5 FAQs of Industrial Alumina High Temperature Al2O3 protection Ceramic Corundum Tube Thermocouple

What exactly is this alumina tube?
This is a tough ceramic sleeve. It shields temperature sensors called thermocouples in very hot industrial places. It’s made almost entirely of aluminum oxide (Al2O3). This material is also known as corundum, a very hard form of alumina. The tube physically protects the delicate thermocouple wires inside harsh furnace environments.

Why use alumina for this job?
Alumina handles extreme heat incredibly well. It withstands temperatures up to 1800°C (3272°F). Other materials often fail at these levels. Alumina also resists chemical attack from many molten metals and slags. It stays strong mechanically under thermal stress. It handles electrical interference well too. This combination is vital for reliable temperature measurement in demanding processes.

How hot can these tubes actually get?
Maximum continuous use is typically 1600-1800°C (2912-3272°F). The exact limit depends on the specific alumina grade and purity. Higher purity alumina generally handles higher temperatures longer. Never exceed the manufacturer’s stated rating for your specific tube. Sudden temperature changes can also damage the ceramic.

Where do factories use these tubes?
You find them anywhere extremely high temperatures need measuring. Common spots include steel and glass melting furnaces, cement kilns, and ceramic sintering ovens. They protect thermocouples in heat treatment furnaces for metals. They are essential in environments with corrosive gases or molten materials attacking lesser materials.

How do you install one correctly?
Handle the tube carefully. Alumina is hard but brittle. Avoid impacts. Ensure the tube fits the thermocouple and thermowell snugly. Follow the manufacturer’s instructions precisely. Use compatible sealing materials if needed. Allow for thermal expansion during heating and cooling cycles. Proper installation prevents breakage and ensures accurate temperature readings.
