Ductile Iron Pipe
Ductile iron pipe is a pipe with excellent performance. Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of molten iron above No. 18 after adding spheroidizing agent through centrifugal ductile iron casting machine. This kind of pipe is referred to as spheroidal pipe, ductile iron pipe and ductile cast pipe, etc. The graphite inside it exists in spherical form. Generally, the size of graphite is 6-7, and the spheroidization level of the cast pipe is required to be controlled to 1-3, and the spheroidization rate is ≥80%, which greatly improves the mechanical properties of the material.

High Strength And Toughness
The ductile iron pipe is treated by a special spheroidizing process, so that the internal graphite exists in a spherical form, which greatly improves the mechanical properties of the material. This kind of pipe not only has high tensile strength and yield strength, but also has good toughness, can withstand large impact and pressure, and ensure the safety and stability of the pipeline system.
Excellent Anti-corrosion Performance
During the manufacturing process of ductile iron pipes, a variety of anti-corrosion measures are often adopted on the inner and outer walls, such as lining cement mortar, outer wall zinc spraying and asphalt coating. These anti-corrosion treatment layers effectively isolate the contact between the pipe and the corrosive medium, greatly prolong the service life of the pipeline and reduce maintenance costs.
Good Sealing
The ductile iron pipe adopts a flexible interface design, such as rubber sealing rings, to ensure the tightness and sealing of the pipeline connection. This design can not only effectively prevent medium leakage, but also adapt to complex working conditions such as foundation settlement, ensuring the normal operation of the pipeline system.
Easy Installation, Low Maintenance Cost, Long Life, Good Economy
Compared with other pipes, ductile iron pipes are lighter, easier to transport, and no special equipment is required during installation, which greatly reduces the difficulty and cost of construction. At the same time, due to its corrosion resistance and wear resistance, it has a long service life, generally more than 50 years. The maintenance cost is low and the long-term use is economical.
Ductile Iron Pipe Applications
Urban Water Supply System
Ductile iron pipe is an ideal choice for urban water supply system. Its excellent anti-corrosion performance and long life ensure the safety and stable supply of water quality. At the same time, the easy installation and low maintenance cost of ductile iron pipe also make it the preferred material for the transformation and expansion of urban water supply network.
Drainage System
In the field of drainage, ductile iron pipe is widely used in sewage discharge and rainwater collection system due to its good corrosion resistance and pressure bearing capacity. It can withstand large water pressure and corrosive media to ensure the smooth operation of drainage system.
