Technical parameter in zirconia ceramic tube.
1. High mechanical strength
2. High temperature, Max working temperature: 1100C.
3. Good electrical insulation
4. Good chemical corrosion resistance under high temperature.
5. Excellent wear and abrasion resistance
6. Very hardness and Excellent thermal shock
Zirconia (ZrO2) is an extremely refractory material. Its strong resistance to the high temperature and high pressure, lower ratio of the moisture absorption, stable chemical properties, and its capacity of enduring the corrosion of acid, alkali, and organic solvent make it widely utilized in Petroleum exploration, Mechanical industry, chemical industry, natural gas, Medical equipment and environmental protection fields etc. Compared with alumina, it possesses excellent chemical inertness and corrosion resistance at temperatures well above the melting point of alumina.
Our zirconia ceramic tube diameter can reached from 0.65 to 100mm.
The tolerance in zirconia ceramic tube inside can reached 0.005mm
Customised is availbable and welcome.
