PWHT "Nominal Thickness"
PWHT "Nominal Thickness"
(OP)
I am attaching a nozzle with a through fillet (P-1 material), the sizes of the fillets are 3/4" on one side and 7/8" on the other, there is abate in the office as to whether this has to PWHT or not, it looks to me under UW-40(f) that the nominal thickness is taken as the largest fillet, another argues its the sum of fillets, can somebody help clear this up?
.Thanks
.Thanks

RE: PWHT "Nominal Thickness"
To me "the throat dimension" indicates one weld is used, it doesn't say "dimensions", or "the sum of" also after that it indicates that if a groove and fillet are used then take the nominal of only one of them (the one with the greatest thickness). I would think if they wanted the sum of the fillet wleds to be used then they would say that, but they simply say the "throat dimension", again singular.
