Hi

I have the following quarries.

1. In API 610 nozzle allowable loadings, the force values are listed for different nozzle types. But the nozzle allowable moments are same for all three types of nozzles. Why is it so?

2. In a side discharge pump nozzle (nozzle inline with Z axis), i am analyzing with Y support and a Guide at the first elbow. In real situation for this support arrangement there won’t be any rotation about z axis. In that case if I provide a RZ restraint, is it represents the real support arrangement? If not on what support arrangements we shall use RX, RY, RZ restraint types?
