5.FAQ:
We have organized several common questions for our clients，may help you sincerely：
1.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.
2.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: What are the different methods for joining ductile iron pipe?
- There are several methods for joining ductile iron pipe, each with its own advantages and limitations. One common method is mechanical joint (MJ) coupling, which involves using a rubber gasket and a set of bolts and nuts to create a watertight seal between pipe sections. This method is relatively quick and easy to install, but it requires a skilled technician to ensure proper alignment and bolt tightening to prevent leakage. Another method is flanged joint, where the pipe ends are equipped with flanges that are bolted together using gaskets to create a tight seal. This method allows for easy disassembly and reassembly of pipe sections, making it suitable for applications that require frequent maintenance or modifications. However, it is more expensive and time-consuming compared to other methods. One widely used method is push-on joint (POJ), which involves using a rubber gasket and a special lubricant to slide the pipe ends together. This method provides a reliable and watertight seal, and it is relatively quick and easy to install. However, it requires proper alignment and care to avoid damaging the gasket during assembly. Another option is restrained joint (RJ), which uses a mechanical joint coupling with additional features to resist axial forces or thrusts. This method is commonly used in applications where the pipe is subject to internal pressure, external loads, or seismic activity. It provides a secure and rigid connection but may require specialized tools and training for installation. Finally, welding is another method for joining ductile iron pipe. It involves heating the pipe ends and melting a filler metal to create a permanent bond. This method provides a strong and durable connection, but it requires skilled welders and additional time for preparation, welding, and cooling. Welding is often used for specific applications, such as joining sections of pipe with different diameters or connecting to other materials. In summary, the different methods for joining ductile iron pipe include mechanical joint coupling, flanged joint, push-on joint, restrained joint, and welding. The choice of method depends on factors such as the application requirements, installation time, maintenance needs, and budget.
- Q: What is the expected pressure rating of ductile iron pipes?
- The pressure rating of ductile iron pipes can vary depending on factors like pipe diameter, wall thickness, and installation joint type. However, ductile iron pipes are generally recognized for their durability and ability to handle high pressure. In most instances, ductile iron pipes are designed and produced to meet or surpass industry standards like AWWA C151 or C115/A21.15. These standards establish the minimum pressure rating for ductile iron pipes, which typically range from 150 to 350 psi for water transmission purposes. It's important to note that the pressure rating is also influenced by the pipe's class, which corresponds to the wall thickness. Ductile iron pipes are commonly available in different classes such as Class 50, Class 51, Class 52, etc. Each class has its own pressure rating, with higher classes offering greater strength and pressure resistance. To determine the exact pressure rating, it is advisable to refer to the manufacturer's specifications and guidelines for the specific ductile iron pipes being used. Additionally, other factors like pipe support, installation methods, and operating conditions should be considered to ensure the safe and efficient functioning of the ductile iron pipe system.
- Q: Do ductile iron pipes require internal linings or coatings?
- Ductile iron pipes do not typically require internal linings or coatings. Ductile iron is known for its inherent corrosion resistance, which is primarily due to its composition and microstructure. The iron in ductile iron pipes is treated with magnesium, resulting in the formation of graphite nodules that give the material its ductile properties. This microstructure also provides a protective layer on the surface of the pipe, which helps to prevent corrosion. Additionally, ductile iron pipes have been used for several decades without the need for internal linings or coatings, proving their durability and resistance to corrosion. The smooth interior surface of ductile iron pipes also helps to minimize friction and maintain efficient flow rates. However, in certain cases where the conveyed fluid is highly corrosive or abrasive, or if the water quality is aggressive, internal linings or coatings may be recommended. These linings or coatings can be applied to protect the pipe from chemical attack or to prevent the leaching of iron into the water supply. Ultimately, the decision to use internal linings or coatings on ductile iron pipes depends on various factors such as the specific application, water quality, and local regulations. Consulting with professionals in the field, such as engineers or pipe manufacturers, can provide more tailored advice for specific scenarios.
- Q: What are the different methods for cutting ductile iron pipe?
- There are several different methods for cutting ductile iron pipe, depending on the specific requirements and constraints of the project. Some common methods include: 1. Manual Cutting: This method involves using a handheld saw or grinder with an abrasive cutting wheel to cut through the ductile iron pipe. It is a simple and relatively inexpensive method, but it can be labor-intensive and time-consuming for larger pipe sizes. 2. Mechanical Cutting: Mechanical cutting methods involve using specialized machinery to cut through the ductile iron pipe. This can include bandsaws, pipe cutters, or hydraulic cutting machines. These machines can provide faster and more precise cuts, especially for larger pipe sizes. However, they can be more expensive and require skilled operators. 3. Torch Cutting: Torch cutting, also known as oxyfuel cutting, involves using a torch to heat the ductile iron pipe and then introducing a high-pressure oxygen stream to create a chemical reaction that cuts through the metal. This method is effective for cutting thick-walled ductile iron pipe, but it can generate a significant amount of heat and sparks, requiring proper safety precautions. 4. Plasma Arc Cutting: Plasma arc cutting utilizes a high-velocity jet of ionized gas (plasma) to melt and cut through the ductile iron pipe. This method is ideal for cutting through thick-walled pipes where precision and efficiency are required. However, it can be more expensive and may require specialized equipment and training. 5. Waterjet Cutting: Waterjet cutting uses a high-pressure jet of water mixed with an abrasive material to cut through the ductile iron pipe. This method is highly precise and does not generate heat or sparks, making it suitable for cutting in sensitive environments. However, it can be slower and more expensive compared to other cutting methods. It is important to consider factors such as pipe size, project requirements, budget, and safety when selecting the appropriate method for cutting ductile iron pipe. Consulting with professionals or experts in the field can help determine the most suitable method for a specific project.
- Q: Are ductile iron pipes resistant to hydrogen sulfide corrosion?
- Yes, ductile iron pipes are resistant to hydrogen sulfide corrosion due to their high resistance to chemical corrosion and their protective inner lining that prevents contact between the pipe material and the corrosive elements.
- Q: Ductile iron pipes lined with cement mortar in the water (living water, water in the 6.9-7.3) in the early pH, why pH increased? How to solve this problem?
