How to model tee or cross ASME B16.11 fitting

good morning,
I should model an ASME B16.11 class 3000 tee fitting and would like to ask how.

In this case we have: 2 "header and 1" branch, tee threaded type and hex head bushing reduction type, I thought to create the following modeling example:

  

O01: header 2 ", length 1000 mm, thickness 3.2mm;
O02: run (for tee header) 2 ", length 64 mm (note A of the manufacturer's scheme) and thickness 7mm (note G of the manufacturer's scheme);
O03: run (for tee header) 2 ", length 64 mm (note A of the manufacturer's scheme) and thickness 7mm (note G of the manufacturer's scheme);

P01: run (for tee branch) 2 ", length 64 mm (note A of the manufacturer's scheme) and thickness 7mm (note G of the manufacturer's scheme);
P02: reducer 1 "(hex head bushing reduction) length 22 mm
P03: branch 1 ", length 1000 mm

moreover
for the tee type I selected: FITTING; 1,
in the threaded connection points I inserted a user SIF (O01, O03 and P02) see below:


is it a correct approach?
Thank you
