conflict between ASME code & PV-Elite about RT 32mm thickness

[mohsenmaleki]

Dear experts

thanks in advance for your kind attention,
My problem is:
table UCS-57 saye that for material P-NO.1 GR.1,2,3 for above 1 1/4 inch or for equal metric unit 32mm shall be full RT.Problem is if you work in PV-Elite 1 1/4 inch PV dont show any warning about UCS-57 but if you select metric unit(32 mm) PV suggest you full RT,
We are vendor and this comment has for us so much cost.I know the limitation for PV is 1.25*25.4=31.75mm but UCS-57 says that above 32mm(in the same row of 1 1/4").
We can use spot RT for exactly 32mm whitout regarding PV warning.Isn't true?
I hope to have your reply very soon.

Kind Regards,
M.Maleki

Dear Friend,

Use Code and apply Spot RT. Be consistent in units. PV Elite is showing Full RT requirement for 32 mm because it completely use customery values i.e. 32/25.4 = 1.26 which is greater than 1.25.

Never forget you are designing and fabricating vessel per ASME BPVC Code and not per PV Elite. PV Elite is only tool to help in design calculations and there may be error in that.
