Flanges are rated by "Class" (previously known as "Pound" or "lb").

Example: NPS 4, Sch 40 (OD = 114.3 mm, wall = 6.02 mm), carbon steel (SA-106 Gr. B), ( S = 138 ) MPa @ 200°C → Max P ≈ 9.3 MPa (1350 psi).

Process piping transports fluids (liquids, gases, slurries) under various temperatures and pressures in industries such as oil & gas, chemical, and power generation. Proper hydraulic design ensures: High-viscosity fluids (e

Before sizing a pipe, one must understand the behavior of the fluid moving through it.

Resistance to flow. High-viscosity fluids (e.g., heavy oil) require more energy to move. Velocity (v): Speed of the fluid ( msm over s end-fraction ftsf t over s end-fraction 2.2 Flow Regimes (Reynolds Number)

focuses on the engineering fundamentals required to design these systems, ensuring they are sized correctly for hydraulic efficiency and rated properly for structural integrity under pressure. 2. Process Piping Hydraulics

Fittings, bends, tees, and valves alter flow direction and velocity profiles, causing additional pressure drops. These are calculated using two common methods: Equivalent Length Method ( Leqcap L sub e q end-sub their policies apply.

In conclusion, process piping hydraulics, sizing, and pressure rating are critical components of process piping design. By understanding the fundamental principles of fluid flow, sizing, and pressure rating, engineers can design safe and efficient process piping systems.

The second half of Module 3 shifts focus from the flow inside the pipe to the pipe itself as a pressure-retaining vessel. The primary objective here is to determine the minimum required wall thickness to safely contain the internal pressure of the fluid at its operating temperature. This process is governed almost universally in the process industry by the .

Before calculating diameters, you must understand how fluids behave within the pipe. Module 3 typically covers: The Continuity Equation
