Steel plate deflection

Hi Experts

I am looking to create a rectangle pressure tank. 12 inches x 12 inches x 96 inches.

I would like to understand how thick the steel plate would need to be to have minimal deflection under 100PSI

I invision using two wider plates so an adequate weld can be done along edges.

Thanks in advance for you thoughts

Hi Bill,

Flat sided pressure vessels are not a favorite of any design. Can you not use a pipe of similar volume?

Thanks for your interest. I can not use a pipe for this application. I understand the difficulty of this type of vessel compared to a pipe.

It is difficult to find information and I need some help.

Thanks Bill

Bill, there is a dearth of information for obvious reasons when trying to make a flat-sided pressure vessel. Many things need to be considered for the design, the working temperatures, internal or external bracing, safe working pressure (100-psi) will be around 1/2 design pressure, pressure relief valves and settings, safety-burst panel(s), material grade, material preparation prior to welding, rust accumulation and metal degradation over time, weld security, all 32-feet of it by a Certified Welder, then X-Ray validating etc. The list will go on and on.

Also you need to consider local Codes and Certification of pressure vessels for your County/State.

IF you are still hell-bent on flat plate, then I suggest you contact a local Engineer for design. It is a project slathered with risks.

Thanks for your suggestions

What is the medium, liquid or gas and what temperatures?

Hi

The gas is compressed air. Operating range would be 70-85 degrees F.

Thanks for your interest

Bill,

This not just welding plates together. If that were done , you would need plates in excess of 1 inch thickness range to sustain the stress alone.

You need a structural professional to design support straps, etc, not something we do here.

Thanks for everyones response.
