For pipes no need to rating and thickness (corrosion allowance,mil tolerance,....,included) should be calculated.
For flanges ratings are needed.
Refer to:

ASME B31.3 for pipe and B16.5,B16.47 for flanges

Get the piping designed as per ASME 31.3 (for process piping).

For any quick solution, you may contact me. I have the spreadsheets available for the same.
