Hi, this is for a prototype project, it will not be welded.

O.D: 8"
Thickness: .125" nominal or something close
Material: 304/316 stainless
Type: Hemispherical Tank Head
Quantity: 2

Does anyone know where I could get this?

Thank you

A hemispherical tank head that small would be pretty unusual. While
one of the places others have mentioned could spin or press them, you
might find off the shelf hemispheres from a fabricator of hollow float
balls or decorative spheres. For example:

Isn't that size pretty much the size of standard air brake tanks on
trucks?

Probably in the right size range, but I think it's unlikely the heads
are hemispherical. I'm taking the OP at his word that what he needs is
hemispherical and not the more common ASME elliptical heads.

RB Wagner has them in 11 ga (0.120"), hemispheres and spheres, in 1010
steel, 304SS, 3003 aluminum, brass, and bronze. Go to
http://www.wagnercompanies.com/spher...mispheres.aspx. They do say
that these are for ornamental purposes and not recommended for mechanical
applications with tight tolerances. Give them a call and see if they are
good enough for you.

As are the barrels on the Tri-barrels.

Hi guys, thanks for the replies. Yes, heads 8"OD are common and I have
ordered some standard flanged and dished heads that size but we need a
much larger curve for our purposes. Unfortunately, since this seems to be
a special order item companies are not wanting to make such a small
quantity for us. I will keep filling out quote forms though and see what
turns up. I do like that decorative sphere idea, I will see what they can
do.

Is this "much larger curve" a standard geometric shape?

Explosive forming.. think auto-safety airbag, except steel.

Let us know where to go to watch the video.

I met someone who claimed to have hollowed out a stump....
Laid the metal over the hollow, added a couple pounds of black powder, and then dumped a couple yards of dirt over the top to give it some back pressure.
Touched it off, and formed a nice tank head.

Of course it was quite a one-up-manship fest at Bonneville.....

Thanks for the help. The Wagner hemisphere was
exactly what I was looking for.
