Ceramic Heating Tube is the Main Products of Our Company.
Mission Ceramic is making high quality ceramic products.
We Are make 99.7% Al2O3 tubes, which max working temperature is 1800℃
and 95% Al2O3 tubes, which max working temperature is 1500℃
According to different usage, our tubes are widely used for furnace tube, thermocouple Protection tube, thermocouple insulator and other applications.
Advantage:
1.High purity: 99.7% alumina purity make sure high working Temperature.
2.Tight tolerance: we can grind OD to make tight tolerance for easy Insulation.
3.Fast delivery: we have large quantity tubes in stock.
4.Inspection: each single tube will be checked before shipping.
5.Low transportation cost: We have long time cooperated shipping Agency, which can provide very low prices.
Standard sizes.
