In oil and gas applications, control lines made from Alloy 825 are employed in downhole operations for hydraulic control, chemical injection, and signal transmission. They are often chosen for environments with high pressures, temperatures, and corrosive elements like hydrogen sulfide (H₂S) and carbon dioxide (CO₂). Alloy 825 provides a balance of strength, flexibility, and resistance to sour gas corrosion, making it an ideal choice for downhole tubing in offshore and onshore oil fields.
Alloy 825 (UNS N08825) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. It is designed to provide excellent resistance to both reducing and oxidizing acids, stress-corrosion cracking, and localized attack such as pitting and crevice corrosion. Due to its superior corrosion resistance and strength, Alloy 825 is widely used in harsh environments, including oil and gas applications.
