A pipe system is the same as a pipeline in a facility and main equipment like
column, heat exchanger, reactor, pressure vessel or pump is entered as
from-object for this pipe system. It is usually not recommended to enter
from-object relations on secondary equipment (valves, ventilation, drains,
measuring equipment and so on) on detailed pipe segments. It's more common to be

This structure could be created in two different ways:
