Ductile Iron Cast Pipe is without any defects compare with tradition casting tech, which has many advantages particularly as follow:
(1) High density. In the "vertical upward casting" process, the melt iron of centre liquid column in center crystallizer is continuously feeding for volume shrinkage caused by condensation tube at outer circumference , which lead to be free of shrinkage porosity.
(2) High purity. When melt iron pouring, the mixed impurities such as gas, dross, sand grain which are lighter than melt iron could be eliminated at furnace mouth, its impossible to enter into the crystallizer through the channel, so the melt iron into the crystallizer is very pure.
(3) Strength with toughness. The cooling speed provided by continuous crystallizer is 30 times than sand casting and 5 times than centrifugal casting, and doesn't produce white iron, the eutectic cell volume of continuous cast iron is one eighth to one tenth compare with traditional cast iron. The density of graphite nodule in ductile iron can reach 300-700 pcs/mm2. Therefore, all reason above improve the strength and toughness of continuous cast iron.
(4) Free machining. The high speed cooling make the hardening phase (such as boride, steadite) not appear like reticular, massive or thick, but diffuse like fish bone and pane in shape, moreover, there are tiny graphite flakes inlaid hardening phase. It's free machining in BrinellHardness the range of 250-300HB. However, the Brinell Hardness of 250 is top limit to common metal materials.
(5) Uniform composition of tube wall. The convection mixing of liquid column caused by marching type drawing in crystallizer make the composition of tube wall well-distributed, and concentration gradient very little.
(6) High productivity. To the wall thickness of tube under 10mm, the speed of continuous casting is 1 meter/min, to the wall thickness of tube under 20mm, the speed of continuous casting is 0.5 meter/min, which is high efficiency that centrifugal or other casting tech couldn't reach.

- Q: How are ductile iron pipes protected against root intrusion?
- Ductile iron pipes are protected against root intrusion through various methods and techniques. One commonly used approach is the application of root inhibitors or growth regulators. These chemicals are typically injected into the soil around the pipes, creating a barrier that inhibits root growth near the pipe. This helps prevent roots from penetrating the pipe and causing damage. Another method involves the use of physical barriers such as root barriers or sleeves. These are installed around the pipes to physically block the roots from accessing them. Root barriers are typically made of materials like plastic or metal and are designed to withstand the pressure exerted by growing roots. Additionally, regular maintenance practices such as periodic inspections and cleaning are essential in preventing root intrusion. By monitoring the condition of the pipes and removing any existing root masses, the risk of further root intrusion can be minimized. It is worth noting that preventative measures are more effective than reactive measures when it comes to protecting ductile iron pipes against root intrusion. Therefore, implementing proactive strategies during the installation phase, such as proper pipe bedding and alignment, can help reduce the likelihood of root intrusion in the first place. Overall, a combination of chemical treatments, physical barriers, and appropriate maintenance practices can significantly enhance the protection of ductile iron pipes against root intrusion, ensuring their long-term durability and functionality.
- Q: Disadvantages of ductile iron pipes
- Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron.
- Q: Can ductile iron pipes be used in areas with high soil erosion?
- Due to their inherent strength and durability, ductile iron pipes can be utilized in regions with substantial soil erosion. Ductile iron, a type of iron treated with graphite nodules, enhances its flexibility and tensile strength, rendering it highly resistant to cracking and breaking, even in extreme conditions. In areas with high soil erosion, the ground tends to shift and move, imposing significant stress on underground pipes. Nevertheless, ductile iron pipes exhibit high resistance to external loading and can endure the pressures exerted by the surrounding soil. Their reliability in such environments has been extensively tested and proven. Moreover, ductile iron pipes boast a lengthy lifespan, often exceeding 100 years, making them a cost-effective choice for areas with substantial soil erosion. Their corrosion resistance and structural integrity render them suitable for installation in diverse soil conditions, including those susceptible to erosion. It is crucial to note that proper installation techniques, like employing appropriate bedding and backfill materials, must be adhered to in order to ensure the optimal performance of ductile iron pipes in areas with high soil erosion. Additionally, regular inspection and maintenance should be carried out to promptly identify any potential issues and prevent damage resulting from soil erosion. All in all, ductile iron pipes serve as a dependable and durable option for regions with high soil erosion, providing enduring and efficient water distribution and wastewater management systems.
- Q: Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
- Ductile iron is good, its tensile properties are destined to withstand low temperatures, gray cast iron is a little bit worse.
- Q: Are there any limitations to the length of ductile iron pipe sections?
- Limitations exist regarding the length of ductile iron pipe sections. Typically, these limitations stem from practical concerns such as transportation, installation, and handling. Longer pipe sections can present difficulties when it comes to transportation and maneuverability, particularly in areas with limited access or challenging terrain. Moreover, longer pipe sections may be more susceptible to damage during installation since proper alignment and joining can be more challenging. Manufacturing capabilities also impose limitations. Ductile iron pipes are typically produced in standard lengths, which can vary depending on the manufacturer and the specific application. These standard lengths are designed to strike a balance between transportation, installation, and overall pipe performance. In addition, longer pipe sections may pose challenges related to temperature variations and subsequent expansion and contraction. Ductile iron pipes are prone to thermal expansion and contraction, and longer sections may experience greater stress and strain as a result. Therefore, while there is no definitive maximum length for ductile iron pipe sections, practical considerations and manufacturing capabilities dictate the use of standard lengths that consider various factors such as transportation, installation, and performance.
