The function of ceramic tile steel pipe
Ceramic-lined steel pipe significantly enhances the overall performance of the pipeline under extreme working conditions by coating the inner wall of the steel pipe with a high-hardness ceramic layer (such as alumina or silicon carbide). Its core value lies in addressing the short lifespan of pipelines caused by severe wear, high corrosion, and high-temperature environments in industrial transportation systems. The hardness of the ceramic layer can reach HRA85-90, with a wear resistance ten times that of manganese steel. It can resist acid and alkali corrosion and withstand temperatures of 800-1500°C, extending the pipeline's lifespan by 3-5 times. Meanwhile, its smooth inner wall (with a roughness only 1/6 that of the steel pipe) reduces fluid resistance, effectively preventing the accumulation of scale in viscous media, and ensuring transportation efficiency. In applications across various fields such as mining, power, and chemical industries (such as ore powder transportation, high-temperature flue ducts, and corrosive fluid pipelines), this composite structure fully leverages the synergy between the steel base's pressure-bearing capacity and the ceramic's wear resistance, significantly reducing the frequency of shutdowns for maintenance. A typical example is the extension of the lifespan of iron ore transportation pipes from 3 months to over 2 years, achieving a unified balance of wear resistance, corrosion resistance, heat resistance, and economic efficiency.

Ultra-High Wear Resistance
- Our ceramic-lined steel pipes employ a lining material of 99% pure alumina (Al₂O₃) or silicon carbide (SiC), whose densified crystalline structure delivers a hardness rating of HRA 85-90 (equivalent to Vickers hardness HV 1100-1500).
- Comparative data: 10× harder than manganese steel (HV 200), 40% harder than tungsten-cobalt alloy (HV 800).
- The ceramic layer consumes abrasive particle kinetic energy through micro-plastic deformation + microcrack deflection, with wear rate ≤0.02 cm³/1km·g (per ASTM G65 standard).
Corrosion Resistance
- Al₂O₃/SiC solubility: <0.01 g/m²·h within pH 1-14 (GB/T 1970 test).
- Yttrium oxide (Y₂O₃) doped at grain boundaries blocks acid penetration paths.
- Extreme environment performance:
○98% concentrated sulfuric acid (80°C): Annual corrosion rate <0.1 mm (vs. >5 mm for 316L stainless steel).
○Salt spray (ASTM B117): Zero pitting after 5,000 hours.
- Extreme environment performance:
Extreme Temperature Tolerance
- Thermal expansion coefficient: 7.2×10⁻⁶/°C (gradient-matched to steel substrate's 11.7×10⁻⁶/°C), preventing thermal shock cracking.
- High-temperature strength retention: Bending strength ≥180 MPa at 1200°C (3× higher than refractory bricks).
- Operational limits:
○Oxidizing atmosphere: Al₂O₃ lining sustains operation at 1,500°C (e.g., cement rotary kiln exhaust).
○Reducing atmosphere: SiC lining withstands 1,400°C (e.g., metallurgical coke oven gas).
