Ductile iron pipes

Advantages of Ductile Iron Pipes

- Inherent resistance of ductile iron adainst corrosionalong with improvement of this resistance via various coatings

- Appropriate resistance againts pressures such as water hammer and external pressure like traffic loads and etc.

-Suitable for use in loose ground with high level of subterranean water

- Resistance against electrical currents due to use of rubber gasket at the joint points

- Adequate resistance against damages caused by displacement and transportation

- Flexibility and adaquate resistance against landslide,on faults and earthquake-prone region

- Great potential for cuttuing and reaming

- Appropriate for mountainous areas due to lack of need for especial bedding and precise considferation of soil compaction and trench depth

- High working pressures comparing to other types of pipe

- Low-pressure drop as a result of lower pumping cost due to larger actual inside diameters and C coefficient of the pipes

- 100 years of lifetime
