There are 3 different types of nozzle connections on different vessels.
Mentioned below are the details of nozzle connections: -
ACCUMULATOR VESSEL SHELL
2" (with RF pad) & 6" (with RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1 (with RF pad).
ACCUMULATOR VESSEL DISHED HEAD
1" (without RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1. The connection is similar to FIG. L-7.7.1 of ASME Section VIII Division 1. The only difference is that in our case the nozzle connection is SET-IN whereas this figure shows SET-ON connection.
3" (without RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1.
DESANDER VESSEL SHELL
6" (without RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1.
DESANDER VESSEL DISHED HEAD
3" (without RF pad) & 6" (without RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1.
1" (without RF pad) & 2" (without RF pad) - FIG. UW-16.1 (c) of ASME Section VIII Division 1. These connections are similar to FIG. L-7.7.1 of ASME Section VIII Division 1. The only difference is that in our case the nozzle connection is SET-IN whereas this figure shows SET-ON connection.
