    Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution.. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA (Ductile Iron Pipe Research Association), and was first used in 1922 in Charleston, South Carolina.

  • What are the specifications of ductile iron pipe?

    A ductile iron pipe is created from cast iron that has undergone treatment while in a molten state to enhance its relative malleability, rendering it more resistant to damage typical with traditional cast iron. Ductile iron pipes range in diameter from 3″ to 54″ in 20′ lengths.

    Common Lining Ductile Iron Pipe. Ductile cast iron is kind of alloy of iron, carbon and silicon, in which graphite exists in the type of spherical, generally the size of graphite is 6-7 class, and spheriodization grade of the pipe should be controlled 1-3 class (spheroidization rate is not below 80%). Thus after spheroidization, ductile cast ...

  • What is the pressure rating of ductile iron pipe?

    Although the push-on joint is normally rated for 350 psi, currently there are Ductile Iron Pipe push-on joint pipelines with operating pressures in excess of 1,000 psi. For pressure ratings above 350 psi, contact the Ductile Iron Pipe manufacturers.

  • History of Ductile Iron | McWane Poles

    History of Ductile Iron In the past 400 years cast iron has been used in every conceivable situation where strength and corrosion resistance were needed. From manhole covers to fire hydrants, water pipe, sewer pipe, bridges and buildings, cast iron has weathered the elements and has survived the test of time.


    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. Design Basis The basis of the design standard for Ductile Iron pipe is the long-established fact that Ductile Iron pipe, subjected to

  • What's the Difference Between Pressure Class and Thickness ...

    Oct 12, 2018 · “Thickness Class” Vs “Pressure Class.” When Ductile Iron Pipe was introduced to the market in 1965, replacing “Cast” or “Gray” iron, pipe manufacturers reached a consensus that there should be a standardized protocol for determining wall thickness.

    May 21, 2021 · Modern Ductile iron thickness classes, 50 thru 56, have been around since the mid-'70s. For each single-digit increase in the labeled thickness class, the nominal metal wall thickness requirement for DI pipe diameters of 24-inches and smaller increases by 0.03-inches.

  • Ductile Iron pipe & fabrication – Cohen Pipe

    Ductile Pipe Produced by Cohen. Solid under loads. Ductile iron pipe has a semi-rigid behavior when buried underground–it provides a balanced compromise between the ovality and the wall’s mechanical stress. It is capable of being laid in low and high height cover, and even easier in soil that’s of low rigidity.

    Benefits of ductile iron pipe. Solid under loads. In underground conditions, the ductile cast iron pipe has a semi-rigid behaviour: it offers an excellent compromise between mechanical stress in the wall (small DN) and ovality (large DN). It can be laid in high and low height of cover, and easily in soil of low rigidity.

  • Ductile iron pipe - Wikipedia

    Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. This type of pipe is a direct development of earlier cast iron pipe, which it has superseded. The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron.
