ASME Code on Pressurized Vessel inside a Pressure Vessel
ASME Code on Pressurized Vessel inside a Pressure Vessel
(OP)
I'm dealing with an unfired pressure vessel. One vessel is pressurized (internal) and nested inside of the other vessel (external).
The internal vessel will contain a pressurized chemical. The external vessel contains the internal vessel as well as piping and other components such as a pump. The interstitial space within the external vessel will also be pressurized. The pressure in both vessels is greater than 15 psig and less than 500 psig.
I am of the opinion that both vessels will require ASME stamps. I cannot find the chapter verse code section that provides guidance on this issue.
I appreciate the help.

one design one certification as a unit
ASME STAMPING AND CERTIFICATION as one unit design.
if one can be disassembled from the other then you can separately stamp each vessel.
safety is another issue: safety relief on the internal and external vessels are to be considered per Code.
