Hi ,
can anyone tell me if you can have Z245.12 flange that is dual rated for 359 CAT II and 290 CAT II? Would the stamping on show 359 CAT II therefore covering 290 CAT II? I have a supplier saying this flange is dual rated.
Hi ,
In ASME IX the weld procedure qualifies a certain thickness range.
In Z662 I can find the thickness range for qualification of welders but not for weld procedures. Does Z662 have something that shows what thickness the weld procedure is qualified to?
