Heater tube materials SA-249 vs SA-269
Heater tube materials SA-249 vs SA-269
(OP)
Hi, I'm working on the design of a heater & for several reasons in my country our supplier can't provide tubes with material SA-249 insted he's proposing the material A-269.
This last one is not listed in the ASME Code (as far as I know).
Does somebody know how can we deal with this?
Thanks

So, look for another permitted material like SA 213.

A269 doesn't require tensile testing; ASME B31.3 code requires separate tensile testing per A249
A 249 is not a listed spec. under ASME B31.3 piping code
A249 is connected with ASME Boiler & Pressure vessel codes such as ASME VIII-Div.1 and as such quite often applicable for heat exchangers, boilers, etc.
A269 is unlisted per ASME Pr vessel codes
A249 and A269 do have different tolerances on diameter and thicknesses
Design spec's + dictated design codes as per applicable project spec.s determine what you are allowed to use; not a supplier
