A pipe's pressure rating is the maximum internal pressure it can safely contain at a specific operating temperature. Process Piping Fundamentals, Codes and Standards

Match the calculated inner diameter to a commercially available Nominal Pipe Size (NPS) and Schedule.

= Allowable stress value for the material at design temperature ( = Quality factor (weld joint efficiency, varying from

Pressure rating is about ensuring the pipe can safely contain the internal pressure. It's a structural design problem defined by ASME B31.3.
