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: Are ductile iron pipes suitable for use in paper mills?
Yes, ductile iron pipes are suitable for use in paper mills. Ductile iron is known for its high strength and durability, making it an excellent choice for various industrial applications, including paper mills. These pipes can withstand high-pressure systems and are resistant to corrosion, making them suitable for transporting water, chemicals, and other fluids commonly used in paper mills. Additionally, ductile iron pipes have good impact resistance, which is beneficial in an environment where heavy machinery and equipment are often present. Overall, ductile iron pipes are a reliable and long-lasting option for paper mills due to their strength, durability, corrosion resistance, and ability to handle high-pressure systems.
Q: What are the different joint restraint systems available for ductile iron pipe?
Ductile iron pipe offers several options for joint restraint systems. These systems aim to prevent movement and separation at the pipe joints, ensuring a secure and leak-free connection. The commonly used joint restraint systems for ductile iron pipe include the following: 1. Mechanical Joint Restraint: This system involves a joint adapter and a restraining gland. The joint adapter is bolted to the pipe, while the restraining gland is bolted to the adjacent pipe or structure, preventing any movement. 2. Push-on Joint Restraint: This system uses a push-on joint along with a restraining gland that is bolted to the pipe or structure. The gland grips the pipe, providing axial restraint and preventing movement. 3. Flex-Ring Joint Restraint: This system employs a flexible rubber ring installed inside the pipe's bell. The ring expands against the pipe, ensuring a tight and secure connection by providing radial restraint. 4. Harness Joint Restraint: This system includes a harness wrapped around the pipe and connected to a restraining gland. The harness offers both axial and radial restraint, keeping the pipe in place. 5. Grip-Lock Joint Restraint: This system involves a wedge-shaped restraint inserted into the pipe's bell. The wedge expands and locks into place, providing both axial and radial restraint. 6. Restrained Joint System: This system combines mechanical and flexible joint restraints. It typically includes a mechanical joint adapter, a flexible joint restraint, and a restraining gland, offering both axial and radial restraint. Engineers typically specify these joint restraint systems based on factors like pipe diameter, operating pressure, and soil conditions. Each system has its own advantages and limitations, and the selection depends on the specific project needs and constraints.
Q: Are ductile iron pipes resistant to external loads?
Generally, external loads pose little challenge to ductile iron pipes. Ductile iron, a variant of cast iron, undergoes treatment with magnesium and cerium additives to enhance its flexibility and durability. As a result, these pipes possess the ability to endure substantial external pressure and stress without succumbing to cracks or fractures. Ductile iron pipes find extensive implementation in scenarios where heavy loads are anticipated, including underground water distribution systems, sewer lines, and industrial pipelines. Their exceptional resistance to external loads has been thoroughly validated, establishing them as a dependable option for diverse infrastructure ventures.
Q: Principles for the antiseptic treatment of ductile iron pipes
Anti corrosion process of ductile iron pipe:1. asphalt paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying.2. cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.3. epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q: Are ductile iron pipes suitable for use in wastewater pumping stations?
Indeed, in wastewater pumping stations, ductile iron pipes exhibit suitability. Ductile iron, a resilient and robust substance, possesses the capacity to endure the demanding circumstances and corrosive properties of wastewater. With its exceptional resistance to corrosion and ability to withstand high-pressure settings, ductile iron pipes represent an optimal selection for the conveyance of wastewater within pumping stations. Notably, these pipes boast an extended lifespan and necessitate minimal maintenance, thereby reducing operational expenses and guaranteeing dependable and effective wastewater transportation.
Q: Are ductile iron pipes recyclable?
Yes, ductile iron pipes are recyclable. Ductile iron is a type of cast iron that has superior strength and durability, making it an excellent choice for various applications, including water and sewage systems. When these pipes reach the end of their lifespan, they can be recycled and reused. The recycling process involves melting down the ductile iron pipes and using the molten metal to produce new pipes or other iron-based products. Recycling ductile iron pipes not only helps to conserve natural resources but also reduces the amount of waste that goes into landfills. Therefore, ductile iron pipes are considered a sustainable and environmentally friendly option for piping systems.
Q: Are ductile iron pipes resistant to chemicals?
Generally, ductile iron pipes exhibit resistance to chemicals. Ductile iron, a variety of cast iron, is fortified with small amounts of magnesium to enhance its strength and ductility. This alloying process effectively heightens its ability to withstand corrosion and chemical attack. Ductile iron pipes have found extensive use in multiple applications, such as water supply, wastewater treatment, and industrial piping systems, where they may encounter a range of chemicals. Nevertheless, it is crucial to acknowledge that the resistance of ductile iron pipes to chemicals can vary based on the specific type and concentration of the chemical in question. Thus, it is advisable to seek guidance from the manufacturer or a qualified engineer to ascertain the suitability of ductile iron pipes for a particular chemical application.
Q: Are ductile iron pipes suitable for underground applications?
Yes, ductile iron pipes are suitable for underground applications. They are known for their durability, strength, and resistance to corrosion, making them ideal for use in underground environments where they may be exposed to moisture and soil conditions. Additionally, ductile iron pipes have a long lifespan and can withstand heavy loads, making them a reliable choice for underground applications such as water and sewage systems.
Q: Can ductile iron pipes be used for river crossings?
Ductile iron pipes are suitable for river crossings. With their strength and durability, they can endure the pressure and stress of being buried and crossed by a river. Ductile iron is widely used in water and sewage systems, proving its reliability for river crossings. Nevertheless, it is crucial to account for additional factors like river depth, pipe size and weight, and the installation procedure. This guarantees the appropriate design and installation of ductile iron pipes for river crossings.
Q: Can ductile iron pipe be used for municipal water supply?
Indeed, municipal water supply systems have extensively relied on ductile iron pipe for numerous years, owing to its exceptional durability, strength, and corrosion resistance. Its suitability for underground use is evident in its ability to endure high pressure and substantial loads. Moreover, ductile iron pipe boasts an extended lifespan, often surpassing 100 years, making it a fiscally prudent option for municipal water supply systems. In summary, ductile iron pipe serves as a dependable and prevalent material for guaranteeing the secure and effective transportation of water to communities.
