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 requirements for the hydrostatic test of ductile iron pipes?: The pipe work pressure P is less than 0.5MPa, the test pressure is 2P, the pipe work pressure is greater than 0.5MPa, the test pressure is P+0.5. After the water pressure rises to the test pressure, the pressure is fixed for 10 minutes, and the pipe joint and the pipe body are not damaged and leaked.

Q:What is the expected corrosion rate of ductile iron pipes?: The expected corrosion rate of ductile iron pipes can vary depending on several factors, including the specific environment in which the pipes are installed, the pH and composition of the water or soil they come into contact with, and the presence of any corrosive substances or chemicals. In general, ductile iron pipes are known for their excellent resistance to corrosion compared to other materials such as cast iron or steel. This is due to the presence of a protective layer called a passive film, which forms naturally on the surface of the pipes when exposed to oxygen in the environment. This passive film acts as a barrier, preventing further corrosion from occurring. However, it is important to note that even ductile iron pipes can experience some level of corrosion over time, especially in aggressive or highly corrosive environments. The expected corrosion rate can range from very low to moderate, depending on the aforementioned factors. To ensure the longevity and performance of ductile iron pipes, it is recommended to implement proper maintenance and monitoring practices. This includes regular inspections, cleaning, and the application of protective coatings or linings when necessary. Additionally, implementing a cathodic protection system can further enhance the corrosion resistance of the pipes. Ultimately, it is important to consult with experts and professionals in the field of corrosion and pipe materials to accurately determine the expected corrosion rate of ductile iron pipes in a specific application or environment.

Q:How are ductile iron pipes protected against interior corrosion?: Cement mortar lining is utilized to protect ductile iron pipes against interior corrosion. This process involves the application of a layer of cement mortar to the inner surface of the pipe. By acting as a protective barrier, the cement mortar prevents the corrosive elements in the water or fluid from directly contacting the iron material. To apply the cement mortar lining, the interior surface of the ductile iron pipe is initially prepared by removing any loose scale or debris. Next, a mixture of cement, sand, and water is prepared to create a paste-like consistency. Skilled workers can then manually apply this mixture to the interior surface of the pipe or use a spinning machine. Once the cement mortar lining is applied, it must cure for a specific period, typically around 24 hours. During this curing process, the cement mortar hardens and forms a dense protective layer on the pipe's inner surface. The cement mortar lining provides several advantages in safeguarding ductile iron pipes against corrosion. It creates a smooth and continuous surface that prevents direct contact between the water or fluid and the iron material, thus reducing the risk of corrosion. Additionally, the lining helps to minimize friction within the pipe, thereby enhancing flow efficiency. It is crucial to regularly inspect and maintain the cement mortar lining to ensure its effectiveness in preventing corrosion. Over time, the lining may develop cracks or deteriorate, compromising its protective properties. Therefore, periodic inspections are necessary to repair or replace the lining as required, ensuring the integrity of the ductile iron pipes and preventing interior corrosion.

Q:What is the typical diameter range of ductile iron pipes?: The typical diameter range of ductile iron pipes varies depending on the specific application and industry standards. Generally, ductile iron pipes come in a wide range of diameters to accommodate various needs. In water distribution systems, the typical diameter range can vary from as small as 3 inches (76 mm) to as large as 64 inches (1626 mm) or even larger. For sewer and wastewater systems, the typical diameter range is usually between 4 inches (102 mm) to 48 inches (1219 mm). However, it is important to note that these ranges are not exhaustive and there may be instances where ductile iron pipes are available in sizes outside of these common ranges. It is always advisable to consult industry standards and specific project requirements to determine the appropriate diameter range for ductile iron pipes.

Q:Are ductile iron pipes suitable for trenchless pipe ramming installations?: Yes, ductile iron pipes are suitable for trenchless pipe ramming installations. They possess the necessary strength and flexibility to withstand the impact and vibrations caused during the ramming process. Additionally, their corrosion resistance and durability make them a reliable choice for trenchless installations, ensuring long-term performance and minimal maintenance requirements.

Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?: In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel.

