Benefits of Ductile Iron Pipes in Water Infrastructure: Durability and Longevity
Water distribution systems and wastewater pipelines are required for all residences, establishments, and business units. Understanding the qualities and benefits of different DI water piping materials is vital to ensuring that such significant piping networks function as desired. Pipelines for water and sewage can be built with a variety of materials, including vitrified clay, steel, concrete, ductile iron, and polymers. DI pipes in water infrastructure are essential components of a sustainable energy future that are durable and modern. A ductile iron pipe has lasted through the test of time around the globe with its pipe durability and efficiency.
What is Ductile Iron?
Ductile iron is an upgrade for cast iron. Ductile iron is made from scrap iron or steel. The primary ingredient used to make it is crude iron, which is created by smelting ore in the blast furnace. It's commonly referred to as "pig iron." About 90% of iron having a high carbon content is ductile iron. It has highly stable chemical characteristics.
Chemical makeup: The ASTM standard for ductile iron casting states that the ductile iron is 2.25–3% silicon and 3.5–3.9% carbon, with trace amounts of manganese, magnesium, sulphur, phosphorus, and other elements.
Production: Ductile iron casting is a method of adding magnesium/cerium (as an alloy of magnesium/cerium) to cast iron. It modifies how graphite is created by interacting with the oxygen and sulphur in the molten iron.
Form: Ductile iron (also known as spheroidal graphite cast iron or nodular cast iron) has mainly substituted high-grade cast iron as the primary industrial resource. The presence of nodular graphite in ductile iron castings makes them far more ductile than other types of cast iron, which are generally a little brittle. Solidified ductile iron castings comprise almost ideal spheres of graphite. The alloy form of ductile iron is less uneven due to the trace amounts of cerium or magnesium added to the graphite.
Benefits of Ductile Iron or DI Pipes in Water Infrastructure
The benefits of using ductile iron pipes in water infrastructure are as follows:
Easy Installation
Compared to other pipe materials, ductile iron is a less expensive water piping material and requires less effort to install because of its flexibility and durability. Due to their durability and adaptability, ductile iron pipes can be laid with less severe bedding and backfill requirements.
To reduce settlement and long-term creep, other pipe materials such as PVC, concrete, and clay need to meet precise engineering fill and bedding parameters. Steel pipes are ductile as well; however, during installation, they could also require extra braces and exterior soil support. Furthermore, because DI pipes are machineable, cutting, drilling, and direct tapping may be done on them with ease in the field.
Tensile Strength
Ductile iron provides enhanced durability and resistance. The graphite in ductile iron takes on a nodule or spheroidal form. This happens through adding an inoculant (often magnesium) into the molten iron during the manufacturing process. The strength of ductile iron is nearly twice that of cast iron as a result of this new graphite structure. Furthermore, ductile iron is far more resilient than cast iron to extension and compression.
Longer Life-Span
A DI pipe has a projected life expectancy of a minimum of 100 years and requires minimal upkeep. When considering the advantages and cost reductions over plastic pipe—which has an average lifespan of 55 years—ductile iron pipe shines. Longer life cycles are more environmentally friendly and cost-effective. Additionally, it results in fewer replacements, fewer difficulties, and increased overall peace of mind.
Environment Friendly
Ductile iron pipes are eco-friendly and recyclable. Iron recovered from recycled steel scraps, destroyed structures, or various other sources can be used to create them. They generate no net waste because the pipes are fully recyclable as well. In the end, its recyclability lowers carbon dioxide emissions and environmental contamination. Not only does this help the environment by guaranteeing appropriate waste management, but it also makes it easier to distribute and dispose of wastewater and water, respectively.
Health and Safety
No hazardous compounds, such as vinyl chloride, dioxin, or ethylene dichloride, are released during the making of ductile iron pipes. Compared to plastic pipe, a ductile iron pipe is incapable of absorbing contaminants and offers superior defence against tainted drinking water. Compared to plastic pipe, which is more likely to have adverse installation and operational issues that result in worker injuries and damage to property, ductile iron pipe is easier to put in and maintain.

