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 areas with high levels of hydrogen sulfide gas?: Ductile iron pipes can generally be used in areas with high levels of hydrogen sulfide gas, but it is important to consider certain factors before making a decision. Hydrogen sulfide gas is corrosive and can potentially cause damage to metal pipes over time. While ductile iron is known for its durability and corrosion resistance, prolonged exposure to high levels of hydrogen sulfide gas can still lead to corrosion and deterioration. To mitigate the risks associated with hydrogen sulfide gas, it is advisable to assess the specific conditions of the area beforehand. This includes conducting a comprehensive analysis of the hydrogen sulfide gas concentration, pH levels, temperature, and other factors that may influence corrosion. Consulting with experts or engineering professionals who specialize in corrosion control can provide valuable insights and guidance. In some cases, additional measures may be necessary to protect ductile iron pipes. Coating the interior and exterior surfaces of the pipes with protective materials, such as epoxy or polyethylene, can provide an extra layer of defense against corrosion. Alternatively, cathodic protection systems can be employed to protect the pipes by applying a low voltage electrical current that mitigates the corrosion process. Ultimately, the decision to use ductile iron pipes in areas with high levels of hydrogen sulfide gas should be based on a thorough understanding of the specific conditions and implementing appropriate corrosion prevention measures. Regular monitoring and maintenance should also be conducted to ensure the pipes are functioning optimally and to address any potential issues before they escalate.

Q:Can ductile iron pipes be used in potable water systems?: Yes, ductile iron pipes can be used in potable water systems. Ductile iron is a suitable material for water distribution systems as it has excellent durability, strength, and corrosion resistance. It is commonly used in potable water systems due to its ability to withstand high water pressure and its long service life. Additionally, ductile iron pipes are also approved by various national and international standards for use in potable water applications.

Q:How are ductile iron pipes protected against stray current corrosion?: Various preventive measures and protective coatings are employed to safeguard ductile iron pipes from stray current corrosion. Stray current corrosion arises when an electric current flows through the pipe, causing accelerated corrosion and potential harm. To prevent this, the following measures are generally utilized: 1. Electrical isolation: Ductile iron pipes are insulated from other metallic structures by means of insulating materials like rubber gaskets or non-conductive coatings. This insulation obstructs the passage of stray current through the pipe, thereby minimizing the risk of corrosion. 2. Cathodic protection: Cathodic protection is a widely employed technique to shield ductile iron pipes from stray current corrosion. It involves installing sacrificial anodes or impressed current systems near the pipe. These anodes or systems emit a controlled electric current that counters the stray current and guarantees the cathodic protection of the iron pipe. 3. Coatings: Ductile iron pipes are typically coated with protective layers to enhance their resistance against corrosion. A common coating is fusion-bonded epoxy (FBE), which offers a high level of protection against stray current corrosion. FBE coatings act as a barrier, preventing electrical contact between the pipe and the surrounding environment. 4. Monitoring and maintenance: Regular monitoring and maintenance are essential for ensuring the ongoing protection of ductile iron pipes against stray current corrosion. This entails inspecting the protective coatings for any damage or deterioration and promptly repairing or replacing them as required. Additionally, monitoring systems can be installed to detect and measure stray currents, allowing for timely intervention if necessary. By implementing these protection measures, ductile iron pipes can effectively ward off stray current corrosion, thereby prolonging their lifespan and ensuring the integrity of the pipeline infrastructure.

Q:Usage of ductile iron pipe expander: Usage of ductile iron pipe expander:1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.2, the expansion of the inner sleeve should be noted that the direction of the inner sleeve is consistent with the direction of the medium flow. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.3, the need for "cold tight" expansion device, pre deformation of the auxiliary components should be installed in the pipeline before they can be removed.4, it is strictly prohibited to use telescopic deformation method to adjust the installation of the pipe, so as not to affect the normal function of the telescopic device, reduce the service life and increase the piping, equipment and supporting components of the load.5 、 during installation, welding slag is not allowed to splash to the surface of wave shell, and the wave shell is not allowed to suffer other mechanical damage.6, pipe installation is completed, should be removed as soon as the wave expansion device used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.

Q:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?: The pipe material does not determine the valve material, the valve is generally based on several pressure temperature rating, medium condition and velocity, the valve must play a role as valve material, such as wear resistance, corrosion resistance, and so on,

Q:How does ductile iron pipe perform in corrosive soils?: Ductile iron pipe performs exceptionally well in corrosive soils due to its unique composition and protective lining. The iron in ductile iron pipe is more resistant to corrosion than other materials, such as steel. Additionally, the interior of the pipe is often lined with cement mortar or an epoxy coating, providing an extra layer of protection against corrosive elements. This combination of materials enables ductile iron pipe to withstand the effects of corrosive soils and maintain its structural integrity over an extended period of time.

Q:What is the difference between flexible joint mechanism and seismic cast iron pipe DN100 and ductile iron pipe?: Nodular cast iron has high strength and strong plasticity. The tensile strength of ductile iron is twice that of gray iron, and the yield strength even exceeds that of cast steel.

Q:Can ductile iron pipe be used for cooling water systems?: Yes, ductile iron pipe can be used for cooling water systems. Ductile iron pipes are known for their high strength and durability, making them suitable for various applications, including cooling water systems. They have excellent resistance to corrosion, which is important in preventing damage and maintaining the efficiency of the cooling water system. Additionally, ductile iron pipes can handle high-pressure and high-temperature conditions, making them a reliable choice for this purpose.

Q:Are ductile iron pipes suitable for industrial water systems?: Yes, ductile iron pipes are suitable for industrial water systems. They possess excellent strength, durability, and corrosion resistance, making them ideal for transporting water in industrial settings. Additionally, their ductility allows them to withstand high pressure and accommodate for ground movement, ensuring long-term reliability in industrial water systems.

Q:What material is the cutting tool for ductile iron?: With pleasure. If necessary, you can also describe your processing work and so on, I help you analyze, recommend a few corresponding knives to you.
