1. The problem statement, all variables and given/known data
If I'm looking for standard sizes of nozzle thickness.

2. Relevant equations

3. The attempt at a solution
Should I be searching for the standard thickness of plates that are used to form the nozzle?

The specification talks about using 4" pipe and 6" pipe for "nozzles", but provides no other details.

Usually, a drawing accompanies such a specification to provide the necessary details from which a cost estimate can be prepared.

Both pipe sizes are given as Schedule 80, the wall thickness of which can be obtained from a standard pipe size chart:

thanks, I also have a question about the shell design. I have an equation for the minimum required shell thickness
$\frac{P(R_{design}+corrosion)}{SE-0.6P}$

but I'm not given R_design. should I guess an R_design? what should I look at to check if the guess is a good estimate?

This is a pressure vessel so you will need to design shell , nozzles and other components to appropriate ASME codes .
