Regarding the stress analysis report
Thread Content
I used CⅡ5.3 to enter the pipeline model, and I’m not sure which operating conditions should be considered in the stress analysis report, nor which condition should be used for determining the thrust on the pipe supports. I’m a beginner – how should I read a stress analysis report? I’m seeking advice from experts.
For pipe rack thrust, refer to the Restraints under OPE
Let’s learn together*. Get a good deal. Hehe
OPE, SUS, and EXP are generally the three operating conditions considered. The thrust on the pipe supports is definitely associated with thermal stress conditions, that is, under OPE conditions; under SUS conditions, it is mainly vertical loads, which are used to determine whether the pipeline supports are adequate. As for how to interpret the report, it’s simple: you understand fx, fy, fz, mx, my, mz, right? Just comparing these values is enough; if they are too large, it’s not acceptable, while if they are small enough, it’s considered a pass.
Stress type: SUS indicates the installation condition, OPE indicates the operating condition, and EXP represents a purely thermal state, including temperature and additional displacement. Result analysis: displacement refers to the nodal displacement, restraints refer to the restraining forces, and stress refers to the stresses. The pipe thrust is likely related to the restraining forces; it’s sufficient to consider both thermal and cold states. The nodal displacement can also be examined
