Is it allowed to take tapping from the bottom flat eccentric reducer? In our plant, we have 24" elbow, 24"x20" eccentric reducer and de-superheater on a steam line (all fitting to fitting - without any pipe piece in between). Now we need to take tapping between the elbow and de-superheater. Consultant has given new design with 24" equal, 24" cap, a pipe piece between reducer and (now tee). New tapping to be taken from the new pipe piece. All this is costing us fortune (fittings, welding RT etc.) Can we take tapping from the bottom flat portion of the eccentric reduer? The tapping size is 6" with weldolet.
Other conditions, Ecc reducer A234-WPB schedule 80, line design pressure 25 bar and temp 360 degree Celcius.

My seniors in stress analysis are of the opinion that it is perfectly all right to take this tapping. But I wanted to take opinion from the learned people of this forum.
