechanical Joint Pipe: Coupling Gland Joint: Earthquake Joint System: Fastite Joint Pipe With Fast-Grip Gasket: Fastite Joint Pipe With Amarillo Fast-Grip Gasket: Field Flex-Ring Joint Pipe: Flex-Lok Ball Joint Pipe: Flex-Ring Joint Pipe: Grooved and Shouldered Joints: Lok-Ring Joint Pipe Ductile iron pipe is lighter, stronger, and more durable than cast iron. Ductile Iron Pipe: It is a pipe made of ductile cast iron commonly used for potable water transmission and distribution. The corrosion resistance of Ductile iron pipe has been proven in a wide variety of accelerated tests to be at least the equal of gray cast iron. Please remember the chemical components are only a reference, … Ductile Iron Pipe. Ductile Iron pipe is a centrifugally cast product. Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile's high degree of dependability is primarily due to its high strength, durability, and impact and corrosion resistance. Above 1.7% carbon, the carbon cannot all be dissolved in the iron structure and consequently solidifies in the form of a secondary phase, either as graphite (pure C), or iron carbide (Fe3C). Ductile Iron, like most ferrous materials, exhibits fracture behaviour which varies according to composition, microstructure, temperature, strain rate, and stress state. A controlled amount of molten iron is introduced into the rotating mold, which generates a centrifugal force that holds the iron … Pipe has supplied the critical components to ensure our nation's water and sewer infrastructure is built to last. Design Basis The basis of the design standard for Ductile Iron pipe is the long-established fact that Ductile Iron pipe, subjected to They can be obtained in 3″ – 24″, 3″ – 36″ or 3″ – 64″ options, depending on the manufacturer. These weights are based on minimum class (thickness class 51 for 3" and 4" and class 50 for 6" through 54") ductile iron pipe with minimum thickness standard cement lining as specified in awwa c104 and on weight of water of 62.4 Pounds per cubic foot. Ductile Iron Chemical Components. Ductile Iron Pipe Ductile iron is often used as a pipe as the spheroidal or nodular nature of the graphite that makes ductile iron twice the strength of cast iron. Ductile Iron Pipe. This new standard included considerations to the inherent strength advantage of ductile iron over its cast iron predecessor. for the Thickness Design of Ductile Iron Pipe (ANSI/AWWA C150/A21.50) has evolved. No more thorough and comprehensive standard design procedure exists for any piping material. In ductile iron, the graphite form is spheroidal, or nodular; in cast iron, it is in a flake form. cast iron or ductile iron: 1.7 to 5% C Below 1.7 % carbon, solidification produces an austenitic single phase material, with the carbon present in the structure in solid solution. Pipe is the recognized leader in highly engineered pipe products for water and wastewater systems. Ductile iron is also called as nodular iron or SG iron. Ductile iron is made by adding a closely controlled amount of magnesium alloy to a molten iron of low phosphorous and low sulfur content. Ductile iron pipes are available in different sizes, lengths and types. Ductile Iron has minimum strength requirements of 60,000 psi tensile strength, 42,000 psi yield strength, and 10 percent minimum elongation.
