For P-No. 1 Group Nos. 1 and 2 materials the extreme
fiber elongation may be as great as 40% when none
of the conditions listed below in (1) through (5) exist.

dear all
I would like to know about inpection the vessels.if we used vessels 15 year ago.I read code UG-25e say about use of telltale hole.How to do this case?
we calculation thickness of the head for small dia.
we met % Extreme fiber elongation - UCS-79(d) more than 5% for Material SA516-60 or 70 code require PWHT
if we used material SA234-WPB(CAP fitting) should be to PWHT or not?
thank you very much
we're designed the pressure vessels
material SA516-60
thickness 47 mm
we're have to PWHT and then should be Hardness. So I would like to know about reference to code for hardness and How much value hardness?
I am an new engineer. I'd lilk to know about compare between ASME section VIII div.1 2,3 Please clarification to me
Thank you for your kind cooperation.
