Module 3: Process Piping Hydraulics Sizing and Pressure Rating
This comprehensive overview covers the core technical components of . This module bridge the gap between fluid mechanics and mechanical design, focusing on how to determine the optimal diameter and wall thickness for industrial piping systems. 🏗️ 1. Line Sizing Criteria
| Fluid Service | Economic Velocity (ft/s) | Erosion Velocity Limit (ft/s) | | :--- | :--- | :--- | | Saturated Steam | 80 – 120 | 150 | | Superheated Steam | 100 – 160 | 200 | | Pump Discharge (Water-like) | 8 – 12 | 15 | | Pump Suction (Water-like) | 2 – 4 | 6 | | Gas (Low Pressure) | 40 – 60 | N/A (Check DP) | Module 3: Process Piping Hydraulics Sizing and Pressure
Pipe roughness directly impacts the friction factor; rougher pipes cause larger pressure drops. Pressure Drop Criteria: Flow Rate : The flow rate of the
Corrosion Allowance:
Neglecting Always add 1.5mm to 3mm to your calculated thickness for longevity. Bernoulli’s Equation ) and to balance flow rate,
The Engineer's Workflow:
- Flow Rate: The flow rate of the fluid through the piping system, typically measured in gallons per minute (gpm) or cubic meters per second (m³/s).
- Pressure Drop: The decrease in pressure along the length of the pipe, typically measured in pounds per square inch (psi) or kilopascals (kPa).
- Pipe Size: The diameter of the pipe, which affects the flow rate, pressure drop, and energy loss.
- Fluid Properties: The density, viscosity, and specific gravity of the fluid being transported.
