5.FAQ:
We have organized several common questions for our clients，may help you sincerely：
1.Q: Why would you choose ductile iron pipe rather than other pipe materials?
A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.
2.Q:Why can you guarantee the inner of pipes can’t be corroded?
A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.
- Q: What is the expected buoyancy of ductile iron pipes?
- Several factors, including diameter, wall thickness, and fluid specific gravity, can influence the expected buoyancy of ductile iron pipes. However, in general, ductile iron pipes are recognized for their relatively low buoyancy compared to materials like plastic or concrete. Ductile iron pipes possess a higher density and weight, resulting in a greater resistance to buoyancy forces. This quality makes them suitable for applications where buoyancy is a concern, such as water and wastewater transmission systems. Their inherent strength and weight combination ensures that the pipes stay grounded and do not float or rise to the surface. It is important to acknowledge that despite the lower buoyancy of ductile iron pipes compared to other materials, there may still be some level of buoyancy in certain scenarios, particularly when the fluid being transported has a lower specific gravity. To address this potential issue, measures like anchoring or ballasting can be employed to guarantee the stability and integrity of the pipeline system. In conclusion, while the expected buoyancy of ductile iron pipes is generally low, it is crucial to consider the specific conditions and requirements of the project to determine the most suitable pipe material and design for optimal performance and safety.
- Q: How do ductile iron pipes handle ground movement near rivers and lakes?
- Ductile iron pipes are well-suited to handle ground movement near rivers and lakes due to their unique properties and construction. These pipes are made from a type of cast iron that is known for its high strength and flexibility, making them highly resistant to ground movement and other external forces. One of the key features of ductile iron pipes is their ability to withstand bending and stretching without breaking. This flexibility allows the pipes to adapt to ground movements, whether they are caused by natural factors like soil settling, erosion, or even seismic activity. The pipes can absorb and distribute the stress caused by ground movement, reducing the risk of cracks or fractures. Additionally, ductile iron pipes have a high impact resistance, which means they can withstand external forces such as pressure from shifting soil or heavy equipment. This makes them less susceptible to damage during ground movements near rivers and lakes where erosion or flooding can occur. Furthermore, ductile iron pipes have a smooth internal surface, which reduces friction and resistance to flow. This ensures efficient water transportation even in areas with ground movement, preventing any potential blockages or disruptions to the water supply system. To enhance their resistance to ground movement, ductile iron pipes are often installed using flexible joints, such as restrained joints or push-on joints, depending on the specific project requirements. These joints allow the pipes to move slightly without causing damage to the overall system, providing additional protection against ground movement near rivers and lakes. In summary, ductile iron pipes are highly capable of handling ground movement near rivers and lakes due to their strength, flexibility, impact resistance, and smooth internal surface. These qualities make them a reliable choice for water transportation systems in areas prone to ground movement, ensuring a durable and efficient infrastructure for the supply of water.
- Q: Does the cast iron pipe need separate corrosion protection?
- No, the inner and outer corrosion protection of the tube has been done.

Additionally, ductile iron pipes have a longer lifespan, reducing the need for frequent maintenance or replacement. Therefore, they are a reliable choice for irrigating golf courses, where a consistent and efficient water supply is crucial for maintaining healthy turf and landscaping.
- Q: Can ductile iron pipes be used in areas with high water velocity?
- Yes, ductile iron pipes can generally be used in areas with high water velocity. Ductile iron is known for its strength and durability, making it suitable for various applications, including high-velocity water flow. However, it is important to consider factors like pipe size, wall thickness, and proper installation techniques to ensure the pipes can handle the specific velocity conditions effectively.
- Q: Advantages and disadvantages of ductile iron pipes?
- Ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanisms; cast iron pipes; main use; municipal high water drainage.
- Q: How do ductile iron pipes handle pipe deflection?
- Ductile iron pipes possess exceptional strength and flexibility, enabling them to effectively handle pipe deflection. Pipe deflection, referring to the bending or curving of a pipe from its original straight alignment, is easily managed by ductile iron pipes. When external forces such as soil movement or heavy loads are applied, ductile iron pipes possess the ability to flex and adapt without fracturing or breaking. This remarkable capability is a result of their unique composition, which includes nodular graphite inclusions that provide excellent ductility. The flexibility of ductile iron pipes allows for the absorption and even distribution of stress along the pipe wall, preventing concentrated points of strain that could lead to failure. This characteristic enables the pipes to accommodate ground movement, settlement, and other external factors that may result in deflection. Moreover, ductile iron pipes possess a high modulus of elasticity, ensuring they can endure significant deformation before reaching their ultimate limit. This property ensures the pipes maintain their structural integrity even when subjected to substantial deflection. Additionally, the joint system utilized in ductile iron pipe installations contributes to their ability to handle pipe deflection. The restrained joint design guarantees a tight and secure connection between pipe sections, reducing the potential for joint separation or leakage caused by deflection-induced stress. All in all, ductile iron pipes exhibit excellent resistance to pipe deflection. Their flexibility, high modulus of elasticity, and dependable joint system make them the preferred choice for a wide range of applications, including water distribution, wastewater management, and sewer systems.
