Module 3 Process Piping Hydraulics Sizing And Pressure Rating Pdf ((full)) Page

Pressure-integrity design determines the and the pressure ratings for in-line components like flanges and valves. Process Piping Fundamentals, Codes and Standards

How to use this module (recommended workflow)

Seamless steel pipes usually have a manufacturing thickness tolerance of . The calculated must be divided by 0.8750.875 to find the nominal schedule thickness. Selecting Pipe Schedule Selecting Pipe Schedule = Allowable stress value for

= Allowable stress value for the pipe material at design temperature = Quality factor (weld joint efficiency)

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). High velocities can cause erosion, noise, and excessive

: Accounts for pressure drops in valves and fittings using the Equivalent Length Recommended Velocities

: Typical liquid velocities range from 3–8 feet per second (fps) . High velocities can cause erosion, noise, and excessive pressure drop, while low velocities may lead to sediment buildup. High velocities can cause erosion

Too high velocity causes pipe wall erosion, especially at elbows.
