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 difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
- The front is the material grade, and the back of the A should have special requirements.
- Q: Are ductile iron pipes suitable for use in irrigation sprinkler systems?
- Ductile iron pipes, known for their durability, strength, and corrosion resistance, are a suitable option for irrigation sprinkler systems. With their high tensile strength, they can withstand heavy loads and high pressure, ensuring a consistent water supply. Moreover, their long lifespan reduces the frequency of maintenance and replacement, making them cost-effective. In summary, ductile iron pipes are reliable and appropriate for use in irrigation sprinkler systems.
- Q: What are the typical lengths of ductile iron pipes?
- The specific project requirements and industry standards play a significant role in determining the typical lengths of ductile iron pipes. Generally, ductile iron pipes are commonly available in lengths ranging from 18 feet (5.5 meters) to 20 feet (6 meters). These lengths are well-suited for a variety of applications including water distribution, wastewater systems, and industrial pipelines. It is worth mentioning that custom lengths can also be produced to fulfill specific project requirements.
- Q: Are ductile iron pipes resistant to seismic events?
- Yes, ductile iron pipes are resistant to seismic events. Ductile iron has excellent strength and flexibility, allowing it to withstand ground movement during earthquakes without fracturing or failing. This makes it a reliable choice for underground infrastructure in areas prone to seismic activity.
- Q: Can ductile iron pipes be used for wastewater pumping stations?
- Indeed, wastewater pumping stations can utilize ductile iron pipes. With their remarkable strength and durability, ductile iron pipes are well-suited for transporting wastewater and effectively managing the immense pressures and corrosive properties of sewage. Furthermore, the smooth interior surface of ductile iron pipes prevents blockages and facilitates the efficient flow of wastewater. Moreover, these pipes exhibit resistance towards external forces like soil displacement or heavy vehicular movement, thereby establishing themselves as a dependable option for wastewater pumping stations.
- Q: What are the different joint types available for ductile iron pipe?
- Ductile iron pipes offer a range of joint types, each with its own benefits and uses. The most commonly employed joint types in ductile iron pipe installations include: 1. Push-on Joint: This type involves inserting a rubber gasket into a groove on the pipe's spigot end. The pipe is then pushed into the bell end of the adjacent pipe, creating a watertight seal. Push-on joints are known for their quick and easy installation, making them perfect for applications that require efficiency. 2. Mechanical Joint: This joint relies on a gland and follower gasket, which are compressed between the spigot end of one pipe and the bell end of another. Bolts and nuts are used to secure the joint, ensuring a tight and secure connection. Mechanical joints provide excellent integrity and are used in applications with higher pressures or heavy loads. 3. Flanged Joint: Flanged joints utilize flanges on the pipe ends, which are bolted together with gaskets to achieve a leak-proof connection. These joints are commonly employed in situations where pipes need to be easily disconnected and reconnected, such as pump stations or valve connections. 4. Restrained Joint: These joints are specifically designed to prevent pipes from separating under high internal pressures or external forces. They typically incorporate mechanical joints with additional restraining devices like harnesses, rods, or thrust blocks. Restrained joints are commonly used in applications where pipe movement poses a risk or stability is crucial. It is important to consider factors like the application, operating conditions, and project requirements when selecting a joint type. Consulting a professional engineer or pipe manufacturer is advisable to ensure the most suitable joint type is chosen for a specific ductile iron pipe installation.
- Q: Deep well spiral iron pipe, or ductile iron tube?
- In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
- Q: How does ductile iron pipe perform in areas with high groundwater salinity?
- Ductile iron pipe performs well in areas with high groundwater salinity due to its inherent corrosion resistance properties. The high levels of salinity in the groundwater can cause corrosion and deterioration of certain materials, but ductile iron is highly resistant to this type of corrosion. Its composition and manufacturing process make it less susceptible to damage from corrosive elements, such as salt and minerals present in high salinity water. The corrosion resistance of ductile iron pipe is primarily attributed to its protective iron oxide coating, which forms naturally on the interior and exterior surfaces of the pipe. This coating acts as a barrier, preventing direct contact between the pipe and the corrosive elements in the groundwater. Additionally, ductile iron pipes are often lined with cement mortar or a protective epoxy coating, which further enhances their resistance to corrosion and provides an additional layer of protection. Furthermore, ductile iron pipe has a long lifespan, often exceeding 100 years, which makes it ideal for areas with high groundwater salinity. Its durability and resistance to corrosion ensure that it can withstand the harsh conditions associated with high salinity environments, minimizing the need for frequent repairs or replacements. In summary, ductile iron pipe is an excellent choice for areas with high groundwater salinity due to its corrosion resistance properties. Its protective iron oxide coating, coupled with optional linings, provides a reliable and long-lasting solution, ensuring the integrity and performance of the pipe system even in challenging environments.
- Q: What is the expected corrosion rate of ductile iron pipes?
- Several factors can influence the expected corrosion rate of ductile iron pipes, including the specific environment in which they 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. Compared to materials like cast iron or steel, ductile iron pipes are well-known for their excellent resistance to corrosion. This is because they naturally develop a protective layer called a passive film on their surface when exposed to oxygen in the environment. This passive film acts as a barrier, preventing further corrosion. However, it is important to acknowledge that even ductile iron pipes can experience some degree of corrosion over time, especially in aggressive or highly corrosive environments. The expected corrosion rate can vary from very low to moderate, depending on the aforementioned factors. To ensure the durability and performance of ductile iron pipes, it is advisable to follow proper maintenance and monitoring practices. This includes regular inspections, cleaning, and the application of protective coatings or linings when necessary. Furthermore, implementing a cathodic protection system can further enhance the pipes' corrosion resistance. Ultimately, consulting experts and professionals in the field of corrosion and pipe materials is crucial for accurately determining the expected corrosion rate of ductile iron pipes in a specific application or environment.
- Q: Classification of cast iron pipes
- Sand casting centrifugal cast iron pipe:The sand casting centrifugal cast iron pipe is made of gray cast iron. It is suitable for the transportation of pressure water such as water and gas.
