Hello to all,

I was searching for postings concerning Nozzle Loads, but I am not satisfied with what I have found, and I got confused along the way, so I made a new post for my question.

EXAMPLE:
W: Weight of pipe filled with fluid.
T1: Maximum operating temp.
T2: Minimum design temp.
T3: Maximum design temp.
P1: Operating pressure.
P2: Design pressure.
E1: Seismic
W1: Wind


LOAD CASES

L1: W+T1+P1 (OPE)
L2: W+T2+P2 (OPE)
L3: W+T3+P2 (OPE)
L4: W+P1 (SUS)
L5: W+P2 (SUS)
L6: W+T1+P1+E1 (OPE)
L7: W+T1+P1+W1 (OPE)
L8: L6-L1 (OCC)
L9: L7-L1 (OCC)
L10: L8+L5 (OCC)
L11: L9+L5 (OCC)
L12: L2-L5 (EXP)
L13: L3-L5 (EXP)
L14: L12-L13 (EXP)

When checking nozzle loads, which load case do we consider?

Do we consider only L1 for the nozzle loads or do we take whichever is greater between L2 and L3?

Do we also have to consider L6 and L7 for the nozzle loads?



Thank you,