Comparing Strength and Performance of DI Pipes vs Other Pipes
Not all pipe performance is the same, basically due to their manufacturing materials. When deciding which kind of pipe is appropriate for a particular project, there are a number of variables for design engineers to take into account. These variables include project requirements, system startup cost, maintenance charges, dependability, and performance over time. To get the best pipe performance, it is necessary to use the right pipe material for any project. Today, Ductile Iron pipes stand out among the available options. Understanding the differences between DI pipes and other pipes can help engineers in choosing the ideal material for their respective projects.
Pipe Material Comparison: Performance of Ductile Iron and Other Pipes
There are several kinds of pipes available for various applications. Having a pipe material comparison between the different pipes and ductile iron pipes will make every engineer's work easier.
Ductile Iron Pipes and Galvanised Iron Pipes: DI vs GI pipes
Ductile Iron Pipes:
- DI pipes are a combination of silicon, carbon, and ductile iron. A melted mixture is shaped like a cylinder and chilled.
- Due to their great tensile strength, ductile iron pipes are resilient to collisions, vibrations, and large loads, among other external factors.
- Ductile iron pipes are simple to install and manage since they are connected via a variety of modes, such as push-on flexible joints, mechanical joints, and flanged joints.
Galvanised Iron Pipes:
- Steel is used to make galvanised iron pipes. A zinc covering protects the pipes from rust and corrosion.
- Galvanised iron pipes are durable but ductile, which makes them more vulnerable to breaking and bursting under strain.
- The setting up of galvanised iron pipes calls for certain equipment and techniques, which can be costly and tedious. They additionally need routine maintenance to avoid corrosion and rust.
Ductile iron pipes are often more costly than galvanised pipes due to their increased strength, longevity, and dependability. But because they last longer and need less upkeep and repair, they offer a long-term, affordable solution. Although galvanised iron pipes can be less costly at first, their rust and corrosion risk, as well as their shorter lifespan, can make them more expensive over time.
Ductile Iron Pipes and Steel Pipes
Ductile Iron Pipes:
- A ductile iron pipe has a polyethylene encasement to reduce the risk of corrosion in harsh conditions.
- Ductile iron pipes have a substantially greater carbon content, ranging between 3 and 3.9%. The increased carbon content increases the strength, stress resistance, and resistance to natural disasters of ductile iron pipes.
- The ductile iron pipe is capable of being rerouted using its push-on joints. The installers have greater flexibility because of this feature. Regardless of the weather or temperature, they are simple to install.
Steel Iron Pipes:
- Steel pipe needs a bonded coating (usually a tape-wrap or cement-mortar coating) in order to be resistant to corrosion. The steel pipe industry recommends different kinds of corrosion control depending on the manufacturer and market conditions.
- Usually, the carbon content of steel is less than 0.4%. It is feasible to contain up to 2% carbon, though.
- Steel pipes must be welded together before being installed. Unfavourable weather can cause the installation to stop.
Ductile iron pipe offers a more affordable transmission line than steel iron pipe because of its bigger interior diameter.
Ductile Iron Pipe vs. PVC Pipes
The difference between ductile iron and PVC pipes are:
- Ductile iron pipe offers more than 13 times the impact strength, nine times the tensile strength, and four times the burst strength of PVC pipe.
- Ductile iron pipe is resilient under stress. PVC fails eventually under stress. The more stress it experiences, the faster it will fail.
- Petrochemicals are used to make PVC pipes, a procedure that may be bad for the environment and people's health. Recycled steel and iron are used to make ductile iron pipes.
- Temperature variations have little effect on ductile iron pipes. PVC pipe weakens in hotter climates and becomes brittle in cooler ones.
Ductile Iron Pipe vs. HDPE Pipes
The comparison between ductile iron and HDPE pipes:
- HDPE is manufactured from ethylene, which is obtained from petroleum and natural gas.
- On the other hand, the ductile iron pipe is made from iron scrap metal that usually has more than 98 per cent recycled material in it.
- In comparison to HDPE, DI pipe has a hydrostatic design base that is 26 times larger.
- HDPE connectors are butt-fusion welded together, whereas DI pipe relies on a push-on rubber gasket joint that is simple to construct and disassemble.
- Ductile iron has greater than 24 times the tensile strength of HDPE pipe.
