We selects high quality metal powder and technologic sintered in the hydrogen to produce tungsten pipe and other tungsten products. 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..
We 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 tube is more than 18g/cm3 and the purity of tungsten tube is no less than 99.95%.
Suggestion: The tungsten pipe from JINXING should be used in vacuum or deoxidize atmosphere and the highest using temperature should be no more than 2450℃.
