Detailed
 
Tungsten Tube/ Pipe:

 
Features:
1.Surface: silver gray metallic luster;

2.Purity: 99.95% MIN;

3.Density:18.8g/cm3 MIN;

4.Production processes: isostatic pressing, IF induction sintering, CNC vertical turning, CNC milling, coreless grinder and wire cutting;

5.The tungsten tubes we produced are with high-precision, finish surface, straight size, and high temperature deformation.

6.There are two kinds of tungsten tubes: one is with diameter 8--70 mm, wall thickness more than 3mm, maximum length 300mm and density no less than 18.8g/cm3. Another one is with diameter 70—500mm, wall thickness more than 8mm, maximum length 700mm and density no less than 18.3g/cm3.
 
Application:
Tungsten tube is widely used in the thermocouple protection tube, sapphire crystal furnace and high temperature furnace, etc. Tungsten is usually sintered processed and with 8mm wall thickness. Tungsten tube contributes stability to the hot zone. While high in thermal inertia, tungsten tube may prolong the growth cycle of the sapphire. The maximum wall thickness of one that rolled from tungsten plate is 2mm with low thermal inertia. But they are not as reliable and durable as normal ones.
