Module 3 Process Piping Hydraulics Sizing And Pressure Rating Pdf -

This paper outlines the core engineering principles for Module 3: Process Piping Hydraulics, Sizing, and Pressure Rating, covering the two independent design functions: fluid flow design (sizing) and pressure-integrity design (rating). 1. Fluid Flow Design & Hydraulic Sizing

• 20°C → 19.6 barg
• 200°C → 13.9 barg
• 400°C → 9.6 barg

• Laminar ((Re < 2000)) – Low velocity, high viscosity.
• Turbulent ((Re > 4000)) – Most process piping.
• Transitional ((2000 \leq Re \leq 4000)) – Avoid for critical systems.

• Thermal growth calculation and strategies: anchors, guides, expansion loops/compensators.
• Effect of thermal stresses on allowable pressure ratings and joint integrity.
