A stub-in branch is fabricated by making a larger hole in the header pipe than the outer diameter of the branch pipe.
In the case of a Stub-in fit-up branch connection, the Edge of the branch pipe shares the same level of Inner diameter of the header pipe.
Stub-in branch is generally fabricated when the Branch Pipe diameter and run pipe diameter has a difference of more than one size.
Stub-on pipe connection is done by making a hole of size equal to the size of the internal diameter of the branch pipe on header pipe.
The branch doesn’t go inside the hole but stays on the upper surface of the run pipe only and the Stub-on pipe fit-up is done.
For “stub on,” the stub extends only to the outside of the main pipe.
Stub-on Branch is fabricated when:
