Ductile Iron Pipes
Ductile iron tubes or pipes, also known as ductile iron pipes (DIP), are a type of pipe made from ductile cast iron, a type of cast iron that is more flexible and durable than traditional cast iron. Here is an introduction to ductile iron tubes/pipes
Material: Ductile iron pipes are made of ductile cast iron, which is a type of cast iron with graphite nodules in its microstructure, providing enhanced strength and ductility.
Strength: Ductile iron pipes have high tensile strength and are capable of withstanding high pressures, making them suitable for various applications.
Corrosion Resistance: These pipes offer excellent corrosion resistance, especially when coated with protective materials such as zinc, bitumen, or epoxy.
Ductility: Ductile iron pipes have good ductility, allowing them to bend and deform without breaking, which is beneficial in areas with ground movement or seismic activity.
We are sure that you can always select one type that meet you best.

Strength and Durability: Ductile iron pipes are known for their high strength and durability, making them suitable for various applications, including water and sewage systems, gas pipelines, and industrial piping.
Flexibility: Unlike traditional cast iron, ductile iron is more flexible and less brittle, allowing it to withstand bending and shifting without cracking.
Corrosion Resistance: Ductile iron pipes have good corrosion resistance, which is crucial for long-term use in water and sewage systems where exposure to moisture and chemicals is common.
Smooth Interior: The smooth interior surface of ductile iron pipes reduces friction and allows for efficient flow of fluids, minimizing pressure drop and energy loss.
Jointing Methods: Ductile iron pipes can be joined using various methods, including push-on joints, mechanical joints, flanged joints, and welding, offering flexibility in installation.
Long Service Life: Properly installed and maintained, ductile iron pipes can have a service life of 50 years or more, providing a reliable and long-lasting solution for fluid transportation.
