V Duke Di Pipes

V-DUCPIPE - Superior Quality DI Pipes.

DI pipes are made from ductile iron, known for its high tensile strength, and are widely used for water supply and pressure sewerage applications. The V-Ducpipe ensures good health flows to every home since it is inherently corrosion resistant. It available in classes K7 and K9 with diameter DN 100 to DN 1200, conforming to IS 8329:2000 standards. This guarantees more pressure bearing ability, unmatched impact resistance and improves the capacity to sustain static or dynamic loading.


  • Withstands very high pressure as well as static and dynamic load
  • High tensile strength and impact resistance
  • Effective leak-tight joint through push-on type joints
  • Higher resistance to corrosion due to higher presence of carbon in microstructure and outer surface coated with zinc


  • Water Distribution Di Pipes

    Water distribution networks.
