As a leader in the industry, DINSEN constantly updates production technology, actively caters to consumers’ purchasing needs, strives to improve service levels, and provides customers with better products and services.
1. Production of double flange welded ductile iron pipes
Raw material selection
Ductile iron pipes use high-quality pig iron as the main raw material, and through strict screening and proportioning, the quality of raw materials is ensured to be stable.
Adding an appropriate amount of spheroidizer and inoculant allows the molten iron to form a spheroidal graphite structure during the solidification process, thereby greatly improving the strength and toughness of the pipe.
Casting process
Advanced centrifugal casting technology is used to evenly distribute the molten iron in the high-speed rotating mold to form a dense pipe wall structure.
Strictly control parameters such as casting temperature, cooling rate and casting time to ensure the dimensional accuracy and quality stability of the pipe.
Processing and treatment
The cast pipes are finely processed, including cutting, beveling, flange welding and other processes.
High-precision processing equipment and advanced welding technology are used to ensure that the connection between the flange and the pipe is firm and reliable, and the sealing performance is excellent.
2. Uses of double-flange welded ductile iron pipes
Urban water supply and drainage projects
Ductile iron pipes have good corrosion resistance and sealing properties, can effectively prevent leakage and pollution of water resources, and are widely used in urban water supply, drainage and sewage treatment systems.
Its high strength and toughness can withstand large water pressure and external loads, ensuring the safe and stable operation of the water supply and drainage system.
Industrial field
In the industrial field, ductile iron pipes can be used to transport various corrosive media, high-temperature and high-pressure fluids, etc.
For example, in the chemical, petroleum, electric power and other industries, ductile iron pipes are used as conveying pipelines with reliable performance and long service life.
Agricultural irrigation
The corrosion resistance and wear resistance of ductile iron pipes make them suitable for agricultural irrigation systems, which can provide water for farmland in a long-term and stable manner.
Its convenient connection and fast construction characteristics have also greatly improved the construction efficiency of agricultural irrigation projects.
3. Advantages of double flange welded ductile iron pipes
High strength
The tensile strength and yield strength of ductile iron pipes are much higher than those of ordinary cast iron pipes and steel pipes, and can withstand large external loads and internal pressures.
In engineering applications, it can reduce the wall thickness and weight of pipes and reduce engineering costs.
Good toughness
Ductile iron pipes have good toughness and ductility, and can maintain good integrity when subjected to external force impact or natural disasters such as earthquakes, reducing the risk of pipeline damage.
Strong corrosion resistance
The corrosion resistance of ductile iron pipes is better than that of ordinary steel pipes and cast iron pipes, and can operate stably for a long time in various harsh environments.
The inner wall adopts anti-corrosion measures such as cement mortar lining or epoxy coating, which further improves the corrosion resistance of the pipe.
Good sealing performance
The double flange welding connection method ensures the sealing performance of the pipeline and can effectively prevent leakage and pollution of water resources.
Sealing materials such as rubber sealing rings are used at the flange connection to ensure the tightness and reliability of the connection.
Convenient and quick construction
The weight of ductile iron pipes is light, which is convenient for transportation and installation.
The double flange connection method makes the connection of pipelines more convenient and quick, greatly shortening the construction period.
