Pure Tungsten pipe is mainly used to produce high temperature furnace thermocouple protection tube, also sapphire single crystal furnace and high temperature sintering furnace inner support etc
Tungsten pipes are usually formed by machining the forged tungsten bars. Fanmetal can also manufacture tungsten tube targets (tungsten rotating targets) forged and reshaped after sintering process or subjected to hot isostatic pressing.
