Problem:
Model piping connected to Nozzle mounted on Equipment (Floating head of an Air Cooler)?
Solution:
There are a number of modeling approaches that one may consider with modeling equipment. Nozzle connection to the Equipment:
1. Modeled as a rigid / flexible anchor
At the Nozzle flange or the base of the nozzle connected to the equipment enter a rigid / flexible anchor.
2. Take flexibility into consideration with Nozzle Element
Similar to AutoPIPE help section: Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Vessel. Consider modeling with a pipe element - add flange set elements - to pipe element - to Nozzle element - to rigid pipe element - to center of beam element.
3. Take flexibility into consideration with NodeLink Element
Insert a beam element to represent the equipment and restrain the beam using a number of supports (ex. Incline supports with Ultimate force gap, guide, rotational support, etc...). Insert a new segment starting at the surface of the beam / equipment. Next insert Piping to flange set and beyond to the field. Go back to the start of the segment and insert an NodeLink element with desired stiffness settings connected to the beam / equipment element.
4. Take flexibility into consideration with modeling all of the piping and equipment all the way back to the equipment supports using a combination of pipe, beam, anchor, etc.. elements
In this scenario, model the equipment using beam elements all then way to its supports locations (ex. an air cooler is typically supported by 4+ legs, imaged below).
Next, connect the piping to the equipment using one or more of the techniques mentioned above.
