Wear Resistant Pipe
TECERA ceramic tile lined pipe is a high-performance composite pipeline built for severe abrasive and corrosive conveying environments. It features a steel outer shell bonded with high-purity alumina or ZTA ceramic tiles on the inner wall, replacing ordinary steel pipes that fail within months under high-velocity abrasive slurry and powder flow.
With a service life 4–10 times longer than bare steel, this solution directly eliminates core pain points including premature wall wear, pipeline leakage, frequent unplanned shutdowns and high replacement costs. It is widely applied in mining slurry transport, coal-fired power ash handling, cement conveying and chemical processing systems.
Core Features & Benefits
Ultra-long wear resistance: Ceramic tiles are formed via isostatic pressing and high-temperature sintering, achieving HRA 85–90 hardness with below 0.1% porosity. The wear life is 4–10 times that of hardened steel, drastically reducing replacement frequency and labor costs, and avoiding environmental penalties caused by material leakage.
Combined abrasion & corrosion protection: Chemically inert alumina ceramic and high-temperature inorganic adhesive maintain stable performance across pH 3–11, resisting pitting and corrosion from acidic slurries, alkaline reagents and chloride media. A single pipeline solution covers mixed working conditions, reducing spare part categories by over 50% and simplifying inventory management.
Reliable high-temperature performance: The inorganic adhesive system supports continuous operation at up to 350°C, with matched thermal expansion coefficients between steel, adhesive and ceramic to absorb thermal stress during temperature cycles. It eliminates the need for expensive high-temperature alloys and reduces maintenance in high-temperature zones by 70%.
Smooth inner bore for energy efficiency: CNC-machined ceramic surfaces with staggered tile layout deliver ultra-low friction, preventing material buildup and blockages in pneumatic conveying. It reduces pipeline pressure loss by 15–25% compared to steel pipes, cutting conveying energy consumption by 10–20%.
Lightweight design for easy installation: With a density only 50–60% of steel wear pipes, the product requires no additional structural reinforcement to existing supports, reducing installation time by 30–50% and lowering total engineering costs.
Staggered tile layout & high-temperature bonding: The staggered joint structure avoids continuous wear grooves along flow direction, extending service life by 50–100% in high-speed conveying. The inorganic adhesive forms ceramic-like bonds, preventing tile detachment even under frequent thermal cycling.
