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

Target Velocities

: To avoid excessive pressure loss or erosion, engineers adhere to established velocity ranges: Pump Suction : 2–4 feet/sec. Return Lines : 10–15 feet/sec. High Pressure Lines : 20–25 feet/sec. Consequences of Poor Sizing : Module 3: Process Piping - Hydraulics, Sizing and

Module 3: Process Piping Hydraulics – Sizing and Pressure Rating

Here’s a structured, high-quality text that you can use as the basis for a PDF. You can copy this directly into a Word/Google Doc, format it, and save as a PDF. Step 7: Compare with allowable ΔP

• Focus: hydraulics fundamentals for process piping with practical sizing methods, pressure-rating principles, and selection guidance for materials and components. Designed for process, mechanical, and piping engineers working on chemical, oil & gas, power, and industrial plants.

Step 7:

Compare with allowable ΔP. Adjust diameter if needed. always remember: Run both calculations

Hydraulics gives you the diameter; pressure rating gives you the schedule.

Whether you are studying for an exam or designing a real chemical plant, always remember: Run both calculations, iterate, and never trust a pipe size that hasn’t been checked for erosion velocity and code-required thickness.

Process fluids often corrode metal over time.
