Q: What's the difference between grey cast iron pipe and ductile iron pipe?: Ductile iron pipe is a kind of casting alloy developed in the late 1940s. It is a kind of spheroidal graphite cast iron which is added into the molten iron by adding inoculant and inoculant. The mechanical properties of spherical graphite, so much more better than that of grey cast iron, cast iron, close to the steel, but the price is lower than steel, and still has many excellent properties of ordinary cast iron, such as good casting, shock absorption, machinability and low notch sensitivity etc.. Therefore, many important mechanical parts, such as crankshaft, connecting rod, gear, valve body and cylinder liner, can be made of ductile iron to save steel and reduce cost.

Q: Will the cast iron pipes rust?: Qualified ductile iron pipes can be used for more than a hundred years. The main place where rust is easily exposed is where the outer wall meets the soil because of its high humidity and high oxygen content. Qualified anticorrosion can effectively resist rust, its process principle can not give you the details. Although the wall has a long flow of water, but oxygen scarce, compared with the outer wall is not easy to corrosion, but there is cement lining is necessary.

Q: How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?: Ductile cast iron used for more than 18 by adding nodulizer, 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.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.

Q: Can ductile iron pipe be used for irrigation pumping stations?: Yes, ductile iron pipe can be used for irrigation pumping stations. Ductile iron pipe is commonly used in various applications, including irrigation systems, due to its durability and strength. It has high tensile strength and can withstand high pressure and heavy loads, making it suitable for irrigation pumping stations. Additionally, ductile iron pipe is resistant to corrosion, which is beneficial in irrigation systems where water is present. It is also easy to install and maintain, making it a cost-effective choice for irrigation projects.

Q: Can ductile iron pipes be used in oil or gas transmission pipelines?: Yes, ductile iron pipes can be used in oil or gas transmission pipelines. Ductile iron is a type of cast iron that has enhanced properties, such as higher tensile strength and ductility, making it suitable for a wide range of applications, including pipeline systems for oil and gas transmission. Ductile iron pipes have excellent corrosion resistance, which is crucial for pipelines that transport oil or gas over long distances. This material is highly resistant to external factors like soil chemicals, moisture, and corrosive gases commonly found in the oil and gas industry. Additionally, ductile iron pipes can withstand high pressures and temperatures, making them suitable for the demands of oil and gas transmission. Furthermore, ductile iron pipes have good impact resistance, allowing them to absorb and withstand external forces like ground movement or heavy loads. This durability ensures the integrity and longevity of the pipeline system, minimizing the risk of leaks or failures. Overall, ductile iron pipes offer a reliable and cost-effective solution for oil and gas transmission pipelines. Their robustness, corrosion resistance, and ability to withstand high pressures and temperatures make them a viable choice for this critical infrastructure.

Q: Can ductile iron pipes be used in earthquake-prone areas?: Ductile iron pipes are suitable for use in areas prone to earthquakes. This material, known for its strength and flexibility, can withstand the movement and vibrations caused by seismic activity. Its exceptional ductility means it can deform under stress without fracturing or breaking. Consequently, ductile iron pipes are capable of absorbing the energy produced during an earthquake, minimizing the risk of pipe failure or rupture. Moreover, these pipes have a proven track record in seismic zones, attesting to their resilience and dependability in such regions. Nevertheless, it is crucial to emphasize the importance of proper installation and design considerations, including the use of appropriate jointing methods and ensuring adequate anchoring. These factors are crucial to guarantee the optimal performance of ductile iron pipes in earthquake-prone areas.

Q: Can ductile iron pipes be used for cooling water systems?: Yes, ductile iron pipes can be used for cooling water systems. Ductile iron pipes are known for their durability, strength, and corrosion resistance, making them suitable for a wide range of applications, including cooling water systems. These pipes have the capacity to handle high pressure and temperature fluctuations, making them ideal for circulating and transporting cooling water. Additionally, ductile iron pipes have a smooth internal surface that reduces friction and minimizes the risk of scaling or clogging, ensuring efficient flow of the cooling water. Therefore, ductile iron pipes can be a reliable and efficient choice for cooling water systems.

Q: Disadvantages of ductile iron pipes: The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.

Q: How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?: This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.

Q: How are ductile iron pipes protected against stray current corrosion?: Ductile iron pipes are protected against stray current corrosion through the implementation of various measures. One common method is the installation of a protective coating, such as an epoxy or zinc coating, on the external surface of the pipes. This coating acts as a barrier, preventing direct contact between the pipe and the surrounding soil or water. Additionally, cathodic protection systems, such as impressed current or sacrificial anode systems, can be employed to further protect the pipes. These systems help to control and redirect stray currents, minimizing their impact on the ductile iron pipes and preventing corrosion.
