TENSILE STRENGTH: ≥ 420 N/mm2
ELONGATION (%): (DN ≤ 1000) ≥ 10; (DN > 1000) ≥ 7
HARDNESS (HB): ≤ 230
Duct Iron Steel has high corrosion resistance
Duct iron steel has better corrosion resistance than Steel pipe and Gray cast iron pipe.
Resistance to cathodic corrosion
DCI pipe doesn’t need cathodic protection, whereas steel pipe does. Because DCI pipes are sealed by means of a rubber gasket, they are insulated from each other with no continuity to current flow.
Duct Iron Steel has high flow capacities
The internal diameter of Ductile Iron Pipe is larger than that of any other pipe material for a given pipeline diameter. This, combined with the smooth mortar lining implies that Ductile Iron Pipe provides the least resistance to flow, ensuring a lower cost in power consumption across the life cycle of the system for equivalent flow when compared to other pipe materials.
Ductile Iron Pipe is strong, tough and forgiving, making it the most maintenance-free pipe material
- Resistance to vandalism
- No unauthorized connections
- Resistance to second corner damage
- Can be installed at greater depth of cover
- Simple inexpensive bedding and back filling
- Can be installed at shallow depth with high traffic loading
- Capability to cope with poor load bearing or unstable ground
- Suitable for narrow trenching as pipe is not reliant on side fill support
- High beam strength allows pipe to cope with uneven longitudinal loading
