Frequently Asked Questions
What makes ceramic lined pipes superior to seamless steel pipes in terms of flow resistance?
Ceramic lined pipes feature a smooth internal surface with no corrosion or spiral protrusions, achieving a clean resistance coefficient of 0.0193 — lower than that of seamless steel pipes. This significantly reduces operating resistance, resulting in lower energy consumption and operational costs over the pipeline's lifetime.
How does the wear resistance of ceramic lined pipes compare to traditional metal pipes?
Structural ceramics used in these pipes offer wear resistance that is 266 times greater than manganese steel and 171.5 times greater than high-chromium cast iron. This makes them ideal for powder processing systems and abrasive slurry transport applications, with a guaranteed service life of at least 10 years.
What temperature range can ceramic lined pipes operate in?
Thanks to their stable crystalline structure, ceramic lined pipes operate normally across a wide temperature range of -50°C to 500°C. Their linear expansion coefficient of 6–8 × 10⁻⁶ /°C is approximately half that of steel pipes, ensuring excellent thermal stability and dimensional integrity under thermal cycling conditions.
Which ceramic material offers the best corrosion resistance for highly acidic environments?
Based on the anti-corrosive performance reference table, ZrO₂, 99.9% Al₂O₃, SiC, Graphite, PTFE, and Fluororubber all achieve Grade A ratings (≤ 0.1 mmg/cm²/day) in most acid environments including HCL, H₂SO₄, H₃PO₄, and HNO₃. SiC demonstrates the broadest resistance across all tested media including HF, making it particularly suitable for aggressive chemical environments.
In which industries are ceramic lined pipes most commonly used?
Ceramic lined pipes are widely used across power plants (limestone slurry transport), steel plants (coal powder and fly ash conveying), mining (mineral slurry and tailings), chemical plants (acid and alkali slurries), coal chemical industry, fertilizer production, coal washing, metallurgical slag removal, new energy (lithium carbonate and lithium iron phosphate), and environmental protection applications such as wastewater zero-discharge systems.
What is the expected service life of ceramic lined pipes and how does it reduce maintenance costs?
Ceramic lined pipes have been proven in over 20 years of field operations, with a guaranteed minimum service life of 10 years. Their exceptional wear and corrosion resistance drastically reduces the frequency of pipe replacements and unplanned maintenance shutdowns, leading to significantly lower total lifecycle costs compared to conventional steel or alloy pipelines.
