Tank or ASME Coded vessel ?

Tank or ASME Coded vessel ?

Tank or ASME Coded vessel ?

(OP)
To all,

I have a question about a process tank that a client wishes to have constructed. It is vertical axis, 8 foot diameter, 10 foot SS, and operates at 12 psig maximum. However, it will also have a half-pipe jacket that will operate at 50 psig ( steam in the half pipe)

The client(Texas refinery)insists that the unit does NOT require an ASME vessel design and ASME code stamp. ( The design and all materials will conform to ASME VIII) We believe that it does  require a stamp by the nature of the jacket operating pressure.

Question: I am not interested in opinions. Is there a specific Chapter and verse in the ASME Code or the Code interpretations that would clarify this situation ?

Again, no opinions....... Chapter and verse ?

Thank You

MJC

See U-1(c)(8) for the vessel and U-1(c)(9) for the jacket.
Your vessel is NOT to be stamped.
Oops, excuse me, this was an opinion!

RE: Tank or ASME Coded vessel ?

Hello all,

The ASME B&PV Code is a voluntary consensus Code.  Its use only becomes mandatory when it gets the "force of law" by being included in the State (or Commonwealth or Province or Parish) Code of Regulations (well, OK, there are some Federal Laws that should also be considered).  Of course not all of the US States have the pressure vessel Code (Law) in their Code of Regulations.  Tejas, for example, does not have a requirement for the use of the ASME B&PV Code FOR VESSELS (they DO for boilers).  

So, it is up to the owner.  Has nothing to do with the ASME Code - ASME is not the law in Tejas when it comes to pressure vessels.  As alluded to above, if there were a requirement for the use of the ASME Code for vessels in Tejas,  this would be a pressure vessel because of the half tube jacket (external pressure on the outside of the shell and positive internal pressure in the jacket).   Various "Pressure Vessel Laws" in different states sure make life interesting for all of us in pressure technology.

Don't mess with Tejas.  Hook 'em Horns.

Best Regards, John.
