Is the calculation for tube thickness with a negative internal pressure the same as for posative internal pressure(pd/f). Can't remember this one and all texts only do formulaes for posative internal pressures, nothing showing an external pressure.

This formula is the same. The p is just the pressure difference. Fact is though, that you will have to check stability against imploding as well. For this a different criterium is necessary. I haven't got that in my active mmemory, but you should check a technical handbook or the internet on that. In german the term is "beulen" in english I do not know.
