Ductile Iron is a very strong, safe, and reliable product and has stood the test of time. Modern Ductile Iron Pipe is made to last over 100 years and it is an environmentally preferable product due to its recycled content, energy savings while in service, its durability, its own recyclability and because of the commitment of the DI Pipe industry.

Ductile Iron is also known as the spheroidal graphite iron or nodular cast iron was invented in 1949. Ductile Iron retains the corrosion resistance of cast iron but has more than double the tensile strength, Cast Iron has 180 MPa (min), and Ductile Iron has 420 Mpa (min). The crucial differences between Ductile and Cast Iron lie in the shape of the graphite in the microstructure of the metal. Graphite is present in plate-like flakes in Cast Iron which makes it very brittle. In ductile iron, the shape of the graphite becomes a spheroidal nodule, which increases tensile strength and makes Ductile Iron sturdy and shock-proof. Ductile Iron pipe is considered as the most preferred pipe material for water supply and pressure sewerage application all over the world. It offers higher tensile strength and diametral stiffness than Mild Steel and retains the inherent corrosion resistance of cast iron. Pipes made Ductile Cast Iron, provides substantial benefits in terms of pressure bearing ability, impact resistance and capacity to sustain external static/dynamic loading.

It’s benefits –

  • It requires very little maintenance once it’s installed and is designed to last at least 100 years.
  • It has been reported that Ductile Iron Pipe has the longest service life among all the material in the market today.
  • Made with around 98% recycled material, Ductile Iron Pipe itself is a 100% recyclable material.
  • Lower costs from increased flow capacity lead to significant energy savings during the pipe’s lifetime in service. Ductile Iron saves money.
  • It is extremely strong to withstand the most severe conditions, from high-pressure applications to heavy earth and traffic loads, to unstable soil conditions.
  • It is resistant to corrosion in most soils and typically requires only effective, economical polyethylene encasement, like a loose sheathing.
  • For its strength, durability, and conservative design, Ductile Iron is the pipe of choice to protect against surges and increased pressure loadings.
  • Installation is easy and safe for workers as they can cut and tap Ductile Iron Pipe on site.
  • The pipes are rugged and resist damage during handling and installation.
  • The metallic nature of Ductile Iron Pipe means the pipe can be easily located underground with conventional pipe locators.
