Plate thickness at the end of pipe. 1

[Squaric]

I'm struggling to find the plate thickness that I need to hold 10 bar in a 304l 2mm thick pipe. The plate will be welded on.

Can anyone pass on an equation to find the plate thickness?

Thanks,

Pete Hunt

Gen,
6mm = 1/4 plate and seems okay for the... I hope is water at 70-75F.
he's welding it to atube or rolled pc of sheet metal 2mm T.
if it washot water or others as steam, it would not pass but for water, no kiiling here.
I approve it.

It is not my pipe, not my signature.

Politely but firmly put, as I understand the geometry and pressures of his (mixed units!) proposal, I would not feel safe in a room or area near the piece being discussed, nor would I permit my construction crew to be near it under test pressure (! = 1.5 operational) and regular operational pressures. Even at low temp's and wet (none-compressible gas) conditions of temperature or fluid.

The tiny material savings of using "sheet metal", compared to the fabrication delays and difficulties of getting a sufficient weld deposit on between two thin-metal joints, then of testing and certifying such a little weld? Just buy a length of standard SS pipe, standard fittings. Get a result rated for the fluid pressures you have.

How are you going to attach pipe fittings to the sheet metal walls to let the gasses and test fluids get in and out of the fixture?
