Product Description

High temperature ceramic pipe for wholesale 


Description
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. 

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
