steel plate thickness for box supporting 4psi difference
steel plate thickness for box supporting 4psi difference
(OP)
Hello all,
I originally was thinking of making this from plywood but 4psi is too much for plywood. I have access to 4x8 sheets of steel 1/4 and 3/8". I would like to know which one I can get away with using for a 20"h x 13"w x 66"d box. There will be a 4psi difference inside the box vs. the outside. I am an electrical guy not structural so any help would be appreciated. I will be making a small altitude chamber for testing products.
Thanks

Hint: It will be much easier if you reinforce all 12 plate intersections with angle, since that will be where the problems are going to occur.

Really, the cheapest way for you to make this would be to use a piece of 24" Std Wt pipe with a pipe cap on one end. Then, you would only have one circumferential weld, it would hold the pressure with no problem, and you could still fit that size box in it (assuming the dimensions of your container were outside dimensions).

24" 3/8 scrap I can get for about $50/ft at a local scrap yard, varying lengths.
