Is Ductile Iron expensive?
Ductile iron is slightly more expensive than gray iron but is cheaper and easier to cast than steel. It is usually chosen for its mechanical properties and value. As a less brittle alloy than cast iron, it is used in applications where ductility and impact resistance is useful.
What is the price of cast iron pipe?
($8.80 /ft.)
What is the life expectancy of ductile iron pipe?
100 years
This kind of pipe has been used for water or sewer conveyance since the 1950’s, and based on studies of this pipe from the 50’s, it is believed that ductile iron pipe will last at least 100 years which is at least as good as cast iron, but with more reliability.
Is ductile iron pipe more expensive than PVC?
PVC pipe’s longevity depends on stress and time—the greater the stress, the sooner it will fail. Ductile iron’s strength is not compromised over time. The cost to pump water through PVC pipe is as much as 38% more expensive than that of Ductile iron pipe, increasing life cycle costs and releasing more greenhouse gases.
Which is more expensive cast iron or ductile iron?
Ductile iron has excellent corrosion resistance, tensile strength, and yield strength. Ductile iron is a strong and reliable material for pipes, fittings, and valves. One drawback is price. Ductile iron is typically more expensive than cast iron due to its more complicated chemical makeup.
What is the OD of 6 cast iron pipe?
Service Cast Iron
| Size (in) | Inside Diameter of Hub (in) | Outside Diameter of Barrel (in) |
|---|---|---|
| 5 | 5.94 | 5.30 |
| 6 | 6.94 | 6.30 |
| 8 | 9.25 | 8.38 |
| 10 | 11.38 | 10.50 |
Does Ductile iron pipe need cathodic protection?
Cathodic protection is recommend for use on Ductile iron pipe in only the most extreme corrosive environments. As a result, the Ductile iron joints require bonding to allow electrical current to flow along the pipeline.
