Ceramic-Lined Low Carbon Steel Pipe

Abrasion & Corrosion Resistant

Low carbon steel pipes (q235 grade) with centrifugal shs-bonded alumina ceramic lining deliver 90% lower wear vs. bare steel. ideal for abrasive/corrosive applications in mining, power plants, and chemical industries. withstand 20 m/s particle flow, ph 1-14 chemicals, and -30°c to 300°c temperatures. custom sizes 25mm-120" od.

Optimized for industries prioritizing cost efficiency without sacrificing durability, these pipes combine Q235 steel’s weldability/formability with ceramic’s extreme wear resistance. Proven in coal mines and power plants globally, they cut slurry system maintenance costs by 50% while extending service life to 10+ years in severe abrasion environments.

Structure & Manufacturing

Base Material

  • Material Q235 low carbon steel (ASTM A53 Grade B equivalent)
  • Yield strength ≥235 MPa
  • Cost advantage Cost-effective alternative to stainless steel

Ceramic Lining

  • Composition 92-95% alumina oxide (α-Al₂O₃)
  • Thickness 4-6mm (centrifugal SHS process)
  • Mohs hardness ≥9.0 (3x harder than tool steel)

Bonding

  • Method Micro-roughened steel surface
  • Shear strength >12 MPa

Key Advantages

Ultra-High Wear Resistance

  • 10-15x longer service life than uncoated pipes in coal slurry transport

  • Handles silica sand, iron ore tailings, and fly ash at 15-25 m/s flow rates

Chemical Protection

  • Ceramic barrier isolates steel from acids/alkalis (e.g., H₂SO₄, NaOH)

  • Optional epoxy sealing for pH <2 environments

Thermal Stability

  • Continuous use: -30°C to 300°C (short peaks to 500°C)

  • Avoid thermal shock >200°C/min

Economic Efficiency

  • 40% lower cost than stainless-ceramic composite pipes

  • Reduced maintenance downtime and replacement frequency
