Q:What are the advantages of using ductile iron pipes over other materials?: There are several advantages of using ductile iron pipes over other materials. Firstly, ductile iron pipes have a high tensile strength, which makes them more resistant to pressure and external forces, reducing the risk of cracks or leaks. Secondly, ductile iron pipes have a longer lifespan compared to other materials, as they are highly durable and resistant to corrosion. Additionally, ductile iron pipes have a smooth internal surface, promoting efficient water flow and minimizing the risk of blockages. Lastly, ductile iron pipes are relatively cost-effective and easy to install, making them a preferred choice for various applications in water distribution, sewer systems, and industrial settings.

Q:Can ductile iron pipes be used for trench crossings?: Yes, ductile iron pipes can be used for trench crossings. Ductile iron pipes are known for their high strength and durability, making them suitable for various applications including trench crossings. They have the ability to withstand heavy loads and provide increased resistance to external forces, making them a reliable choice for such purposes.

Q:What is the expected pressure rating for ductile iron pipes?: The expected pressure rating for ductile iron pipes can vary depending on various factors such as the pipe diameter, wall thickness, and the specific application it is being used for. However, generally speaking, ductile iron pipes are designed and manufactured to withstand high-pressure conditions. They are commonly used in water and wastewater systems, where they can typically handle pressures ranging from 150 psi (pounds per square inch) up to 350 psi or even higher. It is important to consult the manufacturer's specifications or relevant industry standards for specific pressure ratings based on the pipe's size and application to ensure safe and reliable operation.

Q:Are ductile iron pipes suitable for use in seismic areas?: Yes, ductile iron pipes are suitable for use in seismic areas. Ductile iron has high strength and flexibility, making it resistant to seismic forces. It is able to withstand ground movements and vibrations during earthquakes without significant damage, making it a reliable choice for water and wastewater infrastructure in seismic areas.

Q:Ductile iron pipe is how many years warranty: 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:What is the typical lifespan of ductile iron pipe?: The lifespan of ductile iron pipe can differ based on several factors, including the pipe's quality, the conditions it faces, and the maintenance practices employed. On average, ductile iron pipe typically lasts about 100 years. This longevity is a result of its inherent strength and durability, allowing it to withstand high pressure and various environmental conditions. Furthermore, ductile iron pipe is often coated with protective materials like cement mortar lining or polyethylene encasement, which further enhance its durability. Regular inspections and maintenance can also contribute to extending the lifespan of ductile iron pipe by promptly identifying and addressing any issues or potential damages.

Q:Is the spigot and socket connection of the ductile iron tube reversed?: The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.

Q:What is the expected joint deflection of ductile iron pipes?: The expected joint deflection of ductile iron pipes depends on various factors such as the diameter, wall thickness, and type of joint used. However, in general, ductile iron pipes are designed to have a joint deflection capability of up to 5 degrees for restrained joints and up to 10 degrees for flexible joints.

Q:How do ductile iron pipes handle ground movement in earthquake-prone areas?: Ductile iron pipes are designed to withstand ground movement in earthquake-prone areas due to their inherent strength and flexibility. The ductile nature of the iron allows the pipes to deform and absorb the seismic energy without breaking or fracturing. This ensures their durability and ability to maintain water supply and drainage systems even during seismic events. Additionally, ductile iron pipes have superior joint integrity, which further enhances their resistance to ground movement and minimizes the risk of leaks or pipe failure.

Q:How can the ductile iron pipe be tested?: In the hydraulic test, the ductile iron pipe can not be close to the back, support, pipe end and so on. The inspection must be carried out after all stops
