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 is the minimum cover requirement for ductile iron pipes?
The specific project or engineering design considerations typically determine the minimum cover requirement for ductile iron pipes. However, as a general rule, it is often recommended to have a minimum cover requirement of at least 2 feet (or 0.6 meters) from the top of the pipe to the finished ground surface. This recommendation helps protect the pipe from external loads, soil settlement, and potential damage during construction activities. Additionally, it contributes to the long-term structural integrity and durability of the ductile iron pipe system. It is crucial to consult local building codes, industry standards, and project specifications for accurate and up-to-date information on specific minimum cover requirements.
Q:Can ductile iron pipes be used for bridge crossings?
Ductile iron pipes are indeed suitable for bridge crossings. This material is widely used in various applications, such as water and wastewater systems, due to its strength and durability. When it comes to bridge crossings, ductile iron pipes offer numerous advantages. They possess high tensile strength, enabling them to handle the load and stress imposed by the bridge structure. In addition, they are highly resistant to corrosion, making them well-suited for environments where bridges may be exposed to moisture and other harsh conditions. Moreover, ductile iron pipes have the capability to withstand seismic activity, making them a dependable choice for areas prone to earthquakes. Overall, ductile iron pipes are a reliable and appropriate option for bridge crossings due to their strength, durability, resistance to corrosion, and ability to withstand seismic activity.
Q:What is the ductile cast iron pipe
Cast iron pipe is called a coiled pipe, one is the mouth, and the other is the flange. It is often used in the joint of the cast iron pipe valve, and is often used in conjunction with the second pipe (plug pipe coil)
Q:What are the different pressure classes available for ductile iron pipes?
Ductile iron pipes come in various pressure classes that are commonly used for water and wastewater purposes. These pressure classes, namely Class 150, Class 200, Class 250, Class 300, and Class 350, indicate the maximum pressure in psi that the pipes can withstand. For instance, Class 150 pipes have a maximum working pressure of 150 psi, while Class 200 pipes can handle up to 200 psi. Class 250 pipes can withstand pressures up to 250 psi, and Class 300 pipes have a maximum working pressure of 300 psi. Lastly, the highest pressure class, Class 350, can handle pressures up to 350 psi. The selection of the appropriate pressure class for a ductile iron pipe depends on several factors, including system design, fluid characteristics, and operating conditions. To determine the suitable pressure class for a specific application, it is crucial to consult relevant standards and guidelines, such as those provided by the American Water Works Association (AWWA). It is important to note that these pressure classes refer to the working pressure of the pipe, which is the pressure the pipe is designed to safely contain during normal operation. To ensure compliance with the required pressure class standards, the pipes are typically tested and certified.
Q:Can ductile iron pipes be used in gravity sewer systems?
Yes, ductile iron pipes can be used in gravity sewer systems. Ductile iron is a strong and durable material that is commonly used in various applications, including sewer systems. It has excellent resistance to corrosion and can withstand high pressure and heavy loads. Additionally, ductile iron pipes have a smooth interior surface, which helps to reduce friction and improve the flow of waste and wastewater. Therefore, they are a suitable choice for gravity sewer systems, where the flow of sewage relies on gravity to move through the pipes.
Q:Can ductile iron pipe be used in areas with high groundwater levels?
Areas with high groundwater levels can indeed utilize ductile iron pipe. This type of pipe is renowned for its robustness and sturdiness, which renders it appropriate for a wide range of purposes, including areas with high groundwater levels. Its resistance to corrosion ensures that it remains highly impervious to the damaging impact of groundwater, thereby guaranteeing enduring efficiency and dependability. Furthermore, the flexible joints of ductile iron pipe enable it to endure ground shifts and settlements caused by fluctuating groundwater levels. As a result, it represents a suitable choice for regions with high groundwater levels, offering a dependable solution for water distribution systems and other subterranean applications.
Q:What are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Because of differences in depth and soil properties, the excavation width is differentUsually to ensure that the width of bottom surface on both sides of the 600 1400+ manual operation. (such a large pipe flange bolt, the tool is not easy to expand, so the need for manual operation. So wide)
Q:Can ductile iron pipes be used for underwater installations?
Yes, ductile iron pipes can be used for underwater installations. Ductile iron is a strong and durable material that is resistant to corrosion, making it suitable for submerged applications. Additionally, ductile iron pipes have excellent joint integrity, ensuring water-tightness even under high hydrostatic pressure. The pipes are often coated with protective linings and coatings to further enhance their resistance to corrosion and extend their lifespan in underwater environments. Overall, ductile iron pipes are a reliable choice for underwater installations due to their strength, durability, and corrosion resistance properties.
Q:Can ductile iron pipes be used for both water and sewage systems?
Ductile iron pipes can serve for both water and sewage systems, owing to their remarkable strength and durability. Renowned for their exceptional mechanical properties, these pipes can endure the immense pressure and stress encountered in such systems. Furthermore, their resistance to corrosion renders them optimal for transporting both clean water and sewage. Consequently, ductile iron pipes emerge as a dependable and adaptable option for water and sewage systems, given their wide-ranging applications.
