Maximum Thickness of Pressure Vessel?
Maximum Thickness of Pressure Vessel?
(OP)
Colleagues;
Is there a maximum thickness a vessel head/shell can be under the rules of ASME Section VIII, Div.1? If so, is it further limited by material selection (ie; P1 may be thicker than P8)?
I don't know why, but I am under the impression that 8" is the maximum permitted for butt welding (forged vessels may be different) and you would have to consider going to a Div.2 or Div.3 design beyond that.
If anyone has a code paragraph to steer me towards will be appreciated.

I have worked primarily with carbon steel and SA-516-70. Section II, Part A, SA-516, paragraph 1.3 limits this steel thickness to 8". This is the number that was stuck in my mind.

We like to save money on material and labor to put that material together. Just a little more NDE stuff, but doing it anyway.
And engineering is cheap!
