Pipe Branch reinforcement

I am looking for a spreadsheet or notes
that can be developed into a spreadsheet for
calculating branch pipe stub-in into main header pipe at 90 degree and lateral

Try ASME B31.5 for refrigerant piping or B31.3 for process piping. The procedure is covered in both of these standards.

please help me if we can use T joints istead of y branch in ref. piping vrv system
