Lifting Lug Material Allowable stress

Lifting Lug Material Allowable stress

Lifting Lug Material Allowable stress

(OP)
I am curious to know why allowable stress for lifting lugs are matched with that of shell or head ? Aren't we required to use the allowable stress @ normal atmospheric temperature i.e 70F or MDMT as vessel rarely experiences design temperature while being lifted ? Thanks

RE: Lifting Lug Material Allowable stress

After it's Code-Stamped, it's an ASME vessel, so it seems logical to design for a consistent set of stresses.  Yes, I would vote for the use of the allowable stress at ambient conditions (say 100F).

RE: Lifting Lug Material Allowable stress

The default allowable stress values applied by COMPRESS are taken as for ambient temperature. See discussion at http://www.codeware.com/support/faq/1054.html
