Ductile Iron (DI pipe) was first used in the United States as early as 1950's. Since iron pipe was one of the earliest pipe materials to be used in modern water works and wastewater systems, most early fittings and couplings were designed to be used on Grey Cast and then Ductile iron pipe. Frequently Asked Questions | Ductile Iron Installation Standard (belled) Ductile Iron Pipe, manufactured in accordance with ANSI/AWWA C151/A21.51, has been installed by utilities using various pipe pushing methods and directional drilling. The methods involve forming a hole a little larger than the outside diameter of the pipe joint. The Ductile Iron Pipe is then pushed or pulled through the hole. Flanged Pipe Ductile Iron Flanged Pipe for Water and Other Liquids. Flanged pipe and fittings are typical components in rigid piping systems. Such systems are ANSI /AWWA Standards particularly suited for above ground installation in the following: water filtration plants, sewage disposal plants, wastewater treatment plants, pumping stations and industrial plants, per AWWA C115/21.15.
Ductile Iron Pipe Joints and Their Uses. Flanged Ductile Iron Pipe and Fittings. Gasket Materials Used for Ductile Iron Pipe in Water and Sewage Service. APPLICATIONS Bridge Crossings with Ductile Iron Pipe Ductile Iron Pipe is centrifugally cast in 18- and 20-foot nominal laying lengths. Nominal diameters range from 3 to 64 inches, with a variety of pressure and special thickness classes. Although Ductile Iron Pipe is usually furnished with a cement-mortar lining, optional internal linings also are available for a wide range of special applications. WSSC uses Ductile Iron to Manage Sustainability ductile iron pipe joints and their uses - U.S. Pipe WSSC uses Ductile Iron to Manage Sustainability and Engineering. See article here: WSSC AWWA Journal Article June 2017 The Washington Suburban Sanitary Commission (WSSC) in Laurel, Md., recently changed its standard pipe material from ductile iron pipe (DIP) to zinc-coated DIP.This change was recommended by the agencys engineering staff to continue to improve the sustainability of the ductile iron pipe joints and their uses
Pipe Fittings Explained: Fitting Materials and Manufacturing Processes Cast and malleable iron. Fittings for cast iron pipe fall under hubless and bell-and-spigot styles. . Hubless designs rely on elastomeric couplers that are secured to the outer diameters of the pipe or fitting by clamps, usually a stainless steel band clamp that compresses the elastomeric material and forms a Three Common Questions About Ductile Iron Pipe Gaskets ductile iron pipe joints and their uses Push-on, restrained joint pipe -- whether TR Flex manufactured by McWane Ductile and U.S. Pipe, Flex Ring, manufactured by American Cast Iron Pipe, or HP Lok, manufactured by U.S. Pipe -- use the same gasket as used by the manufacturer in their corresponding non-restrained joint pipe (i.e. Tyton Joint gasket for McWane Ductile and U.S ductile iron pipe joints and their uses TYTON Fittings - U.S. Pipe Ductile Iron push-on and mechanical joints are covered in ANSI/AWWA C111/A21.11 "Rubber-Gasket Joints for Ductile-Iron Pressure Pipe and Fittings." Section 4.2.2 of that standard states: "The mechanical and push-on joints shall have the same pressure rating as the pipe or fitting of which they are a part."
Ductile iron pipeline systems, including pipes, fittings, accessories and joints, consist of various materials.When used for conveying water intended for human consumption, the materials in contact with the water shall meet the relevant requirements of the national standards or regulations in the country of use with respect to effect on water quality. Malleable vs. Ductile Iron - PVC Fittings Online Uses for Ductile Iron. Ductile iron is used for much of the same type of items as ductile iron, as it is also very strong and workable (or ductile). The uses for ductile iron include pipe fittings, industrial piping, liquid fittings, strainers, and more. As mentioned before, ductile iron is cheaper to produce. Joining Ductile or Cast Iron Pipe - Little P.Eng. Joint separation is prevented by the use of hardened steel inserts (teeth) which grab the mating pipe ends. Flanged Joints. Flanged ductile or cast-iron pipe is used above ground for low and intermediate pressures in water-pumping stations, gas works, power and industrial plants, oil refineries, booster stations for water, and gas and oil ductile iron pipe joints and their uses
Ductile Iron Pipe The first Ductile Iron Pipe was cast experimentally in 1948. Years of metallurgical, casting, and quality control refinement followed, and in 1955 Ductile Iron Pipe was introduced into the marketplace. Its phenomenal strength and impact resistance compared to Gray Iron, along with many other advantages, Fittings - U.S. Pipe When used to refer to pipe, cast iron (sometimes called gray iron) is a specific type in which the free graphite (Carbon) is in the shape of flakes. Cast Iron pipe were introduced into the United States in 1817. Ductile Iron is a specific type of cast iron in which the free graphite is in the shape of nodules or spheroids.
