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:Ductile iron gears are generally treated without heat treatment
Certainly. At the very least, the casting must be annealed and other heat treatment according to the requirement of use
Q:Can ductile iron pipes be used in potable water systems?
Ductile iron pipes are indeed suitable for use in potable water systems. They belong to the cast iron category but possess increased strength and ductility. Their durability, resistance to corrosion, and long lifespan make them a popular choice for water infrastructure, especially potable water systems. These pipes are produced in accordance with specific standards and regulations governing the use of potable water, ensuring the safe transportation of drinking water. Moreover, ductile iron pipes exhibit exceptional flow characteristics, making them well-suited for water distribution systems. All in all, ductile iron pipes are a dependable and frequently employed material in potable water systems.
Q:Are ductile iron pipes suitable for deep burial installations?
Yes, ductile iron pipes are suitable for deep burial installations. Ductile iron pipes have excellent strength and durability, making them ideal for underground applications. They can withstand the pressure and weight of the soil and any potential external forces. Additionally, ductile iron pipes have a high resistance to corrosion, which is crucial for long-term performance in buried environments. Their flexibility also allows them to withstand ground movements and settle without breaking. Overall, ductile iron pipes are a reliable and cost-effective choice for deep burial installations.
Q:Can ductile iron pipes be used for water supply in buildings?
Yes, ductile iron pipes can be used for water supply in buildings. Ductile iron pipes are known for their strength, durability, and corrosion resistance, making them suitable for carrying water in both residential and commercial structures. They have a long lifespan, high pressure rating, and can withstand various environmental conditions, making them a reliable choice for water distribution systems.
Q:What are the typical joint sealing requirements for ductile iron pipes under pressure?
The typical joint sealing requirements for ductile iron pipes under pressure include the use of rubber gaskets and mechanical joints. These joints are designed to provide a watertight seal and prevent any leakage or seepage of the pressurized fluid. Additionally, proper cleaning and lubrication of the joints before assembly is crucial to ensure a secure and effective seal. Regular inspection and maintenance are also necessary to identify and address any potential joint sealing issues.
Q:Are ductile iron pipes resistant to acid mine drainage corrosion?
Yes, ductile iron pipes are generally resistant to acid mine drainage (AMD) corrosion. Ductile iron is a highly durable material that has been widely used in various industries, including mining and water distribution, due to its excellent corrosion resistance properties. Acid mine drainage is a significant environmental problem that occurs when water comes into contact with sulfide minerals in mining areas, resulting in the formation of sulfuric acid. This acid can corrode and deteriorate various materials, including pipes, leading to infrastructure damage and water contamination. Ductile iron pipes have a protective layer formed by a cementitious lining, typically made of cement mortar or an epoxy coating. This lining acts as a barrier between the corrosive AMD and the pipe material, preventing direct contact and reducing the likelihood of corrosion. Furthermore, ductile iron pipes have a high resistance to both internal and external corrosion, making them well-suited for environments where acid mine drainage may be present. They have proven to be highly reliable and long-lasting even in harsh conditions, ensuring the continued integrity of the water distribution system and minimizing the potential for leaks or failures. However, it is important to note that the resistance of ductile iron pipes to acid mine drainage corrosion can also depend on several other factors, such as the specific composition and concentration of the AMD, the duration of exposure, and the temperature. Therefore, it is recommended to consult with experts and conduct proper material testing and analysis to ensure the suitability of ductile iron pipes in specific AMD environments.
Q:Are ductile iron pipes prone to leakage?
Ductile iron pipes are generally resistant to leakage due to their robust and durable nature. However, like any other infrastructure, they can be susceptible to leakage if they are not properly installed or maintained. Regular inspections, proper installation techniques, and timely repairs are essential to minimize the risk of leakage in ductile iron pipes.
Q:What is the expected sound attenuation of ductile iron pipes?
Several factors can affect the expected sound attenuation of ductile iron pipes. Generally, these pipes have good sound attenuation properties due to their dense construction and thick walls. The density of the material helps absorb and dampen sound waves, reducing noise transmission. Additionally, the thickness of the pipe walls adds an extra barrier for sound to pass through, contributing to sound attenuation. However, it's important to consider other factors that can influence the specific sound attenuation of ductile iron pipes. These factors include pipe diameter, wall thickness, installation method, and the surrounding environment. For example, larger diameter pipes may have slightly lower sound attenuation compared to smaller diameter pipes due to their increased surface area. Additionally, variations in wall thickness can affect the sound insulation properties. During installation, the presence of joints or fittings in the pipeline can create points where sound can transmit, reducing sound attenuation. Therefore, it is recommended to use proper installation techniques that minimize the use of joints and fittings to enhance sound attenuation. The surrounding environment also plays a role in sound attenuation. For instance, if the pipes are buried in soil, the composition and density of the soil can affect sound transmission properties. Moreover, the presence of other structures or materials nearby may influence the overall sound attenuation performance. To determine the specific expected sound attenuation of ductile iron pipes for a particular application, it is advisable to consult manufacturer specifications or seek assistance from acoustic engineering professionals. They can consider all relevant factors and conduct specific tests or simulations to provide accurate predictions.
Q:Can ductile iron pipes be used for underground drainage systems?
Indeed, underground drainage systems can utilize ductile iron pipes. Ductile iron, being a robust and enduring substance, exhibits resistance to corrosion, rendering it appropriate for subterranean applications. Possessing remarkable tensile strength, it can endure substantial loads and pressures, thereby making it an excellent choice for drainage systems that encounter significant flow rates or necessitate substantial burial depths. Moreover, ductile iron pipes boast an extended lifespan, thereby decreasing the requirement for frequent maintenance or replacement. All in all, ductile iron pipes prove to be an unwavering and efficient option for underground drainage systems.
Q:Can ductile iron pipes be used for gas distribution systems?
Yes, ductile iron pipes can be used for gas distribution systems. Ductile iron pipes are known for their strength and durability, making them suitable for carrying various types of fluids, including natural gas. These pipes have excellent corrosion resistance and can withstand the high pressure and stress typically associated with gas distribution systems. Additionally, ductile iron pipes are cost-effective and have a long lifespan, making them a reliable choice for gas distribution networks.
