Product Details

Description of the China alumina ceramic tube


Ceramic - wear-resistant, ceramic - resistant composite pipe, ceramic composite steel tube. Ceramic composite steel tubes are manufactured by high - technology production process. The pipe from inside to outside, respectively by three layer, transition layer and steel corundum ceramics, ceramic layer is above 2200 ℃ high temperature to form dense alumina porcelain (AL2O3), with steel tube forming strong through the transition layer. Pipe for give full play to the steel tube high strength, good toughness, impact resistance, good weldability and corundum porcelain high hardness, high wear resistance, corrosion resistance, good heat resistance, overcome the steel tube of low hardness, wear resistance is poor, and the characteristics of the ceramic toughness is poor.
