Thermocouple Protection Alumina 99 Al2O3 Ceramic Tube

 

Product Description

 

The main material of ceramic tube is Aluminium Oxide( Al2O3). The purity varies from 60%-99.7%, density from 3.0-3.9g/cm3, and working temperature from 1000-1800°C. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance.

 

ceramic tube Features and advantage

1.Great mechanical strength

2.Low thermal conductivity

3.High heat resistance

4.High softening temperature

5.Small thermal expansion coefficient 

6.Good cold-resistance heat-resistance

7.Resistance to acid and alkali corrosion

8.Long service life

 

ceramic tube common series

1. Protector tube series

Material: Corundum  

Use: Protector tube and temperature tube of thermocouple thermometer, carbon determinator, sulfur deteminator and combustion pipe of metallurgy, iron and steel, chemical analysis.

Feature: Great mechanical strength, good thermal conductivity, great resistance to heat impact, high softening temperature, good insulation and high-frequency characteristics under high temperature and resistance to chemical corrosion.

 

2. Insulation tube series

Material: Corundum

Use: For thermocouple, interval and insulation between couple wires. For specifications, there are single hole, double holes, four holes and multi-holes. For form, there are round and oval pipes.

Features: Great mechanical strength, good resistance to thermal impact, good insulation and high-frequency characteristics under high temperature. Breakdowm voltage and volume resistance and self-reactance are great and thermal expansion coefficient is small.

 

3. Through tube series

Material: Corundum

Use: Inner liner tube and heating tube in electric furnace, heat treatment furnace and toughened furnace, chlorine pipe for production of alchlor and electric heating pipe in the tin trough in the production line of float glass.

Features: Great mechanical strength, good resistance to thermal impact, high softening temperature, good chill and abrupt heat properties, small thermal expansion coefficient and resistance to acid and alkali corrosion.
