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 pipe be used for pressure sewer systems?
- Yes, ductile iron pipe can be used for pressure sewer systems. Ductile iron pipe is known for its strength, durability, and resistance to corrosion, making it a suitable choice for various applications, including pressure sewer systems. It can withstand high pressure and provide a reliable conduit for transporting wastewater under pressure. Additionally, ductile iron pipe has excellent joint integrity, which ensures leak-free connections and minimizes the risk of sewer system failures. Therefore, ductile iron pipe is commonly used in pressure sewer systems due to its structural integrity and long lifespan.
- Q: What are the different pressure classes available for ductile iron pipe?
- The different pressure classes available for ductile iron pipe include Class 100, Class 150, Class 200, Class 250, Class 300, Class 350, and Class 400.
- Q: What's the difference between grey cast iron pipe and ductile iron pipe?
- Ductile iron is close to medium carbon steel and is much cheaper. Vermicular graphite iron is the best, but grey iron is worse and white iron is the worst. Therefore, the quality of ductile iron pipe with better quality and price is superior to other cast iron pipe fittings.
- Q: How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
- The hot dip galvanized welded steel pipe galvanized pipe, galvanized pipe by welding without taking anti rusting measures (furnace welding and welding) steel pipe, seamless steel pipe or other metal pipe of the clarinet, process of hot dip galvanizing, the outer coating and galvanized layer to long-term corrosion of the steel pipe after processing.
- Q: Are ductile iron pipes suitable for use in desalination plants?
- Ductile iron pipes are indeed suitable for use in desalination plants. Desalination plants are facilities that remove salt and other impurities from seawater, turning it into fresh water for consumption or industrial use. These plants require a reliable and durable piping system to transport the treated water to various destinations. Ductile iron pipes are known for their strength, flexibility, and corrosion resistance, making them an ideal choice for desalination plants. These pipes are made from a form of cast iron that has been treated with magnesium to enhance its properties. This treatment gives ductile iron pipes a high tensile strength, allowing them to withstand the high pressures associated with the desalination process. Additionally, desalination plants often use chemicals and other treatment methods to remove impurities from the water. Ductile iron pipes have excellent resistance to corrosion from these chemicals and can withstand the harsh conditions found in desalination plants without deteriorating over time. This ensures the longevity and reliability of the piping system, minimizing the risk of leaks or failures. Furthermore, ductile iron pipes have a smooth internal surface, which helps to minimize friction and pressure loss as water flows through the pipes. This feature is especially important in desalination plants, where efficiency is crucial for the overall operation of the facility. The smoothness of ductile iron pipes allows for efficient water flow, reducing energy consumption and optimizing the desalination process. In conclusion, ductile iron pipes are suitable for use in desalination plants due to their strength, flexibility, corrosion resistance, and smooth internal surface. These pipes provide a reliable and durable piping system that can withstand the high pressures, harsh chemicals, and demanding conditions found in desalination plants.
- Q: What are the typical surge anticipation measures for ductile iron pipe?
- Some typical surge anticipation measures for ductile iron pipe include using surge tanks or pressure relief valves, installing air release valves and surge suppressors, using flexible joint connections, and designing the pipeline with appropriate wall thickness and reinforcement.
- Q: What is the maximum temperature that ductile iron pipe can handle?
- The maximum temperature that ductile iron pipe can handle typically ranges between 350-400 degrees Fahrenheit.
- Q: Are there any specific standards or specifications for ductile iron pipes?
- Yes, there are specific standards and specifications for ductile iron pipes. The most widely recognized standards for ductile iron pipes include ISO 2531, EN 545, and ASTM A536. These standards outline the requirements for the material composition, physical properties, dimensions, and testing methods of ductile iron pipes. Additionally, different countries or regions may have their own specific standards or specifications for ductile iron pipes.
- Q: Are there any special coatings or linings available for ductile iron pipe?
- Yes, there are special coatings and linings available for ductile iron pipe. These coatings and linings are applied to the internal and/or external surfaces of the pipe to provide protection against corrosion and extend the lifespan of the pipe. Some common coatings and linings used for ductile iron pipe include cement mortar lining, polyethylene encasement, epoxy coating, and polyurethane lining. These coatings and linings are designed to prevent the pipe from corroding when in contact with various substances such as water, chemicals, and soil. The specific coating or lining used depends on the application and the environment in which the pipe will be installed.
- Q: How is ductile iron pipe protected against external corrosion?
- Ductile iron pipe is protected against external corrosion through a process called external coating. This involves applying a layer of protective coating, such as asphaltic or epoxy, on the outside surface of the pipe. The coating acts as a barrier, preventing moisture and corrosive substances from coming into contact with the iron, thus reducing the risk of corrosion. Additionally, cathodic protection methods, such as applying sacrificial anodes or using impressed current systems, may be employed to further enhance the corrosion resistance of the ductile iron pipe.
