Ductile Iron Pipe

Natural and/or manmade ground movements, is the main reason for water supply damages. Materials used in the production of pipes and fittings, have to be ductile, flexible and resistant to impacts in order to minimize the effect of these movements on networks.

Water distribution lines are high-cost investments. Therefore, features like life cycle cost, durability, low operation expenses, ease of assembling, maintenance and repair expenses ought to be considered as well as material unit price in the project designing and feasibility stages.

Ductile iron casting adds on tensile strength, impact resistance, and elongation abilities to the superior properties of metal casting which are high resistance to corrosion and abrasion, ease of machinability and fatigue strength.

 

Features:

  • Facilitating high resistance to loadings, pressure and vacuum with high tensile strength,
  • Enabling high resistance to corrosion,
  • Not requiring cathodic protection,
  • Less operating cost since cast pipes have larger nominal diameter than polyethylene pipes.
  • Being the best pipe in case of an earthquake, with its ability of resilience and resistance to impacts without deformation,
  • Long product life, exceeding 100 years,
  • Preserving the quality of water with healthy interior coating.
