external pressure vessel calculations

[buddy]

need an equation for (external) crushing pressure of pipe

Hi Duddy,

Load x area = failure if only we knew material, diameter, thickness, length, load, point or distributed, ad infinitum. {sigh} Really?

If you can you tell me the length of this piece of string I will give you the answer and a thousand dollars cash. No, make the ten thousand.

I simply need the equation.... not have it solved for me.
There are conflicting view points
The tube is machined to its size not a pipe or tube in the conventional sense (quite different properties than seamed of seamless)
the operating external pressure is 20,000 psi @350 deg.
material is nitronic-50 ss
The name is buddy not duddy

Pressure Vessel External Pressure Calculations

Be aware that the equations and very general in nature -
