Ductile iron pipe is sized according to a dimensionless term known as the Pipe Size or Nominal Diameter (known by its French abbreviation, DN). This is roughly equivalent to the pipe's internal diameter in inches or millimeters. However, it is the external diameter of the pipe that is kept constant between changes in wall thickness, in order to maintain compatibility in joints and fittings. Consequently the internal diameter varies, sometimes significantly, from its nominal size. Nominal pipe sizes vary from 3 inches up to 64 inches, in increments of at least 1 inch, in the USA.

Pipe dimensions are standardised to the mutually incompatible AWWA C151 (U.S. Customary Units) in the USA, ISO 2531 / EN 545/598 (metric) in Europe, and AS/NZS 2280 (metric) in Australia and New Zealand. Although both metric, European and Australian are not compatible and pipes of identical nominal diameters have quite different dimensions.

Flanges are flat rings around the end of pipes which mate with an equivalent flange from another pipe, the two being held together by bolts usually passed through holes drilled through the flanges. A deformable gasket, usually elastomeric, placed between raised faces on the mating flanges provides the seal. Flanges are designed to a large number of specifications that differ because of dimensional variations in pipes sizes and pressure requirements, and because of independent standards development. In the U.S. flanges are either threaded or welded onto the pipe. In the European market flanges are usually welded on to the pipe. In the U.S. flanges are available in a standard 125 lb. bolt pattern as well as a 250 lb (and heavier) bolt pattern (steel bolt pattern). Both are usually rated at 250 psi (1,700 kPa). A flanged joint is rigid and can bear both tension and compression as well as a limited degree of shear and bending. It also can be dismantled after assembly. Due to the rigid nature of the joint and the risk of excessive bending moment being imposed, it is advised that flanged pipework is not buried.

Current flange standards used in the water industry are ANSI B16.1 in the USA, EN 1092 in Europe, and AS/NZS 4087 in Australia and New Zealand.

Ductile iron pipe is somewhat resistant to internal corrosion in potable water and less aggressive forms of sewage. However, even where pipe material loss and consequently pipe wall reduction is slow, the deposition of corrosion products on the internal pipe wall can reduce the effective internal diameter. A variety of linings are available to reduce or eliminate corrosion, including cement mortar, polyurethane and polyethylene. Of these, cement mortar lining is by far the most common.

Polyurethane (Plastic wrap) marginally protects piping made of ductile cast iron against corrosion and ensures meeting hygienic standards for drinking water at the same time in the early years. Polyurethane is used for both the inside lining and the outside coating. Because of polyurethane's elasticity, the coating remains intact even if the pipe is deformed. A major problem is that the poly wrap is not able to be uniformly installed or even installed without rips and creates isolated corrosion attacks. Corrosion Experts

Polyurethane coatings were first used in 1972.[citation needed] In comparison with other coatings, the internal polyurethane lining exhibits a high resistance to various different media such as drinking water, wastewater, de-mineralised water, industrial water and gas, as well as to aggressive solutions such as sulphuric acid. The polyurethane outside coating is suitable for all kinds of soil.

Polyurethane is a thermosetting plastic with no solvents, with a three-dimensionally linked molecular structure giving it mechanical stability. The polyurethane used for conating has the following standard properties, according to EN 545 and ISO 2531 standards.

Q:Can ductile iron pipes be used in contaminated groundwater systems?: Yes, ductile iron pipes can be used in contaminated groundwater systems. Ductile iron pipes are known for their corrosion resistance, making them suitable for handling water with various levels of contamination. Additionally, their strength and durability allow them to withstand the harsh conditions of contaminated groundwater systems.

Q:Can ductile iron pipes be used in areas with high soil liquefaction potential?: Ductile iron pipes can be used in areas with high soil liquefaction potential, but certain precautions and considerations need to be taken into account. Soil liquefaction is a phenomenon in which saturated soil temporarily loses its strength and behaves like a liquid during an earthquake or other seismic events. Ductile iron pipes are known for their strength, durability, and resistance to external loads, making them suitable for various applications, including water and wastewater transportation. However, when it comes to areas with high soil liquefaction potential, additional measures should be considered to ensure the pipes' performance and integrity. One crucial factor to consider is the pipe's installation depth. Ductile iron pipes should be installed at a sufficient depth below the ground surface to minimize the effects of soil liquefaction. The depth will vary depending on soil conditions and the level of seismic activity in the area. Consulting with geotechnical engineers and following local building codes and regulations is essential to determine the appropriate installation depth. Furthermore, proper backfill materials and compaction techniques must be employed during the pipe installation process. Using granular materials, such as crushed stone or gravel, for backfill can help improve the soil's stability and reduce the potential for liquefaction. Adequate compaction of the backfill is also necessary to ensure the pipes' stability and prevent settlement or movement during seismic events. Moreover, it is recommended to use flexible joints, such as restrained joints or push-on joints, when installing ductile iron pipes in areas prone to soil liquefaction. These joints allow for some movement and flexibility, which can help absorb the ground's movement during an earthquake, reducing the stress on the pipes and minimizing the risk of damage. Regular inspection and maintenance of the ductile iron pipes are crucial in high soil liquefaction potential areas. Monitoring for any signs of movement, settling, or damage should be conducted, and any necessary repairs or reinforcements should be promptly addressed to ensure the pipes' continued performance and safety. In conclusion, ductile iron pipes can be used in areas with high soil liquefaction potential, but careful consideration of installation depth, proper backfill materials and compaction, the use of flexible joints, and regular maintenance are crucial to ensuring their optimal performance and longevity. Consulting with geotechnical engineers and following local building codes and regulations is highly recommended to ensure the pipes' suitability in such areas.
