Ductile Iron Pipe Production Process
Smelting: Melt iron ore or scrap iron, add appropriate carbon content and other alloying elements to obtain suitable molten iron.
Spheroidizing: Add magnesium or rare earth elements to molten iron so that graphite in the molten iron is precipitated in the form of balls, thereby obtaining ductile iron.
Centrifugal casting: Inject ductile iron liquid into a rotating mold, and evenly distribute the molten iron on the inner wall of the mold through centrifugal force, and form a pipe body after cooling.
Heat treatment: Heat treatment is performed on the cast pipe body to improve its mechanical properties and toughness.
Coating treatment: According to the use requirements of the pipeline, the inner and outer surfaces of the pipeline are coated to enhance its corrosion resistance.
Advantages of Ductile Iron Pipes Better Mechanical Properties
- DN80-DN300: Usually by bundles.
- DN350-DN2000: Usually by bulk.
- During transportation, the pipes are fixed by timbers, blocks, nails & steel ropes with cushions at the side in possible moving directions.
- Bulk or containers for shipment, and trucks or train for inland transport.
