Specification of 99.5 % Corundum Ceramic Insulator / Alumina Tube For Electrical Furnace, Industrial Corundum 99% Alumina Tube Ceramic Tube

This alumina ceramic tube offers top performance for demanding industrial heating. Its composition is 99.5% pure corundum (aluminum oxide). This high purity delivers outstanding properties essential for furnace applications. You get a product built to withstand intense conditions. These tubes handle extreme temperatures up to 1750°C (3182°F). They resist thermal shock very well. Sudden temperature changes won’t easily crack them.

Electrical insulation is another major strength. The material provides excellent dielectric properties. This makes the tube ideal for separating electrical components inside high-temperature furnaces. It prevents dangerous short circuits. You need reliable insulation where heat and electricity meet. This alumina tube delivers that safety.

Mechanical strength is impressive. The tube resists wear and abrasion effectively. It maintains structural integrity under load. Chemical resistance is also high. Most acids and alkalis won’t damage it. This durability ensures a long service life. You avoid frequent replacements.

Common uses include lining electrical furnace elements. It protects heating coils and resistors. The tube works well as a protective sheath for thermocouples and thermocouples. It shields sensors in harsh furnace atmospheres. Industrial processes like sintering, annealing, and heat treating rely on it. The tube provides a stable, inert environment for sensitive work.

Standard dimensions are available. Typical sizes include outer diameters from 10mm to 150mm. Wall thickness usually ranges from 3mm to 15mm. Lengths can be customized. We offer tubes cut to your specific requirements. This flexibility helps integrate the tube into your existing furnace setup. You get a component tailored for your equipment.

Key benefits focus on reliability under stress. The tube ensures consistent furnace operation. It minimizes downtime due to part failure. Performance remains stable over prolonged high-temperature exposure. This translates to cost savings through reduced maintenance. Your process efficiency improves.

Applications of 99.5 % Corundum Ceramic Insulator / Alumina Tube For Electrical Furnace, Industrial Corundum 99% Alumina Tube Ceramic Tube

These corundum ceramic tubes are essential for tough industrial heating. They are made from 99.5% alumina. This high purity gives them special properties. They handle extreme heat very well. Temperatures over 1700°C are no problem. They won’t melt or weaken. This makes them perfect for furnace linings, thermocouple protection tubes, and sample holders.

Electricity flows in furnaces. These tubes stop it. They are excellent electrical insulators. Current cannot pass through them easily. This keeps furnace operations safe and controlled. You need this insulation near heating elements or wiring.

Chemicals can damage many materials. Not these tubes. They resist acids and bases very well. Harsh furnace atmospheres won’t eat them away. So they last longer in tough conditions. You get reliable performance over time.

Factories use them in kilns, sintering furnaces, and heat treatment setups. Labs rely on them too. Their strength and stability are key. They don’t crack easily under rapid temperature changes. This thermal shock resistance is vital. Parts must survive heating and cooling cycles.

Durability matters. These tubes are hard and wear-resistant. They withstand physical abrasion inside the furnace. You won’t need replacements as often. This saves money and downtime. Their dimensional stability is another plus. They keep their shape and size under heat. This ensures consistent results in your processes.

5 FAQs of 99.5 % Corundum Ceramic Insulator / Alumina Tube For Electrical Furnace, Industrial Corundum 99% Alumina Tube Ceramic Tube

People often ask about alumina ceramic tubes. What’s the maximum temperature they handle? These tubes withstand continuous use at 1700°C. Short bursts might reach 1800°C. Don’t exceed this limit. The tube will crack or fail.

Why choose 99% or 99.5% purity? Higher purity means better performance. It offers superior resistance to heat and chemicals. It prevents contamination in sensitive processes. This purity is essential for demanding furnace applications. Lower grades won’t last as long under stress.

What sizes are available? These tubes come in many diameters and lengths. Standard sizes exist. Custom sizes are possible too. Always confirm the exact dimensions needed for your furnace. Measure carefully before ordering.

How durable are these tubes? They are extremely hard and wear-resistant. They last a long time under high heat. Remember they are brittle ceramics. Avoid impacts or sudden temperature changes. Handle them with care during installation and use.

Is installation difficult? Installing them is usually straightforward. Ensure the tube fits the furnace design correctly. Support the tube properly along its length. Prevent any stress points. Allow for thermal expansion during heating cycles. Follow the furnace manufacturer’s guidelines closely.
