Alumina ceramic pipe adopt isostatic pressing technology forming and sintering by high temperature. It has the feature of uniform composition, high density, high hardness, resistance to high temperature and high pressure, wear resistance and corrosion resistance etc. Alumina ceramic pipe is mainly as the material conveying equipment or the protector of other serious corrosion and wear equipment in fire power, mining, metallurgy, chemical etc .It can effectively prolong the service life of equipment.
Alumina ceramic pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, and other different shaped pipe.
According to the requirements of the customers, we can supply any specification of alumina ceramic pipe within DN300mm.
