4.FAQ:
We have organized several common questions for our clients，may help you sincerely：
Q: Why would you choose ductile iron pipe rather than other pipe materials?
A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.
Q:Why can you guarantee the inner of pipes can’t be corroded?
A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.
- Q: Are ductile iron pipes suitable for industrial water systems?
- Yes, ductile iron pipes are suitable for industrial water systems. Ductile iron pipes are known for their strength, durability, and corrosion resistance, making them an ideal choice for transporting water in industrial settings. They can withstand high-pressure and heavy-duty applications, making them suitable for conveying water in large-scale industrial facilities such as power plants, factories, and chemical plants. Additionally, ductile iron pipes have the ability to handle a wide range of temperatures, making them suitable for both hot and cold water systems. Their inherent flexibility allows for easy installation and maintenance, further adding to their suitability for industrial water systems. Overall, ductile iron pipes are a reliable and cost-effective solution for industrial water transportation needs.
- Q: How do ductile iron pipes handle pressure surges in pumping stations?
- Ductile iron pipes are specifically designed to handle pressure surges in pumping stations effectively. The inherent strength and flexibility of ductile iron make it well-suited to withstand the sudden increase in pressure that can occur during pump start-up or shutdown. One of the key features of ductile iron pipes is their ability to absorb and dissipate energy. When a pressure surge occurs, the ductile iron pipes have the capacity to absorb the excess pressure and distribute it evenly throughout the pipe network. This helps to minimize the impact of the surge and prevent any potential damage to the pipes or the pumping station. Additionally, ductile iron pipes have a high resistance to impact and stress, which further enhances their ability to handle pressure surges. The pipes are manufactured using a unique process that imparts strength and durability, allowing them to withstand the forces exerted during pressure fluctuations without any significant deformation or failure. Furthermore, ductile iron pipes have a smooth internal surface, which reduces friction and turbulence within the pipe network. This smooth flow characteristic helps to mitigate the effects of pressure surges by allowing the water to move efficiently without creating additional stress on the pipes. In summary, ductile iron pipes are specifically engineered to handle pressure surges in pumping stations by absorbing and dissipating the excess pressure, withstanding the impact and stress, and promoting smooth flow. Their robustness and reliability make them an ideal choice for applications where pressure fluctuations are common, ensuring the longevity and efficiency of the pumping infrastructure.
- Q: Are ductile iron pipes resistant to acid attacks?
- Yes, ductile iron pipes are generally resistant to acid attacks. Ductile iron has a protective layer of graphite and a dense matrix structure that helps in preventing the penetration of acid. However, prolonged exposure to highly corrosive acids or extreme pH levels may still cause some degradation over time.
- Q: What is the minimum pipe diameter of cast iron pipe?
- Cast iron pipe: cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small.
- Q: Can ductile iron pipes be used for railway bridges?
- Yes, ductile iron pipes can be used for railway bridges. They are commonly used in bridge construction due to their high strength, durability, and resistance to corrosion. Additionally, ductile iron pipes can withstand heavy loads and provide excellent structural support, making them suitable for railway bridge applications.
- Q: Are ductile iron pipes suitable for fire protection systems?
- Yes, ductile iron pipes are suitable for fire protection systems. Ductile iron is known for its strength, durability, and ability to withstand high pressure and heat, making it an ideal choice for fire protection systems. Additionally, ductile iron pipes have excellent corrosion resistance, which is crucial for ensuring the longevity and reliability of fire protection systems.
- Q: What is the average weight of ductile iron pipes?
- The average weight of ductile iron pipes can vary depending on the specific dimensions and specifications of the pipe. However, as a general guideline, ductile iron pipes typically range in weight from around 50 pounds per foot to 200 pounds per foot. The weight of a ductile iron pipe is influenced by factors such as the pipe's diameter, wall thickness, and length. It is important to note that these are average weights, and the actual weight of a specific ductile iron pipe may vary. To determine the exact weight of a ductile iron pipe, it is advisable to refer to the manufacturer's specifications or consult engineering guidelines.
- Q: How are ductile iron pipes made?
- The manufacturing of ductile iron pipes involves a specific process called centrifugal casting. In this process, molten iron is poured into a rotating mold, typically made of steel. The rotation of the mold creates centrifugal force, which evenly distributes the molten iron, resulting in high-quality pipes. To start the manufacturing process, a mixture of scrap iron, steel, and recycled material is melted at extremely high temperatures in a furnace. Once the molten iron reaches the desired temperature and consistency, it is ready to be cast into pipes. To prevent the molten iron from cooling too quickly, the rotating mold is preheated. This preheating also contributes to achieving a smooth surface finish on the pipes. The molten iron is then poured into the rotating mold through a central sprue. As the mold spins, centrifugal force forces the molten iron against the inner walls of the mold. This rapid solidification results in dense, strong, and corrosion-resistant pipes. The centrifugal force also helps remove impurities or slag from the inner surface of the pipe, further enhancing its quality. Once the casting process is complete, the mold is allowed to cool, and the pipe is removed. The pipes undergo various tests to ensure they meet the required quality standards. These tests include checking dimensions, mechanical properties, and surface finish. After passing the quality tests, ductile iron pipes are typically coated with a protective lining to prevent corrosion and extend their lifespan. The type of lining used, such as cement mortar, epoxy, or polyethylene, depends on the intended application of the pipes. In conclusion, the centrifugal casting process is utilized to manufacture ductile iron pipes. This process ensures the production of high-quality pipes that are strong, corrosion-resistant, and have a smooth surface finish.
- Q: What is the cost of ductile iron pipe compared to other pipe materials?
- The cost of ductile iron pipe is generally higher compared to other pipe materials such as PVC or steel due to its superior durability and strength.
- Q: Do ductile iron pipes require pressure testing before installation?
- Yes, ductile iron pipes typically require pressure testing before installation to ensure their integrity and ability to withstand the required pressure and flow conditions.
