Re: [PSUBS-MAILIST] Steel Pipe Hull



I purchased the program a couple years ago... version 4.08. Like any other program or algorithm though, you have to give yourself a wide safety factor... how much is your equipment/life worth?

I have the program from that website too - Deep Sea Power & Light) it was a free download from the website at one time. I was discussing an application for an underwater housing for a video cam that could be externally mounted on the sub. I was told they pulled that program, because it had a few glitches in it as well.

That is of course if we are talking about the same program. I'd have to find it.

For a low carbon steel alloy (70KPSI yield), 10" OD, 1/4" wall, 60" long,
"Under Pressure" (Deep Sea Power & Light) reports failure at 4145.1 PSI,
equivalent to 9277.6 feet of sea water.
