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: Can ductile iron pipes be used for underground steam distribution systems?
- Yes, ductile iron pipes can be used for underground steam distribution systems. Ductile iron has excellent strength, durability, and resistance to high temperatures, making it suitable for carrying steam underground. Additionally, its corrosion resistance properties ensure a longer lifespan and reduced maintenance costs.
- Q: Are ductile iron pipes suitable for use in geothermal applications?
- Yes, ductile iron pipes are suitable for use in geothermal applications. They possess excellent strength and corrosion resistance, making them resistant to the high temperatures and corrosive nature of geothermal fluids. Additionally, their ductility allows them to withstand the expansion and contraction associated with geothermal systems, making them a reliable choice for such applications.
- Q: What are the common methods for leak detection in ductile iron pipes?
- Some common methods for leak detection in ductile iron pipes include visual inspection, acoustic leak detection, pressure testing, and tracer gas leak detection. Visual inspection involves physically inspecting the pipes for any visible signs of leaks, such as water stains or wet spots. Acoustic leak detection uses specialized equipment to listen for sounds of leaking water within the pipes. Pressure testing involves pressurizing the pipes to a certain level and checking for any drop in pressure, which could indicate a leak. Tracer gas leak detection involves injecting a gas, such as helium or hydrogen, into the pipes and using a gas detector to locate any escaping gas, which would indicate a leak.
- Q: Can ductile iron pipe be used for compressed air systems?
- Indeed, compressed air systems can make use of ductile iron pipe. Ductile iron pipe, renowned for its robustness, endurance, and crack resistance, proves suitable for numerous applications, including compressed air systems. It possesses the capability to endure high pressures and exhibits a lesser tendency to corrode or rust in comparison to alternative materials. Nonetheless, it becomes crucial to guarantee that the ductile iron pipe is adequately sized and installed to accommodate the precise demands of the compressed air system. Furthermore, conducting regular maintenance and inspections becomes imperative to avert any potential problems or damages.
- Q: How do ductile iron pipes perform in high-altitude areas?
- Ductile iron pipes perform well in high-altitude areas as they are highly resistant to corrosion and can withstand extreme temperature variations. The material's flexibility and strength make it suitable for handling increased pressure caused by altitude changes, ensuring reliable water distribution systems even in mountainous regions.
- Q: What is the disadvantage of nodular cast iron in excess of silicon?
- Therefore, the increase of silicon content in nodular iron greatly improves the strength index and reduces toughness. Ductile iron has a greater crystalline undercooling and a tendency to chill when treated by spheroidizing, and silicon reduces this tendency.
- Q: What does "K8" mean in ductile iron pipe grades?
- K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
- Q: Are ductile iron pipes suitable for wastewater pumping stations?
- Yes, ductile iron pipes are suitable for wastewater pumping stations. Ductile iron has high tensile strength, durability, and corrosion resistance, making it ideal for handling the abrasive and corrosive nature of wastewater. Additionally, ductile iron pipes have excellent pressure-bearing capabilities, ensuring reliable and efficient operation in wastewater pumping stations.
- Q: How are ductile iron pipes protected during transportation and storage?
- Various methods are employed to protect ductile iron pipes during transportation and storage, ensuring their integrity and preventing potential damage. The first step involves applying a protective layer, such as epoxy or zinc, to act as a barrier against corrosion. This coating effectively safeguards the pipes from moisture and other corrosive elements during transit and storage. To further safeguard the pipes, they are often bundled together and secured with straps or bands, preventing any movement or shifting that could cause mechanical damage. This bundling not only ensures the pipes remain intact but also facilitates easier handling and transportation in an organized manner. During transportation, the pipes are typically loaded onto pallets or placed in crates, providing additional protection and stability. This minimizes the risk of accidental impact or rough handling that may result in cracks or fractures. Proper labeling and marking of the pipes is crucial to ensure appropriate handling. This includes displaying handling instructions, weight limits, and pipe specifications, preventing mishandling and damage during transportation. Equally important are the storage conditions for maintaining the integrity of ductile iron pipes. They should be stored in a clean, dry, and well-ventilated area, protecting them from moisture and humidity. Direct sunlight and extreme temperatures should be avoided to prevent any potential degradation of the protective coating. In conclusion, protecting ductile iron pipes during transportation and storage involves the application of protective coatings, bundling and securing, suitable packaging materials, proper handling and labeling, and storage in appropriate conditions. These measures guarantee the pipes' quality and structural integrity, ensuring they arrive at their destination in optimal condition.
- Q: Ductile iron pipe, socket connection, pipe length, you can cut open it?
- Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
