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:Ductile iron pipe is how many years warranty: In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.

Q:How are ductile iron pipes protected from external damage?: Ductile iron pipes are protected from external damage through the application of protective coatings. These coatings act as a barrier, shielding the pipes from corrosion and other forms of external damage. Additionally, the pipes may be encased in concrete or installed in a casing pipe to provide further protection against external forces and impacts.

Q:Are ductile iron pipes resistant to chemical attacks?: Generally, ductile iron pipes exhibit resistance to chemical attacks. The high corrosion resistance of ductile iron makes it suitable for a wide range of applications, including water and wastewater systems. To further enhance their resistance to chemical attacks, ductile iron pipes are commonly lined with a protective coating such as cement mortar or epoxy. This lining acts as a barrier between the pipe material and corrosive substances, preventing any degradation of the iron. However, it is important to consider that the level of resistance may vary depending on the specific chemical being transported, as well as the concentration and temperature of the solution. Therefore, it is advisable to seek the guidance of experts or engineers to ensure the appropriateness of ductile iron pipes for specific chemical environments.

Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?: Then answer your question: first, the strength of ductile iron is much higher than that of ordinary low carbon steel, such as Q235. Corrosion resistance is much higher than that of ordinary steel pipe and the cost is lower than that of ordinary steel pipe. Second, large diameter steel pipe can only be made of spiral welded pipe, seamless steel pipe is particularly expensive, will not be used. The welded pipe is welded, easy to corrosion water leakage. Third, galvanizing is also a life and very expensive, the pipe has a fluid will wear on the inner wall, zinc plating is meaningless. Galvanized pipe is generally used as a water supply pipe, large caliber water pipes, such as more than 250, and now do not use steel pipes, mostly plastic pipes

Q:Are ductile iron pipes suitable for bridge crossings?: Indeed, bridge crossings are well-suited for the utilization of ductile iron pipes. Renowned for their exceptional strength and durability, ductile iron pipes present a dependable option for a wide range of applications, including bridge crossings. These pipes possess the capacity to endure substantial loads and exhibit resistance to corrosion, a particularly vital attribute when considering the challenging environmental conditions that bridge crossings may expose them to. Moreover, ductile iron pipes possess the remarkable ability to flex and withstand ground movement, rendering them an optimal choice for bridge crossings where the ground may experience shifting or settling over time. In conclusion, ductile iron pipes offer the necessary characteristics to guarantee the secure and efficient conveyance of fluids or materials across bridges.

Q:Are ductile iron pipes suitable for use in desalination plants?: Yes, ductile iron pipes are suitable for use in desalination plants. Ductile iron is known for its high strength and durability, making it capable of withstanding the harsh conditions and corrosive nature of desalination processes. Additionally, ductile iron pipes have excellent resistance to internal and external corrosion, making them a reliable choice for transporting the high-pressure brine and freshwater in desalination plants.

Q:What is the typical lifespan of ductile iron pipes?: The lifespan of ductile iron pipes can differ based on multiple factors, including pipe quality, environmental conditions, and maintenance practices. On average, these pipes typically last approximately 75 to 100 years. This longevity establishes them as a sturdy and enduring choice for water and sewage transport systems. Through correct installation and consistent upkeep, these pipes can endure corrosion, pressure, and other external elements, guaranteeing their durability and dependability. Furthermore, advancements in coatings and linings have extended the lifespan of ductile iron pipes, making them an exceptional option for infrastructure projects.

Q:Can ductile iron pipes be used for rainwater harvesting systems?: Yes, ductile iron pipes can be used for rainwater harvesting systems. Ductile iron pipes are known for their durability and strength, making them suitable for various applications, including rainwater collection and storage. They can effectively transport rainwater from collection points to storage tanks, ensuring a reliable and efficient rainwater harvesting system.

Q:Can ductile iron pipe be used for pump stations?: Certainly, pump stations can utilize ductile iron pipe. Ductile iron pipe is extensively employed in underground water and wastewater systems, including pump stations. It provides numerous benefits, including remarkable strength, durability, and resistance to corrosion, thus ensuring its appropriateness for such purposes. Moreover, ductile iron pipe seamlessly harmonizes with various pump types and is renowned for its extended lifespan, rendering it an optimal selection for pump station projects.

Q:How do ductile iron pipes perform in cold weather conditions?: Ductile iron pipes are known for their excellent performance in cold weather conditions. Unlike other materials, such as cast iron or PVC, ductile iron has exceptional resistance to low temperatures. This is primarily due to its unique microstructure, which enables it to withstand extreme weather conditions without compromising its structural integrity. In cold weather, ductile iron pipes have a low coefficient of thermal expansion, meaning they do not contract or expand significantly with temperature changes. This characteristic allows them to remain stable and resistant to cracking or bursting, even in freezing temperatures. Additionally, the ductile iron material has high impact resistance, which further enhances its ability to withstand the stress imposed by cold weather conditions. Furthermore, ductile iron pipes have a protective lining, typically made of cement mortar or epoxy, which acts as an additional barrier against the effects of cold weather. This lining prevents the formation of ice on the inner surface of the pipes, reducing the risk of blockages or reduced flow capacity. Overall, ductile iron pipes are a reliable choice for cold weather conditions. Their durability, low thermal expansion, and protective lining make them highly resistant to the challenges posed by freezing temperatures. Whether it is for water supply, sewer systems, or other applications, ductile iron pipes have proven their ability to perform effectively even in the harshest winter climates.
