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:
Indeed, underground applications can employ ductile iron pipe. Renowned for its robustness and endurance, ductile iron pipe proves to be well-suited for a multitude of underground uses, including water and sewage systems, gas pipelines, and irrigation systems. Its exceptional resistance to corrosion and external burdens renders it a dependable selection for underground installations, where sustained functionality and structural soundness are pivotal considerations. Moreover, ductile iron pipe's pliability enables it to endure ground shifting and settling sans fracturing or shattering, making it an apt choice for regions susceptible to seismic occurrences.
Q:What are the lubricants for the installation of ductile iron pipes for tap water?
When choosing lubricant, it is necessary to consider the movement of friction pairs, materials, surface roughness, working environment and working conditions, as well as the performance of lubricants. In mechanical equipment, lubricants are mostly distributed by lubrication to the parts that need lubrication.
Q:
The expected external coating for ductile iron pipes is typically a protective layer of asphaltic or polyethylene coating.
Q:
Yes, ductile iron pipes can be used in areas with high soil acidity. Ductile iron is highly resistant to corrosion, including the effects of soil acidity, making it a suitable choice for such environments.
Q:
Yes, ductile iron pipes are suitable for use in irrigation gate systems. Ductile iron is a type of cast iron that has enhanced strength and flexibility, making it a durable and reliable choice for applications such as irrigation gate systems. Ductile iron pipes are known for their high tensile strength and resistance to corrosion, which is important for maintaining the integrity of the irrigation system. Additionally, ductile iron pipes have the ability to withstand high pressure and provide a long service life, making them a cost-effective solution for irrigation gate systems. Overall, ductile iron pipes are well-suited for use in irrigation gate systems due to their strength, durability, and resistance to corrosion.
Q:How much pressure can the ductile iron pipe socket meet?
After all, he is not steel, strength is low, toughness is poor. But a short period of about 100kg, things should be no problem.
Q:
There are several different types of joints that can be used with ductile iron pipe. These joints are designed to provide a secure and watertight connection between sections of pipe. Some of the most common types of joints used with ductile iron pipe include: 1. Mechanical Joint: This is the most commonly used joint for ductile iron pipe. It consists of a gland and a follower which are tightened using bolts and nuts to provide a tight seal. Mechanical joints are flexible and can accommodate slight misalignments. 2. Push-On Joint: This type of joint does not require any bolts or nuts. It is designed to be easily assembled by simply pushing the pipe sections together. A rubber gasket is used to provide a watertight seal. 3. Restrained Joint: Restrained joints are specifically designed for applications where pipe movement needs to be limited. These joints typically include a mechanical joint with additional features such as thrust collars or tie rods to prevent axial movement. 4. Flanged Joint: Flanged joints are commonly used for larger diameter pipes. The pipe ends are flanged and then bolted together, with a gasket placed in between to create a leak-proof connection. Flanged joints are typically used in applications where frequent disassembly and reassembly may be required. 5. Welded Joint: In some cases, ductile iron pipe sections may be welded together using a fusion welding process. This creates a permanent and strong joint. Welded joints are commonly used in high-pressure applications where a reliable and durable connection is required. It is important to note that the choice of joint type will depend on the specific requirements of the project, such as the pipe diameter, pressure rating, and the nature of the fluid being transported. Additionally, local regulations and standards may also dictate the type of joint that should be used in certain applications.
Q:
Ductile iron pipes are suitable for use in areas prone to earthquakes. This material, known for its strength and flexibility, can withstand the movement and vibrations caused by seismic activity. Its exceptional ductility means it can deform under stress without fracturing or breaking. Consequently, ductile iron pipes are capable of absorbing the energy produced during an earthquake, minimizing the risk of pipe failure or rupture. Moreover, these pipes have a proven track record in seismic zones, attesting to their resilience and dependability in such regions. Nevertheless, it is crucial to emphasize the importance of proper installation and design considerations, including the use of appropriate jointing methods and ensuring adequate anchoring. These factors are crucial to guarantee the optimal performance of ductile iron pipes in earthquake-prone areas.
Q:How to properly maintain FRP pipes
The wall of the pipe is smoothReduce flow resistance, increase flow speed and reduce energy consumption. Compared with the same size steel pipe, the flow rate of the same volume can be increased by about 10%, and no fouling and long-term use can not reduce the flow rate. The protection of cables in interference and heavy corrosion environment is better.
Q:The difference between ductile iron pipe and steel pipe used in pipe jacking
Comparison between ductile iron pipe and universal cast iron pipe: the process of making ductile iron pipe is cast by adding alkaline earth metal or rare metal such as magnesium and calcium in the raw material of common cast iron pipe.
