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: What is the expected burst pressure of ductile iron pipes?
- The expected burst pressure of ductile iron pipes can vary depending on various factors such as the pipe diameter, wall thickness, and the specific grade of ductile iron used. However, in general, ductile iron pipes typically have a burst pressure ranging from 350 to 700 psi (pounds per square inch).
- Q: Can ductile iron pipes be used for underground fire hydrant systems?
- Indeed, underground fire hydrant systems can utilize ductile iron pipes. Renowned for their robustness and endurance, ductile iron pipes are well-suited for subterranean usage. They exhibit remarkable resistance against corrosion and possess the ability to endure significant pressures, both of which are indispensable prerequisites for fire hydrant systems. Moreover, ductile iron pipes boast an extended lifespan, diminishing the necessity for frequent replacements and upkeep, thereby rendering them a financially prudent option for fire hydrant systems.
- Q: What is the expected buoyancy of ductile iron pipes?
- The expected buoyancy of ductile iron pipes can vary depending on several factors such as the diameter, wall thickness, and the specific gravity of the fluid being transported. However, in general, ductile iron pipes are known for their relatively low buoyancy compared to other materials like plastic or concrete. Due to their higher density and weight, ductile iron pipes tend to have a greater resistance to buoyancy forces. This makes them suitable for applications where buoyancy is a concern, such as water and wastewater transmission systems. The combination of their inherent strength and weight helps to keep the pipes grounded and prevents them from floating or rising to the surface. It is important to note that even though ductile iron pipes have lower buoyancy compared to other materials, they may still experience some level of buoyancy in certain scenarios, especially when the fluid being transported has a lower specific gravity. To mitigate this potential issue, additional measures such as anchoring or ballasting may be employed to ensure the stability and integrity of the pipeline system. Overall, 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 appropriate pipe material and design for optimal performance and safety.
- Q: Can ductile iron pipes be used in areas with high soil liquefaction potential?
- Ductile iron pipes can be used in areas with high soil liquefaction potential, but certain precautions and considerations need to be taken into account. Soil liquefaction is a phenomenon in which saturated soil temporarily loses its strength and behaves like a liquid during an earthquake or other seismic events. Ductile iron pipes are known for their strength, durability, and resistance to external loads, making them suitable for various applications, including water and wastewater transportation. However, when it comes to areas with high soil liquefaction potential, additional measures should be considered to ensure the pipes' performance and integrity. One crucial factor to consider is the pipe's installation depth. Ductile iron pipes should be installed at a sufficient depth below the ground surface to minimize the effects of soil liquefaction. The depth will vary depending on soil conditions and the level of seismic activity in the area. Consulting with geotechnical engineers and following local building codes and regulations is essential to determine the appropriate installation depth. Furthermore, proper backfill materials and compaction techniques must be employed during the pipe installation process. Using granular materials, such as crushed stone or gravel, for backfill can help improve the soil's stability and reduce the potential for liquefaction. Adequate compaction of the backfill is also necessary to ensure the pipes' stability and prevent settlement or movement during seismic events. Moreover, it is recommended to use flexible joints, such as restrained joints or push-on joints, when installing ductile iron pipes in areas prone to soil liquefaction. These joints allow for some movement and flexibility, which can help absorb the ground's movement during an earthquake, reducing the stress on the pipes and minimizing the risk of damage. Regular inspection and maintenance of the ductile iron pipes are crucial in high soil liquefaction potential areas. Monitoring for any signs of movement, settling, or damage should be conducted, and any necessary repairs or reinforcements should be promptly addressed to ensure the pipes' continued performance and safety. In conclusion, ductile iron pipes can be used in areas with high soil liquefaction potential, but careful consideration of installation depth, proper backfill materials and compaction, the use of flexible joints, and regular maintenance are crucial to ensuring their optimal performance and longevity. Consulting with geotechnical engineers and following local building codes and regulations is highly recommended to ensure the pipes' suitability in such areas.
