What is the maximum pressure that a %99.9 pure tungsten tube can withstand?

[achilles89]

I have been looking all over the web and can find nothing...How do I calculate this? Please help if you can..thankyou

I think the ultimate tensile strength of pure tungsten is about T = 100,000 to 500,000 psi, or 80,000 to 100,000 psi, depending on source.

If the tube diameter is D, and the wall thickness is t, then the maximum internal (differential) pressure is P = 2T·t/D.
