Effect brazing steel-copper with R-600 application
Dear All,
In case of R-600 development, i want to asking about safety regulation.
as we know that refrigerator pipping consist of steel and copper tube.
If we want to apply R600,is still have a permission to brazing steel-copper ?
Because in IEC standard mention that different electron valency between 2 metal is forbidden to apply in R-600 (corrosion rate catalyst --> Leakage) .
In my opinion, no problem if we still use brazing steel-copper to R-600 application, because brazing spec Steel - copper is already defined, use flux and silver solder.
Need your advise,
Thank you,
Regards,
