DN 300 Ductile Iron Pipe Type

Product Description 

Ductile Iron Pipe uses and properties

1. Ductile cast iron pipes are mainly used for water supply and gas transmission. They are a relatively good material for tap water supply.
2. Advantages of ductile iron: 1. Reduce stress concentration; 2. High strength; 3. High elongation; 4. Impact resistance; 5. Corrosion resistance; 6. Good sealing.
3. Ductile cast iron pipes are mainly composed of pig iron, carbon, silicon, manganese, sulfur, phosphorus, magnesium and other materials. The inner wall is lined with cement and the outer wall is anti-corrosion treated. A water-cooled metal mold centrifuge is used for casting. High-temperature molten iron is continuously poured into a high-speed rotating pipe mold, and the molten iron is solidified through water cooling to form a ductile iron pipe.
4. The construction process of ductile iron pipe water supply: measuring and laying out - excavation of the pipe trench - sand pad - lowering the pipe - cleaning the inside of the pipe and the pipe mouth - putting on the rubber ring - installing the pipe - returning the pipe to the earth - building the well chamber with water , Pressure test - pipeline valves - pipe fittings installation - backfill - pipeline cleaning - disinfection and completion acceptance.

4. Water supply ductile iron pipe
The classification of ductile iron pipes includes water supply ductile iron pipes.
Scope of application: water supply pipeline
Characteristics of ductile iron pipe
1. Beautiful appearance and smooth inner wall
Reduce the frictional resistance of fluid, small friction coefficient, anti-wear, non-scaling, improve fluid transportation efficiency and reduce noise, and resist corrosion of the inner wall of the pipeline
2.Has high impact strength
Reduces breakage problems during construction and use. Particularly suitable for airport, road and railway drainage pipes.
3.Wide operating temperature range
It has good weather resistance and good dimensional stability when temperature changes.
