Description
Brife Intruduction
We are make 99.7% Al2O3 tubes, which max working temperature is 1800ºC
and 95% Al2O3 tubes, which max working temperature is 1500ºC
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.
Warranty
1. If any broken during shipment, we will send replacement for free or send back your payment. (In case we arrange the shipping).
2. If tolerance is not same with what we discussed, we will send replacements.
3. Standard sizes.
