Specification of High Purity Industrial Porous 99.9% Alumina Ceramic Protective Tube Thermocouple Ceramic Tube

This alumina ceramic tube protects thermocouples reliably. It uses high purity 99.9% alumina. This purity ensures excellent performance in tough conditions. The material resists very high heat. It handles temperatures up to 1700°C easily. This tube shields thermocouples from direct flame and hot gases. It stops damage to the sensitive sensor inside.

The tube features a porous structure. This design allows gases to pass through its walls. It prevents pressure buildup inside the tube. Pressure buildup could break the tube or harm the thermocouple. The porous walls let gases flow freely. This maintains measurement accuracy. It avoids false readings caused by trapped gases.

This ceramic tube resists chemical attack well. It won’t react with most molten metals or harsh chemicals. This chemical inertness makes it last longer. It also withstands sudden temperature changes. Thermal shock resistance prevents cracking. This is vital in industrial processes where temperatures shift fast.

The tube comes in standard sizes. Common outside diameters are 12mm, 15mm, 18mm, and 20mm. Wall thickness typically ranges from 2mm to 4mm. Lengths are customizable. Common lengths are 300mm, 400mm, 500mm, and 600mm. Other sizes are available on request.

Its high purity alumina construction provides electrical insulation. This isolates the thermocouple electrically. It prevents electrical interference. This ensures signal stability. The tube is mechanically strong. It offers good resistance to wear and abrasion. This durability suits demanding industrial settings like furnaces, kilns, and reactors. It delivers reliable protection for accurate, long-term temperature monitoring.

Applications of High Purity Industrial Porous 99.9% Alumina Ceramic Protective Tube Thermocouple Ceramic Tube

High purity industrial porous 99.9% alumina ceramic protective tubes shield thermocouples. These tubes are vital in tough industrial places. They handle extreme heat easily. Temperatures over 1700°C are no problem. This is critical for accurate temperature readings. The alumina purity is 99.9%. This high purity matters a lot. It means the ceramic is very stable chemically. It resists corrosion from harsh stuff. Acids, alkalis, and molten metals don’t harm it. This stability protects the thermocouple inside. The tube is also porous. This porosity is a key feature. It lets gases pass through the wall. This prevents pressure build-up inside. Pressure build-up could crack solid tubes. The porous structure avoids this failure. It makes the tube much stronger thermally. Sudden temperature changes are handled well. Thermal shock resistance is excellent.

These properties suit many demanding applications. They are perfect for molten metal temperature measurement. Steel, aluminum, and copper processing rely on them. The tubes work reliably inside furnaces. Different furnace types use them. Glass melting tanks need this protection. Chemical processing plants use them too. Highly corrosive environments demand such protection. Semiconductor manufacturing uses these tubes. High-purity processes require contamination-free materials. Power generation plants benefit from them. Boilers and turbines need precise, reliable sensors.

The result is long-lasting thermocouple protection. Measurement accuracy stays high over time. Equipment downtime is reduced significantly. Maintenance costs go down. Production efficiency improves. These tubes are a practical solution for extreme heat and corrosion. They ensure process safety and control. Investing in these tubes pays off through reliability.

5 FAQs of High Purity Industrial Porous 99.9% Alumina Ceramic Protective Tube Thermocouple Ceramic Tube

What’s this alumina ceramic tube made of?
It’s pure alumina ceramic. The purity is 99.9%. This high purity means it handles extreme heat and chemicals well. It won’t crack or break down easily.

How hot can this tube get?
It withstands very high temperatures. You can use it continuously up to 1600°C (2912°F). Short bursts can go even higher. It stays stable and protects your thermocouple inside.

Why does the tube have tiny holes?
The holes are intentional. They let gas pass through the tube wall. This is crucial for accurate temperature readings. The gas reaches the thermocouple sensor inside. The holes are small. They still block dust and ash effectively. Your sensor stays clean.

How do I install this protective tube?
Slide the thermocouple probe inside the tube. Seal the open end properly. Use suitable high-temperature cement or a compression fitting. Ensure the seal is tight. This stops unwanted air or contaminants getting in. The thermocouple tip must sit correctly within the tube.

Is this tube better than metal sheaths?
Yes, for extreme conditions. Metal tubes melt or corrode faster. They fail under intense heat or harsh chemicals. This alumina ceramic tube lasts much longer. It provides superior insulation too. Your temperature measurements stay reliable. Maintenance costs go down.
