Tubes en céramique d’alumine 99% de grande taille

Large-Size 99% Alumina Ceramic Tubes are high-performance industrial components engineered from 99% pure alumina (Al₂O₃), designed to meet the stringent demands of heavy-duty applications requiring exceptional thermal, mechanical, and chemical stability.

Their excellent thermal shock resistance (capable of enduring rapid temperature changes without cracking) and low thermal conductivity make them indispensable in high-heat environments such as industrial furnaces, heat treatment equipment, and thermal insulation systems. Electrically, they act as reliable insulators with volume resistivity exceeding 10¹⁴ Ω·cm at room temperature, even retaining insulating properties at elevated temperatures, suitable for high-voltage electrical applications.

Chemically inert to most acids, alkalis, and organic solvents (excluding strong hydrofluoric acid), these tubes excel in chemical processing, waste treatment, and corrosive fluid handling. Their smooth, dense surface (achievable with precision grinding to Ra ≤ 0.8μm) ensures minimal friction and easy cleaning, while customizable features like flanges, holes, or stepped sections can be added via specialized diamond machining for seamless integration into complex systems.
