Nozzle design for lethal service
Nozzle design for lethal service
(OP)
Dear all,
I searched several places and did not find nozzle has to be integrally reinforced nor radiagraphable design for category D joint per code for lethal service. Only full penetration weld is needed. Do I miss something ?

RE: Nozzle design for lethal service
You are correct in saying that only full penetration weld is required by the Code. Integral reinforcement or radiographable nozzles (i.e. lip type or Q-type nozzles) are just preferences.
The following ASME interpretations indicate that nozzles with separate reinforcement plates are allowed.
