Q3: What is the difference between Cast Iron and Ductile Iron?
A3: Cast iron is a generic name for any high carbon molten iron poured as a casting. 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. Ductile Iron is a specific type of cast iron in which the free graphite is in the shape of nodules or spheroids. Although nearly identical chemically, the two irons are quite different metallurgically. The current standard for Ductile Iron Pipe (ANSI / AWWA A21.51 / C151) requires a minimum grade of 60-42-10 (60,000psi Ultimate Tensile Strength, 42,000psi Yield Strength, and 10% Elongation). Although Cast Iron was the best engineering material available for pipe production for nearly five hundred years, the development of Ductile Iron Pipe provides a far superior product.
Q4: How much thermal expansion should I allow for?
A4: The linear expansion of ductile iron pipe as a result of thermal effects is very small, with ductile iron expanding less than concrete. For rubber gasketed joints and mechanical joints assembled in accordance with the manufacturer’s instructions, there is enough clearance from the face of the plain end of the pipe to the back of the bell to account for significant thermal growth before beginning to make metal-to-metal contact. Except for very long runs of exposed piping, particularly if flow is intermittent, thermal expansion is usually not a concern.
Q5: What is the maximum velocity recommended for cement-lined Ductile Iron pipe?
A5: Although there are differing opinions on this subject, a conservative maximum velocity for design purposes is 7 fps (feet per second). Ductile Iron pipe may be rated as high as 350 psi service. A pipeline operating at 7 fps velocity could account for a 350 psi pressure surge (7fps X 50 psi/fps). Adding a potential surge pressure equal to the pressure rating of the pipe encroaches significantly on the safety factor. Exceeding 7 fps velocity could produce potentially damaging surge pressure.
Q6: Can cement-mortar linings be repaired in the field?
A6: Repair is achieved by first cutting out the defective or damaged lining to the metal so that the edges of the lining not removed are reasonably perpendicular to the pipe wall or slightly undercut. A stiff mortar is then prepared and applied to the cutout area and troweled smooth with adjoining lining. To provide for proper curing of patches by preventing too rapid of a moisture loss from the mortar, the patched area is normally seal-coated immediately after any surface water evaporates, or alternatively the area is kept moist (e.g. with wet rags or burlap over the area or with the ends of the pipe or fitting taped over with plastic film, etc.). Of course, in potable water-related applications, no patch or curing components should be used in the repair that would negatively affect health or water quality.

- Q:How do ductile iron pipes perform in high-temperature water applications?
- Ductile iron pipes possess remarkable strength, durability, and exceptional mechanical properties, rendering them suitable for diverse applications. However, certain factors must be taken into consideration when utilizing them in high-temperature water scenarios. Typically, ductile iron pipes exhibit satisfactory performance in high-temperature water settings up to a specific threshold. The exact temperature constraint hinges on the particular grade of ductile iron employed and the duration of exposure to elevated temperatures. Generally, ductile iron pipes can endure temperatures ranging from 350 to 400 degrees Fahrenheit for brief periods without suffering significant deterioration or loss of strength. Nevertheless, it is crucial to acknowledge that prolonged exposure to high temperatures can have adverse effects on ductile iron pipes. When subjected to elevated temperatures, these pipes may undergo thermal degradation, which can result in diminished mechanical properties, heightened brittleness, and even eventual cracking or failure. To mitigate the risks associated with high-temperature water applications, several precautionary measures can be implemented. Firstly, selecting a suitable grade of ductile iron with an elevated temperature tolerance can enhance the pipes' performance. Secondly, incorporating adequate insulation or heat shielding measures can minimize direct heat transfer to the pipes, thereby reducing the likelihood of thermal degradation. Furthermore, frequent monitoring and maintenance of ductile iron pipes utilized in high-temperature water settings are crucial to promptly identify any indications of degradation or damage and take appropriate remedial actions to prevent failure. In conclusion, although ductile iron pipes typically perform well in high-temperature water applications, it is imperative to thoroughly evaluate the specific conditions and requirements of the application to ensure their sustained performance and integrity.
- Q:How do ductile iron pipes handle ground movement in earthquake-prone areas?
- Ductile iron pipes are known for their excellent resistance to ground movement, making them a reliable choice for earthquake-prone areas. These pipes are designed to withstand external forces, including the ground shifting and movement caused by seismic activities. The flexibility of ductile iron pipes allows them to absorb and distribute the energy generated during ground movement. This flexibility is achieved due to the unique composition of ductile iron, which includes nodular graphite in its microstructure. The nodular graphite provides ductility and resilience to the pipe, allowing it to deform under stress without fracturing. When an earthquake occurs and the ground starts to move, ductile iron pipes can adapt to the changing conditions. They have the ability to elongate, compress, and bend, thus reducing the risk of pipe failure. This characteristic is crucial in earthquake-prone areas, as it helps prevent catastrophic failures and water loss that can occur with more rigid pipe materials. Moreover, ductile iron pipes have a high level of joint integrity, which further enhances their ability to handle ground movement during seismic events.
