Specification of High Temperature Ceramic Tube 95% Al2O3 Ceramic Tubes for Furnace Refractory

These ceramic tubes are made from 95% Alumina Oxide (Al2O3). This makes them very strong. They are designed for high temperature use. They work well in furnaces and kilns. These tubes handle intense heat. They resist temperatures up to 1700°C. This is very high. They stay stable even at these extremes. They are perfect for demanding furnace applications. Their main job is acting as liners or sleeves. They protect furnace parts. They also provide pathways inside hot zones. You can use them as thermocouple protection tubes. They shield sensitive instruments from the heat. They are essential for furnace refractory settings. They come in many sizes. Common outside diameters are 10mm, 15mm, 20mm, 25mm, 30mm. Wall thicknesses are usually 2mm, 3mm, 4mm, 5mm. Lengths vary. You can get them in 100mm, 200mm, 300mm, 500mm, or 1000mm pieces. Custom sizes are possible too. They have low thermal conductivity. This means they don’t transfer heat quickly. They help keep heat inside the furnace. They are electrical insulators. This is important near heating elements. They are chemically inert. Harsh chemicals won’t easily damage them. They have high mechanical strength. They resist breaking under pressure or impact. They are very hard. They resist wear and abrasion. They are dense. This density helps them resist chemical attack. They can handle rapid temperature changes. They won’t crack easily from thermal shock. These tubes are long-lasting. They reduce the need for frequent replacements. They are reliable in tough furnace environments. They are good for sintering processes. They are useful in heat treatment furnaces. They are suitable for laboratory kilns. They work well in industrial ovens. You can also use them in ceramic firing kilns. They are versatile components. They are made from high-purity alumina. This ensures consistent performance. They are a smart choice for high-heat protection.

Applications of High Temperature Ceramic Tube 95% Al2O3 Ceramic Tubes for Furnace Refractory

These ceramic tubes are made from 95% Alumina (Al2O3). This material is excellent for very hot environments. It handles temperatures far beyond what most metals can take. This makes them perfect for furnace parts.

The tubes are very resistant to heat. They also resist wear and chemical attack well. Furnaces often have harsh conditions inside. These tubes can survive there. They stay strong and don’t easily break down.

Because of their strength, these tubes last a long time. They are a reliable choice for industrial heating. You won’t need to replace them often. This saves time and money.

One common use is protecting thermocouples. Thermocouples measure temperature inside furnaces. The tube shields the delicate sensor wires. It keeps them safe from direct heat and furnace gases. Without this protection, the thermocouples would fail quickly.

Another application is handling molten materials. These tubes can carry molten metal or glass. They withstand the intense heat and won’t contaminate the material. Their smooth surface helps materials flow easily.

These tubes are also used for gas injection. Hot gases need to be fed into furnace chambers. The alumina tubes deliver the gas reliably. They don’t degrade under the heat and pressure.

The high purity of the alumina (95%) is important. It gives the tubes their key properties. Lower purity ceramics might not perform as well. They might crack or wear out faster under stress.

These tubes are essential for many furnace designs. They provide a stable and durable solution. Industries rely on them for consistent furnace operation.

5 FAQs of High Temperature Ceramic Tube 95% Al2O3 Ceramic Tubes for Furnace Refractory

What are these ceramic tubes made from?

These tubes are mainly alumina. Specifically, they contain 95% aluminum oxide (Al2O3). This high alumina content is key. It gives the tubes excellent high-temperature performance.

How hot can these tubes get?

These tubes withstand very high temperatures. They can handle constant use up to 1700°C (3092°F). Short-term exposure to even higher temperatures is possible. The exact limit depends on the furnace atmosphere.

Why choose 95% Al2O3 over other ceramics?

95% alumina offers a great balance. It provides superb heat resistance. It also resists thermal shock better than some options. It’s strong and hard. These properties make it reliable for tough furnace conditions.

Where are these tubes typically used?

You find these tubes in many industrial furnaces. They work well as thermocouple protection sheaths. They are good furnace liners or support tubes. They guide materials or protect sensors inside hot zones. Kilns and lab furnaces use them too.

How do I install or handle these tubes?

Handle these tubes carefully. They are hard but can break if dropped or hit hard. Use proper supports inside the furnace. Avoid sudden temperature changes. Thermal shock can cause cracks. Follow the furnace manufacturer’s guidelines.
