Piping must have enough flexibility to handle expansion at high temperatures. 5. Conclusion and Best Practices

serves as a critical guide for designing safe and efficient fluid transport systems. This module bridges the gap between theoretical fluid dynamics and the practical application of the ASME B31.3 Process Piping Code The Core Objectives of Module 3

The allowable stress S decreases as the operating temperature of the piping system increases. A pipe that is safe for a high pressure at room temperature may not be safe at an elevated temperature. This is why the is just as important as the design pressure in the calculation.

From ASME B31.3, Eq. (3a): [ t = \fracP \cdot D2(SEW + PY) ] Where:

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 .

The primary method for calculating frictional head loss in a pipe is the Darcy-Weisbach formula:
