Hollow Ceramic Tubes High Temperature And Pressure Resistance Alumina Zirconia Tubes

Hollow ceramic tube has the advantages of high melting point and boiling point, high hardness, insulation at normal temperature, and electrical conductivity at high temperature.
 

Advantages:

1. Refractory.

2. Self Lubricating

3. Long Service Life.

4. Good Polished Surface.

5. Environmental and Healthy.

6. Superior Mechanical Strength.

7. High Corrosion and Wear Resistance.

8. Good Insulation Performance Precision.

9. High Temperature and Pressure Resistance.

10. High Purity Zirconia and Alumina Ceramic Material.

Due to these outstanding properties, Ceramic Products are used in a wide range of industrial and advanced appications.

And a lot of practical applications prove that our ceramic products has reached a state of high standard and quality.
