The cast iron pipe was installed in 1455 in Siegerland, which had good strength, and long life. The ductile iron pipe (DI Pipe) is an upgraded version of the grey cast iron pipe, which was produced experimentally in 1948 and first used in 1960 (in India 1994). DI Pipe has superseded cast-iron pipe. DI Pipe is differentiated by the spheroidal or nodular nature of the graphite within the iron. It is mostly used for drinking water transmission and distribution. Today’s modern iron pipe is made to last more than 100 years. There are some important facts about Jai Balaji Group ductile iron pipe (DI Pipe) that make it the preferred industry standard for water systems.


  1. Internal and External Coating:
  • Internal Lining Coating:-

Jai Balaji Group ductile iron pipe (DI Pipe) is lined with cement mortar, a combination of cement, sand, and water, to increase strength and prevent corrosion.

  • External Coating: –

Jai Balaji Group ductile iron pipe (DI Pipe) is externally coated with metallic zinc of at least 99.99% purity by mass and follows ISO8179 standards. When this metallic zinc comes into contact with the surrounding soil, it transforms into zinc salts and acts as a protective barrier.

  1. Field Training and Assurance Measures:

Our team of highly trained professionals verifies and test DI pipe installations before installing them to ensure efficient and safe fitting.

  1. Durability:

Our centrifugal casting process, LPS polyethylene encasement and using evolved laying practices prolong the lifespan of the ductile iron pipe (DI Pipe) to as long as 100 years.

  1. Corrosion Resistance:

Coastal and marine environments are highly corrosive environments that can harm the health of a naked, DI pipe. To protect the pipe from corrosion and to increase its lifespan, we use black bitumen, blue epoxy as well as red epoxy coating.

  1. Cutting:

Jai Balaji Group uses two different cutting methods- manual as well as power-driven abrasive cutting- to ensure that the DI pipes are best suited to your needs.

  1. Edge Preparation:

Chamfering is an essential part of the process as it facilitates the assembly of joints and prevents leakage through damage in the rubber gasket. Our ductile iron pipe supersedes the standards of chamfering and ensures leak-proof pipes.

  1. Environmental Benefits:

Our ductile iron pipe (DI Pipe) also has the following environmental advantages:

  • Energy-saving due to less friction
  • Prevents leaching of toxic chemicals into the water
  • Recycles steel and scrap metal as raw materials which contribute to 20-25% of the total
  • Pipes are 30% recyclable even after decades of usage
  1. Additional Strength:
  • Strongest pipe – high tensile and bear strength.
  • High ring stiffness- takes care of high soil and traffic load.
  • Withstands severe crushing load and high impact load.
  • Can endure high working pressure.
  • Hydro testings ensure safety against surges
  • Speedy laying/installation because of push-on type joints
  • Lightweight yet resilient – easier to handle.
  • Enables welding

How many times in your life do you make a choice that others must live with for more than a century? Very few indeed.

Selecting the pipes you install has financial as well as environmental consequences. One size does not fit all conditions, and we as manufacturers consider all conditions of today to ensure you choose the best fit for tomorrow. Choose Jai Balaji Group DI Pipe for safer water transmission.
