Goodmorning to everyone!

I'm starting a new project using the standard UNI EN 12516-2 ( Shell design strenght : Calculation method )but while I was trying to calculate the wall thickness of the globe valve body i encountered a problem. In the point 7.2.2.1 ( pag. 9 ) are there two symbols not so clear for us.
do = outer diameter or radius
di = inner diameter or radius
The body is a globe body valve.
Does anyone know which are these two dimensions in a globe valve body?

thanks in advance
