Ductile Iron Pipe is widely used in various environments due to its high strength, corrosion resistance and flexibility:

1. Municipal water supply and drainage system

1.1 Tap water transportation
Advantages: Lined with cement mortar/epoxy resin to ensure water quality (in compliance with GB/T 17219 standard).
Scenario: Urban main water supply network, water plant outlet pipe.

1.2 Sewage discharge
Advantages: Externally coated with asphalt/epoxy coal tar, resistant to acid and alkali corrosion (pH 4-10).
Scenario: Inlet and outlet pipes of sewage treatment plants, rainwater and sewage combined pipes.

2. Industrial field

2.1 Mine drainage
Pressure resistance level: PN10-PN25, suitable for deep well high pressure environment.
Case: South African gold mine drainage system (DN800, pressure bearing 2.5MPa).

2.2 Chemical medium transportation
Special treatment: polyurethane lining/ceramic coating, resistant to H2S and chloride corrosion.
Limitation: Strong acid (pH<2) or high temperature (>80ºC) requires stainless steel.

3. Agricultural irrigation
Water-saving irrigation pipe network
Advantages: lifespan of more than 50 years, maintenance-free (compared to PVC which is prone to aging).
