It would be a great help if you can point me to the code reference.
The missing info.

Wall thickness of existing tee : 0.5"
Age of system : ~25...
We have a existing 36"NB LNG header and as part of the modifications to the pipework we need to have 16" branch connection on this line. Due to the layout constraints only possible location to have the bracnh is at a butt welded Tee.(See sketch attached). I am trying to find the code requirement...
Thanks for the responses
The single base plate I'm talking about

Any suggestions on the significance and guidance on when 2 ring plates are required ?
thanks and regards
Thanks for all the replies.
It turned out the nozzle is welded pipe and with the actual thickness(from ut report) ie without neg. tol ...
the blind is okay for the nozzle opening.

The design is as per PD5500. One option is using reinforcement pads. has anyone come across pads on blinds?
