Product Desciption
1800c High Temperature Alumina Al2O3 Pipe
The main material of ceramic pipe is Aluminium Oxide( Al2O3). The purity varies from 60%-99.7%, density from 3.0-3.9g/cm3, and working temperature from 1000-1700ºC. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance.
Alumina pipe Features and advantage
Great mechanical strength
Low thermal conductivity
High heat resistance
High softening temperature
Small thermal expansion coefficient
Good cold-resistance heat-resistance
Resistance to acid and alkali corrosion
Long service life
Alumina pipe Technical Index
There are 3 categories accorind to Alumina content and features: Common ceramic pipe, Al2O3<75%; High Alumina ceramic pipe, Al2O3 75%-90%; Corundum pipe:Al2O3>90%.
After comparison,their features are as below:
