Brief introduction:
Zhengzhou Sanhui Co., Ltd selects high quality metal powder and technologic sintered in the hydrogen to produce

tungsten pipe

and other

tungsten product

s. Tungsten pipe is high purity and machinable. The crystal structure of tungsten tube is compact.

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..

Zhengzhou Sanhui Co., Ltd has complete equipments for testing physical properties. We test density, hardness, surface roughness, grain size, tensile strength and other parameters of tungsten pipe. The overal density of tungsten pipe is more than 18g/cm3 and the purity of tungsten pipe is no less than 99.95%.

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℃.
