5 FAQs of Al2o3 Alumina Ceramic Tube Pipe Bushing Sleeve for Thermocouple

Here are 5 common questions about Al2O3 Alumina Ceramic Tube Pipe Bushing Sleeves for Thermocouples:

What is this ceramic sleeve made of? It’s made from aluminum oxide, called Al2O3 or alumina. This material is very hard. It withstands extreme heat well. It resists chemical corrosion effectively. These properties make it ideal for protecting thermocouples.

How hot can these alumina sleeves get? Alumina ceramic handles very high temperatures. Standard grades work reliably up to about 1600°C (2912°F). Special high-purity grades can manage even higher temperatures, often exceeding 1700°C (3092°F). This makes them suitable for demanding industrial processes.

Why use alumina instead of metal tubes? Metal tubes conduct heat fast. This can cause inaccurate temperature readings. Alumina ceramic is an insulator. It conducts heat poorly. This insulation protects the thermocouple. It ensures more stable and accurate temperature measurements. Alumina also resists chemical attack much better than most metals.

What sizes and shapes are available? These sleeves come in many sizes. Common shapes include straight tubes. Bushings are also common. They fit various pipe diameters. Custom sizes and configurations are often possible. Check the specific product specifications for exact dimensions and bore sizes.

How do I install and handle these sleeves? Handle alumina ceramic carefully. It is strong under compression. It is brittle against impact or bending stress. Avoid dropping it. Avoid forcing it into place. Ensure the fit allows for thermal expansion. Use appropriate sealing methods if needed for the application. Protect the thermocouple wire during insertion.
