thank you all (sorry for my late thanks...i was busy)

metengr, did you refer to SA334Gr6 or SA210? Where can I found this value in ASME in order to explain that to my inspector?

Ok that's true, but I would like to know the minimum design temperature for SA334Gr6 and SA210.

Dear sirs, We would like to use stock tubes SA334 Gr.6 in a HE with design low temperature -46°C but in the certificate there isn't the value of impact test. Is it mandatory to write in the certificate the values of impact test? Shall we use these tubes without any problem? Another question...

Thank you all. Ivan

I agree (my client, too): "ASME code (no U stamp)" means "to be designed and fabricated in accordance with ASME, but neither stamped nor registered" I have a copy of Appendix 2 (addenda 06) but my interpretation is different (maybe ‘cause of my bad English). About hubbed flange: if I want to...

Heat exchanger ASME CODE (no U stamp) Can I use a plate (SA516Gr60) to machine a shell/channel flange? For a welding neck type? And for a loose type? Where is forbidden? ASME VIIIdiv1? Thank you all.

No, it's my first experience with nikel alloy. Thank you for the link. Now I realized :-)

Thanks. The material (plate) was supplied as "hot rolled + soft annealed", is there any results? Shall I point to my head former supplier something?

Maybe you refers to UNF-75 AND 79, but there I can't find any mandatory sentence about n04400. Could you help me? Thank you.

Sorry but I my ASME Review (2006) UCL stop at 60. And why UCL ? UCL refers to integral cladding, overlay cladding and linings... and this is not my case.

Head: material: SB127 UNS N04400 thk (after forming) > 6mm ID: 305mm Code: ASME (U stamp) Question: after COLD forming, shall I need any heat treatment? Normalizing? Which temperature? Where I can find some information? Thank you.

thank you All :-)

Dear All As concern the materials A 266 Cl.1 and A 350 LF1 , you are kindly asked if according to ASME Code there are particular requirements for two times Post Weld Heat Treated materials. Thank you for cooperation.

I need to upgrade my material database of ASME material used in a design software. I usually upgrade the database putting the value of maximum allowable stress. I find these values in stress tables (ASME II part D).

yes, ok, thanks, but I need the Y.S. table at temp. :-) and so I try in ASME IID. I need yield strength at 120 ad 60°C

What is the yield strength value for superduplex SA 182-F53 UNS S32750 ? I can't find it in ASME II D :-( thanks.

Yes, appendix 2. Thanks

increase clearance of the baffle/shell is ok only where clearance has no significant effect on shell side heat tranfer. See temaRCB 4-3.
