Pipe Stress Analysis using CAESAR II Full Crash Course

Open Caesar II, use the configuration editor to set database definitions and units, allocate memory, and create a new model named Udemy course for piping input.

Model the first pipe element in Caesar II, selecting node ten increments and inputting diameter, wall thickness, and fittings. Set ambient temperature, axis orientation, and design versus operating pressures.

Model and verify pipe fittings in a 3d model, including bends, tees, and reducers, with emphasis on accurate reducer dimensions and centric alignment near pumps.

Model valves and flanges in Caesar II by selecting valve types from the built-in library, setting flange weight and class, and enabling flange leakage checks.

Modify dimensions and stretch sections, then copy, paste, and mirror pipe branches using select group and duplicate in Caesar II to avoid re-drawing.

Learn to model rigid anchor supports in CAESAR II, set node-based restraints with gap and friction, and appreciate how boundary conditions and installation material shape pipe movement.

Learn how to model trunnion supports at a vertical bend in Caesar II, creating a rigid, ground-connected pipe support that limits piping flexibility at the bend.

Learn to model and design hanger supports in Caesar II for pipe stress analysis, choosing flexible versus rigid supports, using vendor libraries, and interpreting output reports.

Model a steel structure in Caesar II to reflect beam stiffness and deflection, integrating a structural input with the piping input model to capture piping flexibility.

Integrate piping and structural models in Caesar II by inserting a vertical rigid element from node 30 to 31 with restraints to node 3000, noting deflection effects.

Model a surge vessel nozzle in Caesar II, connect a vertical pipe, and calculate nozzle flexibility with WRC 297 to compare forces against allowable limits.

Learn how to insert wind and seismic loads in Caesar II, set wind shear factor, select codes, and configure site-based spectral acceleration and soil data for accurate load cases.

Perform the error check in Caesar II to identify blocking errors and warnings; fix missing alpha values, thickness mismatches, and SIF for a T connection; then proceed to load cases.

Perform a manual model check before finalizing a Caesar II analysis to verify materials, piping codes (B 31.3), diameters, wall thickness, tolerances, and loads, temperatures, pressures, and restraints.

Learn to create and load cases in Caesar II, including recommended, sustained and alternate sustained, expansion and occasional cases, with wind, seismic, hydrostatic, and temperature effects.

Learn how the output processor in Caesar II reveals active vs failed load cases, reviews code compliance, and exports displacement, stresses, and code reports for sustained and hydro test scenarios.

Check pipe system deformations in Caesar II using the output processor, viewing hydro, sustained, and operation cases with motion and volume animation to assess displacement, supports, and temperature-driven expansion.

Check code compliance in Caesar II by visualizing stress in 3D and marking overstress. Compare sustained, expansion, and operation cases, and adjust length to study weight, pressure, and temperature effects.

Learn how to choose vertical support locations to reduce hydro test and expansion stresses in CAESAR II, and implement an expansion loop to absorb longitudinal expansion.

Demonstrate how to design an expansion loop in a pipe system to absorb thermal expansion, using bends and phased segments, with Caesar II analysis to manage lateral supports.

Check forces on supports using Caesar II, export summarized tables in Excel for the structural engineer, and view node-by-node strains, gaps, and friction across restraint and case scenarios.

Learn to check pump nozzle forces with CAESAR II using API 610 equipment analysis, compare results to allowable limits, and use expansion joints to improve safety.

Examine forces on surge vessel nozzles using CAESAR II, applying WRC 100-07297, stress concentration factors, and design parameters to assess safety against allowable stresses.

Distinguish piping from pipelines and explore underground pipeline systems, codes ASME B31.4 vs B31.3, and three main support methods—first blocks, line anchors, and restrained systems—for modeling and analysis.

Learn how Caesar II models underground pipelines by coupling soil weight, depth of cover, and soil strength to elastic and plastic springs, with automatic soil interaction tools.

Learn to model an underground pipeline in Caesar II by defining soil models, cover depth, and springs, then run analysis to diagnose expansion failures and add a thrust block.

Congratulations on completing the basics; discover advanced modelling techniques for surfaces, pump nozzles, and expansion joints in Caesar II, with Autopilot as a complementary tool and ongoing course updates.

Learn to perform flange checks using the ASMI code method in Caesar software, including flange selection, bolt and gasket data, and comparing actual stresses to allowable stresses under various loads.
