Re: [PSUBS-MAILIST] Steel Pipe Hull



Thats correct, there are formulas for this. ABS got one that is nice
and pretty understanable.

Ok, it's the same question as before but without the "F-glass" word that
killed the vis last time around.

Lets say we are building a 1ATM battery box. If a steel pipe is rated at
1000 psi.  The same pipe without frames, will not be able to withstand 1000
psi of external force due to problems with roundness.  But there must be
some ratio or formula that can define this loss of performance for any given
diameter, plate thickness and roundness.

Does that make sense, and isn't there some chart that mechanical engineers
use for this when building all the piping that passes through pressure
vessels?  Where is that chart?
