Water and wastewater pipelines are essential for households, industries, and businesses. Choosing the right pipe materials is crucial for ensuring that these pipelines perform effectively. Ductile iron pipes are one of the best options for such infrastructure projects, offering a range of benefits. In this blog, we’ll explain why ductile iron pipes are the ideal choice for water and wastewater pipelines.
Water pipelines are designed to deliver treated drinking water to consumers. These systems include large-diameter main pipes that supply entire cities, as well as smaller branch lines serving specific buildings or streets. On the other hand, wastewater pipelines are used to carry used water from homes and workplaces. Wastewater is drained into a sewer pipe when you flush a toilet, pull the plug from a sink, or take a shower. These pipes are buried underground and sealed to prevent leaks.
Ductile iron pipes offer excellent advantages that make them ideal for water and wastewater pipelines. They are known for their strength, durability, and flexibility. The material also has a high strength-to-weight ratio, which makes it easier to handle and install compared to other piping methods.
Ductile iron pipes are highly machinable, meaning they can be easily cut or bent without breaking or chipping. The graphite and silicon content in ductile iron helps provide lubrication, flexibility, and abrasion resistance during the manufacturing process. This results in higher productivity, longer tool life, faster production speeds, and lower costs for water and wastewater pipeline projects.
One of the most significant advantages of ductile iron pipes is their superior resistance to corrosion. Compared to regular cast iron pipes, ductile iron pipes are far more durable and resistant to environmental factors. Ductile iron pipes are manufactured using strict casting requirements, advanced metallurgical processes, and rigorous quality control, ensuring their long-lasting performance in water and wastewater pipelines.
Ductile iron pipes are incredibly durable, designed to meet demanding operational conditions. They feature a minimum elongation requirement of 10%, a yield strength of 42,000 psi, and tensile strength of 60,000 psi. This ensures they can withstand challenging conditions such as unstable soils, river crossings, and traffic loads, making them an excellent choice for water and wastewater pipeline systems.
Ductile iron pipes are made primarily from recycled steel and other metals, with up to 95% of their content being recycled. They are also fully recyclable, contributing to a more sustainable infrastructure. Additionally, using ductile iron pipes can reduce energy consumption by up to 38%, resulting in a lower carbon footprint. The use of ductile iron pipes also helps prevent the leakage of toxic chemicals into public drinking water, ensuring the safety and health of the environment and communities.
Due to the exceptional durability of ductile iron pipes, they require minimal maintenance over their lifespan. In case of a water leak, pipe sleeves can be used to repair the pipes, preventing the need for costly replacements. This low-maintenance feature makes ductile iron pipes a cost-effective solution for water and wastewater pipelines.
