Applications of tungsten pipe:
Tungsten pipe is mainly used to produce high temperature furnace thermocouple protection tube, sapphire single crystal furnace and high temperature sintering furnace inner support etc..
Suggestion:
The tungsten pipe from Zhengzhou Sanhui Company should be used in vacuum or deoxidize atmosphere and the highest using temperature should be no more than 2450℃.
