Why Ductile Iron Pipe is Best for Water and Wastewater


Ductile iron pipe is graphite-rich cast iron with a spheroidal graphite molecular structure created from ductile cast iron. Cast iron with this molecular structure is less brittle and more impact resistant than other kinds with a flaky structure. In trenchless technology, the ductile iron pipe is utilized for water and sewer lines. If non-corrosive linings such as cement, asphalt, paint, or polyethylene encasement are used inside and out, ductile iron pipes can last more than 100 years

The ductile iron pipe has been acknowledged as the industry standard for contemporary water and wastewater systems since its introduction in 1955. Its strength, durability, and reliability for delivering raw and potable water, sewage, slurries, and process chemicals have been demonstrated over five decades in the field. During transportation and handling, the ductile iron pipe is resistant to damage. It can survive the harshest operating circumstances, such as water hammers, frozen ground, deep trenches, high water tables, heavy traffic, rocky trenches, and places with shifting, expanding, and unstable soils, once installed.

The advantages of ductile iron pipe

With a service life of over 100 years, a ductile iron pipe is tough, safe, and dependable. Because of its long service life, resistance, energy savings while in service, recycled content, and recyclability, it is an environmentally superior pipe. Ductile iron pipe is an important part of a sustainable energy future as well as a contemporary, dependable water infrastructure. A ductile iron pipe has stood the test of time, is manufactured in India, and supports Indian jobs in towns around the country.

- Environmentally Superior Pipe

Ductile iron pipes are environmentally friendly, safe, and long-lasting. Ductile iron pipes are made up of at least 90% recycled materials, and the pipes themselves are 100% recyclable.

- Better Value

Since it lasts longer and saves money over time, the ductile iron pipe is a better bargain than plastic pipe. According to a University of Michigan study, the ductile iron pipe is a cheaper material over the life of a pipeline because it has a lesser cost of operation and maintenance with lower energy costs.

- Lower Emissions and Energy Consumption

Due to decreased greenhouse gas emissions in both the production and operation phases, the ductile iron pipe has a better environmental performance. Ductile iron pipe is beneficial to the environment from start to finish since it consumes less energy to pump water and has a reduced environmental impact

- Resilient

Extreme weather, natural calamities, soil pollution, and unanticipated scenarios are no match for ductile iron pipes. Ductile iron is the pipe of choice for protecting against wildfires, earthquakes, floods, storms, severe temperatures, and the frequent, ongoing stressors that water utility systems face due to their strength and endurance. Because it is durable and saves cost over time, the ductile iron pipe is a better bargain than plastic pipe. According to a University of Michigan study, the ductile iron pipe is the more cost-effective material during the life of a pipeline since it has lower operational and maintenance costs as well as reduced energy expenditures.

- Safety and Health

Ductile iron pipe manufacturing does not produce hazardous compounds such as vinyl chloride, dioxin, or ethylene dichloride. Ductile iron pipe, unlike plastic pipe, does not absorb contaminants and provides better protection against pollution of drinking water. Plastic pipe is more prone to catastrophic installation and operational failures, resulting in worker casualties and property damage. Ductile iron pipe is safer to install and maintain.

- Longer Cycle of Life

Ductile iron pipe requires little maintenance and is predicted to last for at least 100 years. When compared to plastic pipe, which has a 55-year average service life, ductile iron pipe offers considerable cost savings and benefits. It’s a product with a longer life cycle that saves cost while also being beneficial to the environment. This means that in local communities, there are fewer interruptions, fewer replacements, and more peace of mind.

Ductile iron pipe specifications

The European Standard EN 545:2010 specifies that ductile iron pipes must be centrifugally cast. Depending on the pipe class, centrifugally cast pipes must undergo a work hydrostatic test for at least 10 seconds at a required pressure specified in EN 545:2010 Standard. Pipes, pipe-fittings, and joints must be able to withstand normal working conditions, including internal pressure, external strains, overloads, and reactions from soil or supports, as determined by the contractor depending on the final design for each segment, taking into account the surge and test pressures. The producer must produce the pipes by the following specifications unless otherwise indicated in the specification:
