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 different methods for joining ductile iron pipe?: There are several methods for joining ductile iron pipe, each with its own advantages and limitations. One common method is mechanical joint (MJ) coupling, which involves using a rubber gasket and a set of bolts and nuts to create a watertight seal between pipe sections. This method is relatively quick and easy to install, but it requires a skilled technician to ensure proper alignment and bolt tightening to prevent leakage. Another method is flanged joint, where the pipe ends are equipped with flanges that are bolted together using gaskets to create a tight seal. This method allows for easy disassembly and reassembly of pipe sections, making it suitable for applications that require frequent maintenance or modifications. However, it is more expensive and time-consuming compared to other methods. One widely used method is push-on joint (POJ), which involves using a rubber gasket and a special lubricant to slide the pipe ends together. This method provides a reliable and watertight seal, and it is relatively quick and easy to install. However, it requires proper alignment and care to avoid damaging the gasket during assembly. Another option is restrained joint (RJ), which uses a mechanical joint coupling with additional features to resist axial forces or thrusts. This method is commonly used in applications where the pipe is subject to internal pressure, external loads, or seismic activity. It provides a secure and rigid connection but may require specialized tools and training for installation. Finally, welding is another method for joining ductile iron pipe. It involves heating the pipe ends and melting a filler metal to create a permanent bond. This method provides a strong and durable connection, but it requires skilled welders and additional time for preparation, welding, and cooling. Welding is often used for specific applications, such as joining sections of pipe with different diameters or connecting to other materials. In summary, the different methods for joining ductile iron pipe include mechanical joint coupling, flanged joint, push-on joint, restrained joint, and welding. The choice of method depends on factors such as the application requirements, installation time, maintenance needs, and budget.

Q: Can ductile iron pipe be used for both water and wastewater applications?: Yes, ductile iron pipe can be used for both water and wastewater applications.
