❓ Frequently Asked Questions
Q What makes ceramic lined pipes more wear-resistant than steel pipes?
Ceramic lined pipes use structural ceramics that offer wear resistance 266 times greater than manganese steel and 171.5 times greater than high-chromium cast iron. This exceptional hardness (up to HRA 94 for SiC) makes them ideal for powder and slurry conveying systems where abrasion is a major concern.
Q What is the operating temperature range of ceramic lined pipes?
Ceramic lined pipes can operate normally across a wide temperature range of -50°C to 500°C. Their stable crystalline structure and low linear expansion coefficient (6–8 × 10⁻⁶ /°C — approximately half that of steel pipes) ensure excellent thermal stability throughout this range.
Q Which ceramic material is best for highly corrosive acid environments?
For most acid environments such as HCL, H₂SO₄, H₃PO₄, and HNO₃, both ZrO₂ and 99.9% Al₂O₃ achieve an "A" rating (≤ 0.1 mmg/cm²/day), meaning negligible corrosion. SiC also performs excellently across nearly all listed media, including HF. Material selection should be based on the specific chemical, concentration, and operating temperature.
Q 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 under normal operating conditions. This significantly reduces maintenance frequency, downtime, and long-term operational costs compared to conventional steel pipelines.
Q 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, fly ash), mining (mineral slurry, tailings), chemical plants (acid/alkali slurries), coal chemical industry, fertilizer production, metallurgy, and new energy sectors (lithium carbonate, lithium iron phosphate transport).
Q How does the flow resistance of ceramic lined pipes compare to seamless steel pipes?
Ceramic lined pipes feature a smooth internal surface with a clean resistance coefficient of 0.0193, which is lower than that of seamless steel pipes. Unlike steel pipes, they do not develop internal corrosion or spiral protrusions over time, ensuring consistently low flow resistance and reduced pump energy consumption throughout their service life.
