al2o3 ceramic pipes
Alumina Tubes is the the workhorse of the advanced technical ceramic tubes. It has good mechanical and electrical properties, wear resistance and corrosion resistance. It has relatively poor thermal shock resistance.
We mainly produce alumina tubes, rods and various industrial ceramic parts, which are mainly used in thermalcouple temperature, liquid steel continous temperature, various industrial furnace
