WRC 297 Limitation on Dn/Tn ratio
WRC 297 Limitation on Dn/Tn ratio
(OP)
Hi all,
Nozzle load calculation as per WRC 297 always gives an error regarding the Dn/Tn ratio.
I know that the ratio is not within the limit mentioned in WRC 297, but practically to get that ratio is not possible in most of the cases.
Wanted to know if this limitation is mandatory or have to go for FEA analysis for such nozzles?

In that case most of the Nozzles cannot be designed as per WRC 297, as this ratio is not possible to achieve in most of the cases
