Frequently Asked Questions (FAQ)
What makes ceramic lined pipes more wear-resistant than steel pipes?
Structural ceramics used in ceramic lined pipes offer wear resistance that is 266 times greater than manganese steel and 171.5 times greater than high-chromium cast iron. This exceptional hardness (up to HRA 94) significantly reduces material loss in abrasive environments such as powder processing and slurry transport systems.
What is the operating temperature range of ceramic lined pipes?
Ceramic lined pipes can operate normally across a wide temperature range from -50°C to 500°C. Their stable crystalline structure and low linear expansion coefficient (6–8 × 10⁻⁶/°C, roughly half that of steel) ensure excellent thermal stability throughout this range.
Which ceramic materials offer the best corrosion resistance?
ZrO₂, 99.9% Al₂O₃, and SiC all demonstrate excellent corrosion resistance (rated "A") against most common acids and alkalis including HCL, H₂SO₄, H₃PO₄, HNO₃, and NaOH. SiC in particular shows strong resistance even to HF, making it suitable for highly aggressive chemical environments.
How long is the expected service life of ceramic lined pipes?
Based on over 20 years of field operation data, ceramic lined pipes are engineered to provide a minimum service life of 10 years. Their superior wear and corrosion resistance greatly reduces the frequency of maintenance shutdowns and replacement costs compared to conventional steel or cast iron pipelines.
In which industries are ceramic lined pipes most commonly used?
Ceramic lined pipes are widely used across power plants (limestone slurry), steel plants (coal powder and fly ash), mining (mineral slurry and tailings), chemical plants (acid/alkali slurries), coal chemical industry (black water and coal slag), new energy (lithium carbonate and lithium iron phosphate), and environmental protection applications.
How does the flow resistance of ceramic lined pipes compare to seamless steel pipes?
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 reduced flow resistance directly lowers pump energy consumption and overall operational costs in fluid and slurry transport systems.
