ASME VIII div.1 allowable stress values for no-ASME II Part. D tabula
ASME VIII div.1 allowable stress values for no-ASME II Part. D tabula
(OP)
Hello everybody,
My query is quite simple for ASME seasoned engineers.
It has to do with the ASME VIII div.1 allowable stress values for no-ASME II Part. D tabulated materials. How could I estimate/calculate these allowable stresses? I'm currently using the 0,85/3 x Min.Tensile Strength, i.e for St.44-2 with Min.TS=410 MPa I use 116 MPa allowable stress for thickness calcution under internal pressure. Could someone direct me to a ASME VIII solid reference that verifies or negates my estimation.?
Thanks in advance,
Elias

Material shall be re-certified to an approved material in accordance with UG-10. Than you can use the stresses of the recertified material.
If non Code stamp fabrication , you could use non listed material . In that case the allowable stress shall be determined in accordance with table 1-100 of ASME IID.
e.g. lower of Rm/3.5 and Re(design temp)/1.5.

Thank you very much for your valuable reply.
I've checked the TABLE 1-100 in ASME II Part D that establishes for room temperature and above St/3,5 for wrought or cast ferrous anf non-ferous and 0,85/3,5 x St for welded pipe or tube,ferrous and nonferrous material. You quoted " lower of Rm/3.5 and Re(design temp)/1.5.", where did spotted that and what Rm and Re stand for?
Thanks again for your guidance.!
