RE: Hot Tapping
Someone needs add in here as I think OSHA has a procedure outline for hot tapping. We have our own which requires that we verify the integrity of the weld, either UT or RT and the thickness of the pipe. I would keep in mind the possible use of a slit tee which removes all stress away from the weld.
You mention no sizes or pressure/temperature. Below 4" there is equipment designed specifically for these sizes.
