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: Can ductile iron pipes be used in high-pressure applications?
Yes, ductile iron pipes can be used in high-pressure applications. Ductile iron has excellent mechanical properties and high tensile strength, making it suitable for withstanding high-pressure conditions. Its inherent toughness and durability allow it to handle the stress and pressure exerted on the pipes, making it a reliable choice for various high-pressure applications.
Q: Are ductile iron pipes resistant to root intrusion?
Although ductile iron pipes typically show resistance to root intrusion, they are not completely impervious. Despite the strength and durability of the material, root intrusion can still happen if there are any cracks, joints, or damaged parts in the pipes. It should be emphasized that root intrusion tends to occur more frequently in older or inadequately maintained pipes, where cracks or gaps may eventually form. However, modern ductile iron pipes are frequently coated with protective layers or linings to decrease the likelihood of root intrusion. Moreover, regular inspection and maintenance can aid in identifying and resolving potential problems before they become more serious.
Q: How does ductile iron pipe perform in areas with high soil erosion?
Ductile iron pipe is known for its exceptional strength and durability, making it a reliable choice for areas with high soil erosion. Its unique composition, which includes graphite nodules, allows it to be both flexible and resistant to fractures or cracks, even in challenging environments. This makes ductile iron pipe highly capable of withstanding the impact of soil erosion. In areas with high soil erosion, the soil particles can scrape against the surface of the pipe, potentially causing abrasions or damage. However, ductile iron pipe's thick wall thickness and corrosion-resistant coating provide an effective barrier against these abrasive forces. This means that even in areas with significant soil erosion, ductile iron pipe can maintain its structural integrity and functionality. Moreover, ductile iron pipe's ability to resist corrosion further enhances its performance in areas with high soil erosion. Soil erosion often leads to an increased presence of moisture, which can accelerate the corrosion process of certain materials. However, ductile iron pipe's protective coating, typically made from zinc or epoxy, acts as a shield against corrosion, ensuring its long-term performance and reliability. In summary, ductile iron pipe demonstrates excellent performance in areas with high soil erosion due to its strength, flexibility, and resistance to fractures or cracks. Its thick wall thickness and corrosion-resistant coating make it highly durable against abrasive forces and corrosion, allowing it to withstand the challenges posed by soil erosion. As a result, ductile iron pipe is a dependable choice for infrastructure projects in such areas, providing long-lasting and efficient water and wastewater transportation systems.
Q: How are ductile iron pipes joined to fittings and valves?
Ductile iron pipes are typically joined to fittings and valves through a process known as flanged connection or mechanical joint. Flanged connections involve the use of flanges, which are circular discs with evenly spaced holes around the perimeter. These flanges are bolted together, creating a tight seal between the pipe and the fitting or valve. To join a ductile iron pipe to a fitting or valve using a flanged connection, the pipe end is first prepared by cleaning and deburring any rough edges. A gasket made of rubber or other suitable material is then placed between the pipe end and the flange face. The flange is aligned with the pipe, and bolts are inserted through the holes in the flange, passing through corresponding holes in the fitting or valve. Once all the bolts are in place, they are tightened evenly, gradually applying pressure to compress the gasket and create a secure and leak-proof seal. To ensure proper alignment and sealing, tightening the bolts is typically done in a specific pattern or sequence. Alternatively, ductile iron pipes can also be joined to fittings and valves using mechanical joints. This involves the use of a rubber gasket or gland that is inserted into a groove on the pipe end. The fitting or valve also has a corresponding groove, and when the two are brought together, the gasket is compressed, creating a tight seal. Mechanical joints offer some flexibility, allowing for slight movement or expansion and contraction of the pipe. This can be beneficial in applications where there may be thermal variations or ground movement, reducing the risk of pipe failure. Both flanged connections and mechanical joints are widely used in various industries and applications that require the joining of ductile iron pipes to fittings and valves. The choice of joining method depends on factors such as the specific application, pipe size, pressure requirements, and local codes and regulations.
Q: What are the typical maintenance requirements for ductile iron pipe?
To maintain ductile iron pipe, it is necessary to conduct regular inspections, clean the pipe, and repair any damage. Inspections play a crucial role in identifying signs of damage, corrosion, or leaks. This can be done visually or using non-destructive testing techniques such as ultrasonic or magnetic particle testing. Regular inspections are important for detecting and addressing issues before they worsen and cause significant damage. Cleaning is another essential maintenance requirement for ductile iron pipe. Over time, sediment, scale, and debris can accumulate inside the pipe, reducing its flow capacity and potentially causing blockages. Regular cleaning methods like high-pressure water jetting or mechanical cleaning can remove these deposits, ensuring optimal flow and preventing problems related to reduced flow or pressure. Repairing any damage or corrosion is crucial for maintaining ductile iron pipe. If cracks, leaks, or other forms of damage are detected during inspections, prompt repairs are necessary to prevent further deterioration and potential failure. Depending on the extent of the damage, repairs may include welding, epoxy lining, or replacement of the affected section of the pipe. In addition to these specific maintenance requirements, implementing a comprehensive maintenance program is important. This may involve preventative measures such as cathodic protection to prevent corrosion or the application of protective coatings to extend the pipe's lifespan. Overall, regular inspections, cleaning, and repairs are necessary for maintaining ductile iron pipe. Following these maintenance practices ensures the pipe's longevity, reliability, and optimal performance, reducing the risk of failures and disruptions.
Q: If the ductile iron pipe is broken, can we use rush repair?
In this way, manpower, material resources and financial resources can be saved, time can be saved, and unnecessary troubles to the citizens' water supply can also be reduced.
Q: What kind of valves are commonly used in ductile iron pipes?
You ask the ductile cast iron valves used on no special, because this interface in connection with the valve on the pipe flange is basically, as long as the flange of the valve should be can be used in milling pipe.
Q: Can ductile iron pipes be used for underground hydropower systems?
