Pressure vessel wall thickness calculations
Pressure vessel wall thickness calculations
(OP)
Hi there,
**Wall thickness Required?**
I've been asked to design and manufacture a 100Bar Pressure chanmber. Basically the chamber will pressure test diver's watches to 100bar or approx 1000metres below sea level.
I will build the chamber from Stainless steel probably 316L as it has good overall corrosion resistance.
The chamber will be approximately 75mm diameter, and say 60mm high.
I was looking at a wall thickness of 15mm does anyone have the correct calculations anywhere?
Thanks
Satin

I'm actually British, it might be easier to look for the BS Standards on this matter.

First thing is that you can't expect to have your design done here.
Second and more important point is that you shouldn't worry only about the shell thickness; your vessel will need two heads, presumably a full diameter flange and at least one nozzle (assuming you will fill, vent and measure the pressure through the same attachment). To assess all these matters will require more engineering knowledge than what you seem to have available.

If you've been asked to design a pressure vessel for 100 bar, and you have no experience or knowledge of the applicable pressure codes in Europe, then you've been put in a very precarious situation.
I live in the states, but I know there are codes in England, equivalent to ASME, that govern pressure vessel design. Further, there are laws that require any design and manufacture meet those codes, so if a vessel isn't designed and manufactured (including stamping by some type of independant national board) per the requisite codes, you can be held criminally liable for any damage, injury or death which occurs due to negligence. Similarly, your system must be designed to certain pressure codes, not just the vessel.
I might suggest you be only the specifier of the equipment, and have both the vessel and system designed and built by a manufacturer that specializes in this type of equipment. Figure out what equipment is needed and put specifications together that cover each part. You will also need to find out what codes the various parts of the system must meet and incorporate them into your spec's.

I'm actually building the vessel for myself, I will have to look up the required codes.
