Hydraulics Sizing And Pressure Rating Pdf Exclusive [portable] — Module 3 Process Piping

Process piping systems are the veins and arteries of the chemical, petrochemical, and power industries. Proper design is critical, not only for ensuring that fluids get from point A to point B but for the safety, efficiency, and longevity of the entire plant.

This exclusive content is typically divided into two fundamental chapters, which we will explore in detail: Process piping systems are the veins and arteries

| Symbol | Term | Description | | :--- | :--- | :--- | | | Minimum Required Thickness | The theoretical minimum wall thickness needed to contain the pressure. | | P | Design Pressure (psig) | The internal pressure to be contained. | | D | Outside Diameter (OD) of Pipe (in) | The standard outside diameter. | | S | Allowable Stress (psi) | A material property that de-rates with higher temperatures. | | E | Weld Joint Factor | Accounts for the strength of longitudinal seam welds (1.0 for seamless pipe). | | Y | Temperature Coefficient | A de-rating factor for materials at high temperatures (0.4 for most steels). | | CA | Corrosion Allowance (in) | An extra thickness added to the pipe wall to account for expected material loss due to corrosion or erosion over the life of the plant. |
