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: Ductile iron pipe in the direction of it?
- The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
- Q: Principles for the antiseptic treatment of ductile iron pipes
- The principle that the antiseptic treatment of ductile iron pipes must be complied with is that.1. internal and external surface coating shall be kept clean, remove rust and impurities2. after coating on the inside and outside surface, the coating should be even and smooth, firm and firm, and shall not be abnormal because of climate change3. coating for water delivery should be insoluble in water, no peculiar smell, harmful impurities content
- Q: What are the different types of restrained joints for ductile iron pipe?
- Some of the different types of restrained joints for ductile iron pipe include mechanical joints, push-on joints, and restrained push-on joints. Mechanical joints use bolts and gaskets to create a tight seal, while push-on joints rely on a rubber gasket to provide a secure connection. Restrained push-on joints incorporate additional features such as external restraints or wedges to prevent pipe movement.
- Q: Method for cutting cast iron pipe
- Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
- Q: Can ductile iron pipes be used for geothermal energy systems?
- Yes, ductile iron pipes can be used for geothermal energy systems. Ductile iron pipes are known for their strength, durability, and resistance to corrosion, making them suitable for various applications, including geothermal energy systems. They can effectively handle the high pressures and temperatures associated with geothermal energy production, making them a reliable choice for transporting hot water or steam. Additionally, ductile iron pipes have a long lifespan, reducing maintenance and replacement costs for geothermal energy systems.
- Q: What is the expected internal lining material for ductile iron pipes?
- Typically, the anticipated internal lining materials for ductile iron pipes are either cement mortar lining or polyethylene lining. Cement mortar lining serves as a protective layer on the inner surface of the ductile iron pipe, shielding it from corrosion and prolonging its lifespan. Conversely, polyethylene lining is a thermoplastic substance that possesses resistance against corrosion, abrasion, and chemicals, making it well-suited for situations involving aggressive substances or poor water quality. Depending on the project's specific requirements and conditions, both lining materials offer their own advantages and are commonly utilized within the industry.
- Q: Can ductile iron pipes be used for large-scale irrigation systems?
- Yes, ductile iron pipes can be used for large-scale irrigation systems. Ductile iron pipes are known for their strength, durability, and corrosion resistance, making them suitable for various applications, including irrigation. They can handle high-pressure water flow and provide long-lasting performance, making them a reliable choice for large-scale irrigation systems.
- Q: Can ductile iron pipes be used in areas with high water velocity?
- Yes, ductile iron pipes can generally be used in areas with high water velocity. Ductile iron is known for its strength and durability, making it suitable for various applications, including high-velocity water flow. However, it is important to consider factors like pipe size, wall thickness, and proper installation techniques to ensure the pipes can handle the specific velocity conditions effectively.
- Q: Can ductile iron pipes be used for underground fire protection systems?
- Ductile iron pipes are indeed applicable for underground fire protection systems. Their exceptional strength and durability render them suitable for enduring the intense pressure and high temperatures that may arise during a fire. Moreover, these pipes exhibit significant resistance to corrosion, a vital attribute for long-term underground usage. In addition, they possess exceptional flow characteristics, enabling swift and efficient water delivery for extinguishing fires. All in all, ductile iron pipes prove to be a dependable and efficient selection for underground fire protection systems.
- Q: How are ductile iron pipes connected together?
- Ductile iron pipes are typically connected together using a variety of methods, depending on the specific application and requirements. The most common method of connecting ductile iron pipes is through mechanical joint fittings. These fittings consist of a bell end on one pipe and a spigot end on the other, which are joined together using a rubber gasket and bolts or clamps. The rubber gasket provides a watertight seal, while the bolts or clamps secure the joint and prevent any movement or separation. Another method of connecting ductile iron pipes is through flanged joints. Flanged joints involve attaching a flange to the end of each pipe, which are then bolted together using bolts and nuts. This method is commonly used in larger diameter pipes or in situations where the pipes need to be easily disassembled. In addition to mechanical joint fittings and flanged joints, ductile iron pipes can also be connected using push-on or restrained joint fittings. Push-on joints utilize a rubber gasket that is pushed onto the spigot end of the pipe, creating a secure and watertight connection. Restrained joints, on the other hand, incorporate additional features such as welded-on collars or mechanical devices to prevent movement and provide added strength to the joint. Overall, the method of connecting ductile iron pipes together depends on factors such as pipe diameter, pressure requirements, and the specific application. It is important to follow the manufacturer's guidelines and industry standards to ensure proper installation and reliable performance of the connected pipes.
