Hello all,
I'm having a touch of difficulty with modeling practice around tee nozzles like the below arrangement:
My first attempt was to run N2 first as a straight nozzle off the bolted cover, with a secondary nozzle then run off this for N7. However one can't correctly model the tee and it's materials this way, N7 can only be run as a set upon pipe connection to the N2 riser ("with or without re-pad) . A tee isn't allowed for the nozzle connection as the model is still referencing the DN450 shell dimension from the shell below this top nozzle connection and a DN450 tee won't fit obviously (nor do we want to insert one)
The second attempt was to run a "dummy shell" in the same material as the nozzle stub and then insert a tee'd nozzle for N7. This works fine for N7 but then I am unable to run N2 either by running off the vessel shell or the N7 nozzle as a reference. It accepts my input and renders in the 3D view but doesn't show in the 2D view and strength calculations won't run. See below:
Has anyone butted up against this before? Is there a neat way to model this that I'm missing altogether?
Thanks in advance, Grant
Hello Grant,
Such design is not possible with AutoPIPE Vessel, the main purpose of AutoPIPE Vessel is to consider nozzles as openings to check openings created in the vessel.
To have the correct calculation, you must create two models.
One model with an opening on the cover.
A second model with the tee to check the additional assembly.
