Problem:

There are various types of end connections on Vessels and Tanks:

• • Dished only
  • Elliptical
  • 80% Dish 10% Knuckle
  • Reversed Flanged
  • Flanged only
  • Shallow Flanged
  • Hemispherical
  • Toriconical
  • ASME Flanged
  • Standard Flanged
  • Conical

How to model piping connected the end of a tank / vessel in AutoPIPE?

Solution:

The technique is the same regardless of the Vessel's / Tanks's end type head construction. However there are 3 modeling approaches. 

1. Consider the Vessel / Tank piping connection as an Flexible / Rigid anchor

2. Take credit for the flexibility in the tank construction, insert a Nozzle component then anchor element

3. Model the entire vessel / tank, add piping to surface with rigid piping

See the following procedure and choose one or more techniques to use in your model:  

1. Use an Anchor Element

Assume the piping connection to the tank / vessel is considered an anchor component. Insert an Anchor element as needed.

2. Insert Nozzle Element and then Anchor element

Please see the following AutoPIPE help section:
Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Nozzles

Hear are 2 examples of connecting piping to a tank / vessel using a nozzle element. 

3. Model the entire tank / vessel

Please see the following AutoPIPE help section: 
Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Vessels

Note: in order to connect a pipe at B02, follow the techniques in option #2 above (omitting the anchor of course)
