Ductile Iron retains the corrosion resistance of cast iron but has more than double tensile strength. The main differences between Ductile and Cast Iron lie in the shape of the graphite in the microstructure of the metal. In Cast Iron, the graphite is present in plate-like flakes, which makes cast iron brittle but in the case of ductile iron, the shape of the graphite becomes spheroidal nodule, which increases tensile strength and makes Ductile Iron sturdy and shock-proof.

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 pipe is considered as the most preferred pipe material for water supply and pressure sewerage application all over the world. Higher tensile strength and diametral stiffness than mild steel is offered by it and retains the inherent corrosion resistance of cast iron. Ductile Iron pipes provide substantial benefits in terms of pressure bearing ability, impact resistance and capacity to sustain external static/dynamic loading.

Benefits –

  • Requires very little maintenance
  • The service life of around 100 years
  • Having as much as 98% recycled content
  • Lower costs from increased flow capacity lead to significant energy savings
  • Strong enough to withstand the most severe conditions
  • Resistant to corrosion in most soils, and typically requires only effective, economical polyethylene encasement
  • Provides protection against surges and increased pressure loadings over the years
  • Ductile Iron Pipe is rugged and resists damage during handling and installation
  • Easy to install

HDPE or high-density polyethylene pipes are specially manufactured electrical conduits which are made from graded raw materials like PE 63, PE 80 and PE 100. They are the most suitable replacement for CI pipes and GI pipes and are one of the most premier mediums of conveying and transporting – gases, portable water, chemicals, telecommunication, and electrical ducting, drip irrigation systems, sprinkler systems.

Advantages –

  • These conduits are as much as 6 to 8 times lighter than the CI popes and the GI pipes.
  • Exceptionally easy to carry which saves upon the transportation costs and also helps keep the handling costs at a lower level.
  • They are non-corrosive which makes them appropriately suitable for the purpose of water transportation.
  • They have a smoothed out inner surface that hinders the growth of bacteria and microorganisms of any kind.
