Advanced Alumina Ceramic Tube with 99.7% Purity and Wear Resistance

Advanced Alumina Ceramic Tube with 99.7% Purity and Wear Resistance. These 1800C high-grade tubes are widely used in thermocouple protection and industrial furnaces. We offer custom designs including both ends open, one end closed, and multi-hole configurations (1, 2, 4, or 6 holes). Sizes range from 6mm to 180mm for outer diameter, and lengths from 10mm to 3000mm.

The product is manufactured using high-quality ceramic materials through hot, dry-pressed, or injection molding, followed by high-temperature sintering. These tubes feature high hardness, excellent insulation, and superior wear resistance. They are essential for material handling in coal-fired power generation, metallurgy, and mining industries.

• ✔ 1. Extreme high temperature stability up to 1800°C under reducing, inert, and high vacuum conditions.
• ✔ 2. Exceptional wear and abrasion resistance for long-term industrial use.
• ✔ 3. Superior chemical corrosion resistance even at elevated temperatures.
• ✔ 4. High dielectric properties for electrical insulation applications.
• ✔ 5. Excellent gas tightness to provide protective atmospheres or high vacuum environments.

Usage Guidelines:

• ● Alumina products are fragile. Handle with care during unpacking and transportation.
• ● Inspect for micro-cracks before use; damaged products should not be utilized.
• ● Ensure products are completely dry. If wet, dry naturally or slowly in an oven.
• ● Avoid overloading tubes to prevent uneven heating and thermal stress.

Standard packaging includes polyfoam-filled interiors and external wooden cases for maximum protection. Shipping options include:

• ✈ Express Delivery (DHL/FedEx) - Door to door.
• ✈ Air Freight to nearest airport.
• 🚢 Sea Freight to nearest seaport.
