U stamp required for this vessel?
U stamp required for this vessel?
(OP)
Hi All,
I would like to confirm something in U stamp requirement to a small pressure vessel.
The design pressure is 125 psig
The shell will be 12 inches pipe sch40
Ends will be cap in sch 40.
Length of the shell will be 4 feet.
Per my understanding to U1(c)(2)(i) of ASME VIII-1, it is within the scope of VIII-1, the stampe is required.
Any comments will be appreciated.

Yes, your interpretation is correct. If you are getting the argument that it is built of piping components and thus is a pipe, take a look at Interpretation VIII-1-04-46 in Volume 56, 2006.
