Overview of Ductile Iron Pipe
Ductile cast iron, also called ductile iron, spheroidal graphite iron, or nodular cast iron, is a type of cast iron invented in 1943. While most varieties of cast iron are brittle, ductile cast iron is much more flexible and elastic, due to its nodular graphite inclusions.
Graphite particles exist in the form of sphericity in ductile cast iron. Sizes graphite particle are restricted to 6 -7 class and spheroidizing rate should not be less than 80%. Thus after the spheroidizing process, ductile iron will be endowed with mechanical properties of both cast iron and steel.
Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water supply and sewerage design. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.

Self-restrained Joint
Self-restrained Type is a push-in self anchored joint. The principle of joint anchoring consists in transmitting the axial forces from one pipeline to the following one, thus ensuring that the joint does not come apart.
The application of self-restrained joints is of particular interest where congested conditions preclude concrete anchor block constructions or in poorly cohesive soils.Self-restrained joints combine the advantages of flexible joint pipes and welded joint pipes.

This strength empowers the pipe to resist the effects of ground movement, such as soil settlement, subsidence, or shifting caused by seismic activity. Furthermore, ductile iron pipe possesses inherent flexibility, allowing it to absorb and distribute stress resulting from ground movement. The pipe's flexibility helps reduce the impact of settlement by enabling it to adapt and adjust to changes in the surrounding soil. This characteristic helps prevent the pipe from developing cracks, fractures, or leaks when the ground shifts or settles. Moreover, ductile iron pipes are frequently installed with flexible joints, such as push-on or mechanical joints, which further enhance their ability to accommodate ground movement. These joints provide a level of flexibility and movement, enabling the pipe to adapt to soil changes without experiencing concentrated stress or structural failure. Additionally, ductile iron pipe exhibits high resistance to corrosion, which is another crucial factor in its capacity to handle ground movement and settlement. Corrosion can weaken pipes and make them more vulnerable to damage during ground shifts. However, the corrosion-resistant properties of ductile iron help maintain the pipe's structural integrity and durability, even in challenging soil conditions. In conclusion, ductile iron pipe is ideally suited for handling ground movement and settlement due to its impressive tensile strength, flexibility, and corrosion resistance. These qualities enable the pipe to endure external forces and adapt to changes in the surrounding soil, minimizing the risk of damage, leaks, or failure.
- Q: Can ductile iron pipes be used for pressure surge applications?
- Yes, ductile iron pipes can be used for pressure surge applications. Ductile iron pipes have excellent strength and durability, making them suitable for handling surge pressures caused by sudden changes in flow rates or water hammer events. They can withstand high internal pressures and have a high resistance to impact and fatigue. Additionally, ductile iron pipes have a smooth interior surface that allows for efficient flow of fluids, minimizing the potential for pressure surges. However, it is important to consider factors such as pipe size, wall thickness, and proper installation techniques to ensure the pipes can safely handle the specific pressure surge conditions in a given application. Consulting with a professional engineer or pipe manufacturer is recommended to determine the suitability of ductile iron pipes for pressure surge applications.