Q:Can ductile iron pipes be used for water supply networks?: Yes, ductile iron pipes can be used for water supply networks. Ductile iron pipes are known for their strength and durability, making them suitable for carrying water over long distances. They are resistant to corrosion and can withstand high pressure and external loads, making them a reliable choice for water supply systems. Additionally, ductile iron pipes have a smooth internal surface, which reduces friction and allows for efficient water flow. Overall, ductile iron pipes have been widely used in water supply networks around the world due to their excellent performance and longevity.

Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?: The situation in use abroad seems. It is considered that the corrosion of the inner wall of the centrifugal centrifugal ductile iron pipe and the rupture of the pipe are easy to occur when the content of chloride ion exceeds 5O0PPm in the pipe laying environment. This is mainly because, because the cement paste protection layer is the late spraying construction, it is not good to combine with the prefabricated core tube. It often causes water or moisture to seep in and causes oxidation and corrosion of the prestressing steel bars, resulting in fracture. The adhesive interface between cement mortar and centrifugally cast iron pipe is not reasonable. Because of the water absorption of cement, when the water enters the pipe, it is easy to destroy the interface and corroded the inner wall of the centrifugally cast iron pipe. Because it is a brittle material, it is easy to cause sudden accidents.

Q:How do ductile iron pipes handle water velocity?: Due to their unique mechanical properties, ductile iron pipes are well-suited for managing water velocity. Ductile iron, being a highly durable and strong material, can endure high water velocities without significant damage or deformation. The inherent ductility of the pipe enables it to absorb the energy generated by the flowing water, effectively reducing the risk of pipe failure or bursting. This characteristic makes ductile iron pipes suitable for handling high-pressure water flow, making them an ideal choice in situations where water velocity is a concern. Furthermore, the smooth internal surface of ductile iron pipes promotes efficient water flow and minimizes friction losses. This smoothness reduces resistance encountered by the water as it moves through the pipe, allowing for higher water velocities without compromising the pipe's integrity. Moreover, ductile iron pipes can be manufactured in various sizes and thicknesses, providing customization options based on specific water velocity requirements. This flexibility ensures that ductile iron pipes can effectively manage a wide range of water velocities, from low-flow applications to high-velocity scenarios. In conclusion, ductile iron pipes possess exceptional capabilities when it comes to handling water velocity. Their strength, ductility, and smooth internal surface contribute to their ability to withstand high water velocities without compromising their structural integrity, making them a dependable choice for water distribution systems.

Q:What are the different corrosion protection options for ductile iron pipe?: There are several corrosion protection options available for ductile iron pipe to ensure its longevity and durability. These options include: 1. Cement Mortar Lining: This involves coating the inner surface of the pipe with a layer of cement mortar, which acts as a barrier between the pipe and corrosive elements in the water or soil. Cement mortar lining provides excellent corrosion resistance and can last for several decades. 2. Polyethylene Encasement: This method involves wrapping the ductile iron pipe with a layer of polyethylene material. The polyethylene acts as a physical barrier, protecting the pipe from external corrosive elements. Polyethylene encasement is commonly used in aggressive soil conditions and can offer long-lasting protection. 3. Internal and External Coatings: Various types of coatings can be applied to the inner and outer surfaces of the ductile iron pipe to provide corrosion resistance. These coatings can be epoxy, polyurethane, or fusion-bonded epoxy (FBE) coatings. These coatings create a barrier between the pipe and the surrounding environment, preventing corrosion. 4. Cathodic Protection: This method involves using an electrical current to protect the pipe from corrosion. Cathodic protection systems can be either galvanic (sacrificial anode) or impressed current systems. These systems direct the flow of electrons to prevent the oxidation of the ductile iron pipe. 5. Zinc Coating: Zinc coating, also known as galvanizing, involves applying a layer of zinc to the surface of the ductile iron pipe. The zinc acts as a sacrificial anode, corroding instead of the iron pipe. Zinc coating provides effective corrosion protection, particularly in soil conditions with low resistivity. It's important to note that the choice of corrosion protection option for ductile iron pipes depends on various factors such as the environment, water chemistry, soil conditions, and expected service life. Consulting with corrosion protection specialists and engineers can help in selecting the most suitable option for specific applications.
