Hardness Test

[MirjafariSM]

Hi Dears
Is hardness test necessary for welding area(HAZ) of none pressure parts such as Column internals, trays etc?
(Our applicable standards are ASME SEC VIII,IX and NACE -MR0103)

 

[SJones]

If the requirements of MR0103 have been contractually imposed upon the internals as well as the pressure envelope materials, then the answer will have to be 'yes - as directed by MR0103'. Ascertaining whether MR0103 should have been applied to the internals in the first place is best addressed by an FMEA and subclause 1.2.1 of the NACE standard.
