Review the analytical reports. If stresses exceed code limits, or if nozzle loads surpass equipment tolerances, modify the layout. Add expansion loops, shift guide supports, or introduce spring hangers until all stress, deflection, and force checks pass successfully.
A well-designed layout minimizes the need for expensive expansion joints. Key Factors in Stress Analysis (Lesson 1 Focus):
: Layout designer models the preliminary routing in 3D design software (e.g., E3D, S3D) based on the P&ID. Review the analytical reports
A layout designer must understand stress concepts to create routing that inherently minimizes stress. Waiting for a stress engineer to find flaws later in the design cycle causes costly re-work and project delays. 2. Primary vs. Secondary Loads
Small pipes should not be trapped between large, hot pipes, as the thermal movement of the larger lines can damage the smaller ones. Training Objectives and Testing A well-designed layout minimizes the need for expensive
Fix the pipe completely in all six degrees of freedom (three translations, three rotations). They isolate stress sections from one another.
The total mass of the pipe, valves, insulation, and the internal process fluid. Waiting for a stress engineer to find flaws
Piping stress analysis is the engineering discipline that provides the necessary technique to design systems without overstressing or overloading components and connected equipment. The primary objective is to prevent five major failures:
Several methods are available for pipe stress analysis, including:
