Bimetallic Steel Tube: X52/N08825
Product Description
This explosion-bonded bimetallic tube combines X52 carbon steel (inner layer) with N08825 nickel-chromium alloy (outer layer), delivering superior corrosion resistance and structural integrity for harsh industrial environments. The dual-layer construction achieves optimal performance-to-cost ratio compared to solid alloy solutions.

Key Specifications

• Material Standards:
  X52 complies with API 5L pipeline specifications, while N08825 meets ASTM B423/ASME SB423 for nickel alloys.

• Performance Advantages:

  • Withstands pitting/crevice corrosion in acidic/chloride media (N08825 layer)

  • Maintains mechanical strength up to 540°C (X52 layer)

  • Explosive welding ensures >300 MPa shear strength at interface.

Typical Applications

• Offshore oil/gas riser systems

• Flue gas desulfurization equipment

• Chemical processing reactors with mixed media

Certifications
Available with EN 10204 3.2 certification and customized NDE reports (UT/RT). Standard sizes range from OD 114mm to 406mm with wall thickness 8-25mm.
