Ductile iron is widely used in the oil and gas industry due to its high strength, toughness and corrosion resistance.

Application scenarios of ductile iron valves
Low-pressure oil and gas transportation and distribution — Ductile iron valves (such as EN-GJS-400/500) can be used in low-pressure natural gas distribution systems (≤PN16/Class 150): low-pressure pipelines after pressure regulating stations, residential and commercial gas inlet pipelines, auxiliary pipelines of gas storage and distribution stations.
Oilfield water injection system — For low-pressure (≤PN25) water injection pipelines, ductile iron has better corrosion resistance than ordinary cast iron, but water quality (such as additional protection when containing chloride ions and H₂S) still needs to be considered.
Medium and low pressure processes in non-acidic environments — Compressed air and inert gas systems.
