Module 3 is arguably the most important part of process piping. Getting the diameter wrong means your pump fails. Getting the pressure rating wrong means a rupture disk blows—or worse, a gasket fails.
Where:
A better PDF will provide a solved example for a real-world scenario: "Size a 200-foot carbon steel line pumping 500 GPM of crude oil at 120°F with a maximum allowable pressure drop of 10 psi." It will walk you through friction factor (using Moody’s chart or Swamee-Jain formula) and then show you how to iterate between nominal pipe sizes (NPS).
: Components like flanges are often selected based on standard ASME B16.5 pressure-temperature rating classes (e.g., Class 150, 300, or 600). 3. Key Design Considerations
ASME B31.3 is the bible, but it is dense. A better Module 3 translates that code into a simple hierarchy:
The schedule (Sch) indicates wall thickness. Common schedules: 10S, 40, 80, 160, XXS.
