Frequently Asked Questions (FAQ)
❓What makes ceramic lined pipe more wear-resistant than steel pipes?
Ceramic lined pipes use high-performance structural ceramics that offer wear resistance 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. This dramatically extends service life in abrasive environments such as powder processing, slurry transport, and mining applications.
❓What temperature range can ceramic lined pipes withstand?
Thanks to a stable crystalline structure, ceramic lined pipes operate normally across a wide temperature range of -50°C to 500°C. Their linear expansion coefficient (6–8 × 10⁻⁶ /°C) is approximately half that of standard steel pipes, ensuring excellent thermal stability.
❓Are ceramic lined pipes suitable for corrosive chemical environments?
Yes. High-performance structural ceramics such as Al₂O₃ and SiC demonstrate excellent resistance to a wide range of aggressive media including HCl, H₂SO₄, H₃PO₄, HNO₃, and NaOH solutions at elevated temperatures. Refer to the Anti-Corrosive Performance Reference Table above for detailed ratings.
❓What industries are ceramic lined pipes commonly used in?
Ceramic lined pipes are widely used across power plants, steel plants, mining, chemical plants, coal chemical industry, fertilizer production, coal washing plants, metallurgical industry, new energy (lithium battery materials), and environmental protection systems. They are ideal wherever abrasion, corrosion, or high-temperature resistance is required.
❓How long is the expected service life of a ceramic lined pipe?
Based on over 20 years of field operation data, ceramic lined pipes are engineered to provide a service life of at least 10 years under normal operating conditions. This significantly reduces maintenance frequency and lowers long-term operational costs compared to conventional steel pipes.
❓What is the flow resistance characteristic of ceramic lined pipes compared to seamless steel pipes?
Ceramic lined pipes feature a smooth internal surface with no corrosion or spiral protrusions, resulting in a clean resistance coefficient of 0.0193 — lower than that of seamless steel pipes. This superior smoothness reduces flow resistance, which directly lowers energy consumption and operational costs over the pipeline's lifetime.
