Seamless Incoloy 925 Nickel Alloy Steel Pipe

Seamless Incoloy 925 Nickel Allloy Steel Pipe is a high-strength, corrosion-resistant nickel-iron-chromium alloy, enhanced with molybdenum, copper, titanium, and aluminum. Referred to as a "nickel alloy steel" in industrial contexts due to its significant iron content, this precipitation-hardenable superalloy is engineered for exceptional strength and resistance to aggressive environments, particularly in sour gas (H₂S, CO₂) and chloride-rich conditions. Seamless construction ensures structural integrity under high pressure and temperature, making it ideal for critical applications in oil and gas, marine, and chemical processing industries.

Applications

    • Oil and Gas: Downhole tubing, casing, and completion equipment in sour gas wells (NACE MR0175/ISO 15156 compliant).
    • Marine: Piping, valves, and fittings exposed to seawater.
    • Chemical Processing: Piping systems for corrosive fluids, heat exchangers.
    • Aerospace: High-strength, corrosion-resistant components.

Additional Notes

  • Heat Treatment: Solution annealing at 980–1010°C, followed by age-hardening at 732–760°C, maximizes strength and corrosion resistance.
  • Standards Compliance: Meets NACE MR0175/ISO 15156 for sour service in oil and gas.
  • Fabrication: Can be welded with matching Incoloy 925 filler metals; post-weld heat treatment may be required to restore properties.
