PRODUCTION FLOW OF DUCTILE IRON PIPES
Observe the meticulous sequence of crafting our ductile iron pipes, designed for superior performance and resilience: Begin with the melting of iron, then proceed to the purification of this molten metal. Our intricate heating and spheroidization process follows, ensuring the optimal molecular structure. This is followed by expert centrifugal casting, essential annealing, and a protective zinc spray. Each pipe undergoes meticulous finishing and polishing, rigorous hydrostatic testing, and robust cement lining. We meticulously cure the cement, apply a durable bitumen coating, and finally prepare the product for secure packing.
Ductile Iron Pipe stands as a paragon of versatility, adapting seamlessly across multiple environments owing to its exceptional strength, remarkable resistance to corrosion, and unparalleled flexibility:
1. Municipal water supply and drainage system
1.1 Tap water transportation
Advantages: The internal lining of cement mortar or high-quality epoxy resin guarantees the purity and safety of water, conforming to the rigorous GB/T 17219 standard.
Scenario: Perfectly suited for urban main water supply networks and as the critical outlet pipe from water plants.
1.2 Sewage discharge
Advantages: An external layer of asphalt or epoxy coal tar ensures robustness against acid and alkali, effectively managing a pH range between 4 and 10.
Scenario: Essential for the inlet and outlet conduits of sewage treatment facilities and for systems combining rainwater and sewage.
2. Industrial field
2.1 Mine drainage
Our pipes boast an impressive pressure resistance, rated between PN10-PN25, making them ideal for high-pressure environments such as deep wells.
Case Study: Deployed in the South African gold mine drainage system, these pipes (DN800, withstanding up to 2.5MPa) exemplify durability and strength.
2.2 Chemical medium transportation
Special treatment: Employing a robust polyurethane lining or ceramic coating, our pipes are fortified against the corrosive forces of H2S and chloride, ensuring endurance and reliability.
Limitation: For conditions involving strong acids (pH<2) or elevated temperatures (>80ºC), stainless steel becomes a necessity.
3. Agricultural irrigation
An innovative and efficient water-saving irrigation pipe network.
Advantages: Boasting a lifespan that exceeds half a century with zero maintenance, these pipes outperform PVC, which is susceptible to aging.
