vacuum tank ends

vacuum tank ends

(OP)
Hi All I have a 1974 bitumen rail wagon tank that I want to convert to a vacuum tank for unloading grease trap trucks. Its half inch wall 12mm and 6'8" (2000mm) diameter and 30' (10000mm) length but has no ends. I have 10mm domed ends quoted at$3200 each which are rated to absolute vacuum. The tank barrel is made in sections that are riveted together.
If I were to use flat plate steel on the ends to try and save some money how thick would it need to be?
I am in Australia. Thanks Terry

RE: vacuum tank ends

You need to contact someone local for the actual design work.

Note that to some extent, the thickness and details are going to depend on the code or standard used.

RE: vacuum tank ends

Off the top of my head, at 6'-8" and full vac, plan on about 4-inches.  Impractical.

Get an engineer to design something proper, like  ellipsoidal heads, or flat heads with structural stays.  Further, *you* have to define "vacuum".  Normal vac setups on tank cars only achieve about 1/2 atmosphere.  If you design to 'Full Vac', your heads will be twice as thick as 1/2-atmosphere.
