Module 3: Process Piping Hydraulics, Sizing, and Pressure Rating

Guide to Module 3: Process Piping Hydraulics, Sizing, and Pressure Rating

1. Introduction

Module 3 generally focuses on the relationship between fluid flow, pipe geometry, and pressure integrity. The objective is to ensure that process fluids are transported efficiently (hydraulics) within a conduit that can withstand the internal forces (pressure rating) and is economically sized (sizing).

• Sizing a chilled water line for 400 gpm at 200 ft head available.
• Selecting pipe schedule for saturated steam at 150 psig.
• Determining if a 10″ existing line can handle a 30% flow increase.

• 🟦 Blue = Hydraulics theory
• 🟩 Green = Sizing procedures
• 🟥 Red = Pressure ratings & safety

6. Common Mistakes & Mitigation

| Mistake | Consequence | Mitigation | |---------|------------|-------------| | Ignoring viscosity | Underestimates ΔP | Always check Re | | Using average velocity in gas lines | Large ΔP error | Compressible flow equations | | Neglecting temperature derating | Overpressure rupture | Use design temp. + 25°C margin | | Oversizing without economic check | High capital cost | Run ΔP vs. cost trade-off | Sizing a chilled water line for 400 gpm
