API 5L X65 Cladding Pipe Carbon Steel Seamless Pipe Cladded with Inconel 625

API 5L X65 carbon steel seamless pipe, internally clad with a metallurgically bonded layer of Inconel 625, combines the high strength and cost-effectiveness of the steel substrate with the exceptional corrosion, erosion, and temperature resistance of the nickel alloy liner. This bifunctional design provides durable, economical performance in demanding environments (e.g., sour service, subsea flowlines, acid injection, high-chloride process piping) where solid alloy construction is cost-prohibitive and bare carbon steel would fail.

API 5L X65 Carbon Steel Seamless Pipe Cladded with Inconel 625

Base Material

API 5L X65 Carbon Steel --
API 5L X65 is a steel grade used in pipelines for transporting oil and gas. It signifies a minimum yield strength of 65,000 psi (450 MPa) and is part of the broader API 5L standard for line pipe. The 'X' in X65 indicates the grade, while the '65' refers to the minimum yield strength in thousands of psi.

Cladding Material

Inconel 625 --
Inconel 625 is a nickel-chromium-molybdenum alloy known for its high strength, excellent corrosion resistance, and good weldability. It's widely used in aerospace, marine, and chemical processing industries due to its ability to withstand high temperatures, corrosive environments, and stress.

Key Purpose of Cladding:

  • Corrosion Protection: Shields the underlying X65 steel from aggressive environments that would rapidly corrode it, such as:

    • Acids (e.g., in acid injection lines)

    • "Sour Service" (H₂S - Hydrogen Sulfide)

    • Seawater or chloride-rich fluids (offshore/subsea)

    • High-temperature oxidation/corrosion

    • Stress Corrosion Cracking (SCC) environments

  • Economic Efficiency: Provides the necessary corrosion resistance where needed (the internal bore) using only a thin layer (typically 2-4mm) of expensive Inconel 625, instead of constructing the entire pipe from solid alloy, which is significantly more costly.

  • Mechanical Integrity: Maintains the high strength, pressure containment capability, and structural support provided by the thick-walled API 5L X65 steel pipe.

  • Resistance to Specific Degradation: Offers excellent resistance to pitting, crevice corrosion, and erosion-corrosion in challenging flow conditions.

  • High-Temperature Performance: Enhances performance in elevated temperature service beyond what carbon steel can withstand.

When to Use Cladding vs. Solid Alloy? Advantages?

1>. Cladding: High-pressure vessels, heat exchangers, large structures needing corrosion resistance.
2>. Solid Alloy: Small components, extreme temperatures/purity (e.g., semiconductor furnaces).

For specific project needs (e.g., temperature, acid concentration), consult corrosion charts to select the optimal cladding alloy!

Factor Clad Pipe Solid Inconel 625
Cost 3–5x lower Very high
Weight Optimized (steel core) Heavy
Strength API X65 structural integrity Lower yield strength (414 MPa)
Corrosion Res. Inconel 625 barrier layer Full resistance

Applications

  • Oil & Gas:

    • Subsea pipelines, risers, flowlines in sour service (H₂S/CO₂ environments).

    • Downhole tubing, manifolds, valves.

  • Chemical Processing:

    • Reactors, heat exchangers, acid handling systems.

  • Power Generation:

    • FGD (Flue Gas Desulfurization) systems, boiler tubes.

  • Onshore & Offshore / Marine:

    • Seawater injection pipes, ballast systems.
