Heat Treatment Requirment for PV

Heat Treatment Requirment for PV

Heat Treatment Requirment for PV

(OP)
May you please advise whether there is ASME VIII Div. 1 requirement for heat treatment of -50 ºF (or lower) design temp. vessel?

Thank you very much in advance.

RE: Heat Treatment Requirment for PV

Could you please provide more background information related to your question?

RE: Heat Treatment Requirment for PV

The -50°F issue is more related to material selection than to PWHT. PWHT will be resulting from the material choice and service conditions.

RE: Heat Treatment Requirment for PV

Code PWHT is generally based on thickness. If you perform Non-Code PWHT it is possible to reduce your MDMT by an addition 30 degrees F (see UCS-66(c)). Lets say you build a vessel that doesn't require Code PWHT and you have impact test excemption down to -20F. Your client now want -50F. You perform PWHT and you get -50F without impact testing.  

RE: Heat Treatment Requirment for PV

Sorry, thats UCS-68(c)

RE: Heat Treatment Requirment for PV

I knew I was missing something, codeeng.

That requirement is only good for P1 materials.

And I still don't know what the original question was...
