Alumina pipe is mainly used as lining of electric furnace to separate the heating element from burned material and seal the heating zone. Alumina pipe from ADceram is widely used in applications of equipment for coal, powder metallurgy and chemical glass test and analysis. Experiencing sufficient sintering, our pipes get resistance to corrosion and oxidation in high temperature as well as leakproof feature. The pipes are good at  straightness, accuracy and electrical insulation, and qualified under 1650℃.
