Can you clarify exactly what you are describing?

Are you dealing with inch or mm? (Either way, these are not standard, or off-the-shelf sizes)
What schedule is it?
What codes are you using? ASME / EN / JIS etc


I have never had occasion to use a 9x9x9 reducing tee.
but ...
The OD for a 9" pipe is 9.625"; 7" pipe is 7.625"
The ID is dependent on the wall thickness (Schedule).

Read this article: pipingdesigners.com/contents/tips-tools-...section-6a-pipe.html
(And everything else in the Tips, Tools & Training section )
Then come back with more questions.
