Specification of High Temperature Aluminum Oxide Sleeve Alumina Ceramic Thermocouple protection Tube Pipe for Furance

These alumina ceramic sleeves protect thermocouples inside furnaces. They shield the delicate sensors from extreme heat and harsh conditions. Furnaces operate at very high temperatures. Ordinary materials fail quickly. Alumina ceramic handles this intense heat exceptionally well. Its maximum continuous operating temperature reaches 1700°C (3092°F). Short-term exposure to even higher temperatures is possible. Sudden temperature changes often crack materials. Alumina ceramic resists thermal shock effectively. This means it won’t easily break when temperatures shift rapidly.

The material is incredibly hard and dense. It offers excellent mechanical strength. This toughness protects the thermocouple tube from physical damage. Impacts and abrasion won’t easily harm it. Alumina ceramic is chemically inert. It resists attack from molten metals, slags, and corrosive furnace atmospheres. Acids and alkalis generally don’t affect it. This chemical stability prevents contamination. It ensures accurate temperature readings over time.

Common sizes are available. Typical inner diameters range from 3mm to 10mm. Outer diameters usually range from 6mm to 16mm. Lengths vary greatly. They can be several hundred millimeters long. Standard one-end closed tubes are common. Open tubes are also used. Threaded ends or flanges simplify installation. Custom sizes are often possible. High purity alumina (Al2O3) is essential. Purity levels are typically 95% or higher. Higher purity generally means better performance. These tubes are essential for reliable furnace temperature measurement. They extend thermocouple life significantly. They maintain measurement accuracy under severe conditions. Steel mills, glass factories, and heat treatment shops rely on them. They need dependable temperature control.

5 FAQs of High Temperature Aluminum Oxide Sleeve Alumina Ceramic Thermocouple protection Tube Pipe for Furance

High Temperature Alumina Ceramic Thermocouple Protection Tubes: Key Questions

What exactly is this product?
This is a protective sleeve. It’s made from aluminum oxide ceramic. It shields thermocouples inside very hot furnaces. The tube prevents direct contact with molten metal, harsh chemicals, and extreme heat.

Why choose aluminum oxide ceramic?
Aluminum oxide offers exceptional heat resistance. It handles temperatures far beyond what metals can withstand. It also resists wear and corrosion extremely well. This makes it perfect for demanding furnace environments. It protects the delicate thermocouple wires inside.

How hot can these tubes get?
These alumina tubes handle very high temperatures. They work reliably up to 1600°C (2912°F). Some special grades withstand even higher temperatures. This range covers most industrial furnace applications.

Will the tube crack from sudden temperature changes?
Alumina ceramic has good thermal shock resistance. It can handle rapid heating and cooling cycles reasonably well. This is crucial in furnace operations. Temperatures often change quickly. The tube needs to survive this without breaking.

Is it resistant to chemicals?
Yes, alumina ceramic is highly inert. It resists attack from many molten metals. It also resists most acids and alkalis. This chemical stability is vital. Furnace atmospheres can be very corrosive. The tube protects the thermocouple sensor effectively.
