When sending nozzle loads to equipment vendors, should we send nozzle stiffness used as we have observed many pipe analysts use WRC-297 or FE/PIPE generated or some realistic nozzle stiffness instead of Caesar-II default stiffness for anchors or restraints, which may have some non-conservative effect on nozzle load; moreover, if we provide the six-DOF deflections from Caesar II results where we might have modelled the equipment from support by rigid element, the vendor can also verify whether our support end fixity for equipment supports or temperature profile assumptions match with their own thinking.

Nope.

On the subject of nozzle loads,
Provide realistic loads to the vendor, but be aware that expencive modifications can incour if your loads are too high. Best to have the vendor revert in the instance of non compliance with supplied loads.
