What is the typical lifespan of ductile iron pipes used in water distribution?

Ductile iron pipes are commonly utilized in water distribution systems due to their strength, durability, and resistance to corrosion. The typical lifespan of these pipes is usually projected to be in the range of 50 to 100 years.

Several factors contribute to this longevity, including the material's inherent properties, the quality of manufacturing, and the environmental conditions in which the pipes are installed. Ductile iron is designed to withstand high pressure and is also less susceptible to cracking than traditional cast iron, enabling it to better handle the stress that comes from water flow and shifting soil conditions.

Additionally, many modern coatings and linings applied to ductile iron pipes further enhance their durability and resistance to corrosion, which can significantly extend their usable life. Therefore, when considering the lifespan of ductile iron pipes in a water distribution system, the estimate of 50 to 100 years accurately reflects their long-term performance in practical applications.
