High Temperature Industrial Thermocouple Protection Alumina Ceramic Pipe

High-performance 99% Al₂O₃ Alumina Ceramic Protective Pipe & Thermocouple Tube: tailored for extreme-

temperature industrial environments.

Tired of thermocouple tubes that fail under harsh industrial conditions? Our alumina ceramic thermocouple tube—

a premium structural ceramic solution—raises the bar for temperature measurement and insulation components.

Its unparalleled comprehensive properties make it the preferred choice for businesses that need stable, long-lasting,

and high-precision performance to keep operations running smoothly.

At its core is superior material quality. This tube delivers exceptional insulation and voltage resistance, with a volume

resistivity of 10¹⁴–10¹⁵Ω·cm at room temperature. Most importantly, it maintains reliable insulation even when

exposed to high-temperature stress—critical for protecting your electrical systems and ensuring safe, worry-free operation.

Alumina ceramic tubes of application:

1.Industrial Furnaces: Thermocouple protection tubes, furnace tubes, inspection tubes, rollers.

2.Semiconductor & Electronics:Diffusion furnace tubes, insulating sleeves, vacuum chamber components. 

3.Mechanical & Wear Parts: Wear-resistant linings, guide tubes, nozzles, sealing rings. 

4.Energy & Environmental: Fuel cell components, sensor protection tubes, sampling tubes. 

5.Laboratory:Tube furnace tubes, laboratory glassware.

Main advantage of the Alumina ceramic tubes:

1.Maximum tolerable temperature: 1600°C–1800°C,It does not soften or deform at high temperatures,

has a low coefficient of thermal expansion, and exhibits excellent thermal shock resistance.

Alumina ceramic tubes of Feature:

1.High Temperature Resistance: Can be used for extended periods at temperatures up to 1600°C or even higher (depending on alumina purity, such as 99% alumina).

2.High Hardness and Wear Resistance: With a Mohs hardness of up to 9, second only to diamond, it effectively resists particle abrasion and erosion.

3.Excellent Electrical Insulation: Maintains good insulation performance even at high temperatures, making it an ideal material for insulating sleeves.

4.Chemical Corrosion Resistance: Excellent resistance to most acids, alkalis, salts, and molten metals (except for hydrofluoric acid and high-temperature corrosion from strong alkalis).

5.High Mechanical Strength: High compressive and flexural strength, but is a brittle material with poor resistance to mechanical impact.

6.Low Coefficient of Thermal Expansion: Good dimensional stability and relatively good thermal shock resistance (but not as good as zirconium oxide).

7.Bio-Inert: High-purity alumina is harmless to human tissue.

Product Packaging
