Product content
The wear-resistant ceramic composite tube is corundum ceramic (a-AL2O3), which is a single stable crystalline structure. Therefore, the composite pipe can operate normally in the temperature range of 50-700℃ for a long time. The coefficient of linear expansion of the material is 6-8×10-6/0C, which is about 1/2 of that of the steel pipe. The material has good thermal stability. It has the characteristics of high wear resistance, long service life, convenient installation and remarkable economic benefits.
