Line junction (tee) P&ID symbol

Line junction (tee)

ISO 10628-2 (group 25) / PIP PIC001 (line conventions)
Drawn as
A branch line meeting a run line in a T, with a solid dot at the junction.
Meaning
Branch connection: a tee, or a welded branch fitting (olet). A welded branch outlet (weldolet, sockolet) becomes olet. In plant.json, model a tee with the tee component and connect the run ends and the branch port.
Variants
  • The dot is often omitted on T junctions (a T cannot be a crossing)
  • Branch size may differ: reducing tee or olet
