4.FAQ:
We have organized several common questions for our clients，may help you sincerely
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.
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: Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
- The situation in use abroad seems. It is considered that the corrosion of the inner wall of the centrifugal centrifugal ductile iron pipe and the rupture of the pipe are easy to occur when the content of chloride ion exceeds 5O0PPm in the pipe laying environment. This is mainly because, because the cement paste protection layer is the late spraying construction, it is not good to combine with the prefabricated core tube. It often causes water or moisture to seep in and causes oxidation and corrosion of the prestressing steel bars, resulting in fracture. The adhesive interface between cement mortar and centrifugally cast iron pipe is not reasonable. Because of the water absorption of cement, when the water enters the pipe, it is easy to destroy the interface and corroded the inner wall of the centrifugally cast iron pipe. Because it is a brittle material, it is easy to cause sudden accidents.
- Q: How do ductile iron pipes handle ground movement or settlement?
- Ductile iron pipes are renowned for their remarkable strength and flexibility, enabling them to effectively manage ground movement or settlement. Ground movement or settlement pertains to the natural shifts or settling of the earth's surface, which can exert stress on subterranean infrastructure such as pipes. Concerning ground movement, ductile iron pipes possess the advantage of enduring and absorbing the pressure and movement caused by shifting soil. The material's ductility permits the pipes to flex and bend to a certain extent without fracturing. This flexibility aids in distributing the load and minimizing the potential for harm. Additionally, ductile iron pipes exhibit high resistance to cracking or fracturing, even under extreme circumstances. This resilience stems from the material's unique microstructure, which imparts excellent tensile strength and impact resistance. Consequently, ductile iron pipes can withstand external forces and ground settlement without compromising their integrity. To further augment their capacity to handle ground movement or settlement, ductile iron pipes are frequently installed using flexible joints. These joints allow for slight movement and accommodate any shifting or settling of the ground. Furthermore, proper bedding and backfilling techniques are employed during installation to provide added support and stability. Overall, ductile iron pipes possess a proven track record in managing ground movement or settlement. Their strength, flexibility, and resistance to cracking establish them as a dependable choice for subterranean infrastructure, ensuring the durability and efficiency of water distribution systems.
- Q: What is the maximum temperature that ductile iron pipe can handle?
- The ability of ductile iron pipe to withstand high temperatures varies depending on factors such as the grade of ductile iron, the length of time exposed to heat, and the presence of external factors like corrosive environments. In general, ductile iron pipes can tolerate temperatures up to 400-450 degrees Fahrenheit (204-232 degrees Celsius) for short periods. However, it is crucial to refer to the manufacturer's specifications and guidelines to determine the exact maximum temperature limits for a specific grade of ductile iron pipe. Additionally, it is advisable to consider the consequences of thermal expansion, potential loss of mechanical properties, and any additional protective measures that may be necessary when operating at elevated temperatures.
- Q: Is ductile iron pipe breakable?
- The ductile iron pipe has many uses in our city construction, for our city water supply, gas supply and so on. But ductile iron pipes are also very useful in sewage disposal.

It is resistant to corrosion, chemicals, and UV rays, making it suitable for both aboveground and underground installations. HDPE pipe is also known for its leak-free joints and long lifespan. 3. PEX (Cross-linked Polyethylene) Pipe: PEX pipe, a flexible plastic pipe, is commonly utilized for water distribution in residential and commercial settings. It is recognized for its ability to withstand freezing, scaling, and corrosion. PEX pipe is easy to install, has fewer joints, and is highly durable. 4. Copper Pipe: Copper pipe has a long history of use in water distribution due to its exceptional resistance to corrosion and extended lifespan. Although it is more expensive than other alternatives, copper pipe is renowned for its reliability and ability to handle high pressure. 5. Steel Pipe: Steel pipe is a robust and durable option for water distribution, particularly in high-pressure scenarios. It can endure extreme temperatures and resist external loads. However, steel pipe is more costly and requires specialized installation techniques. When selecting an alternative to ductile iron pipe for water distribution, it is crucial to consider factors such as cost, durability, corrosion resistance, installation requirements, and specific project needs.
- Q: What is the weight of ductile iron pipes?
- The weight of ductile iron pipes can vary depending on their size and wall thickness. On average, a 10-foot length of 6-inch diameter ductile iron pipe can weigh approximately 180 pounds. However, it is important to note that different manufacturers may have slight variations in weight due to differences in manufacturing processes and materials used. It is recommended to consult specific product specifications or contact the manufacturer for accurate weight information.
