The document discusses pipe stress analysis, which evaluates the impact of loads, forces, and stresses on piping systems caused by factors such as temperature and pressure. It highlights the importance of performing stress analysis to prevent issues like excessive displacements and equipment failures, and introduces the CAESAR II software as a tool for conducting these analyses. Key properties related to stress analysis and guidelines for acceptable stress limits are also described.

2. WHAT IS STRESSANALYSIS?
A PIPING SYSTEM EXPERINCES LOADS, FORCES AND STRESS DUE TO
VARIOUS FACTORS LIKE:
• TEMPERATURE
• PRESSURE
• WIND
• VIBRATIONS ETC..,
THE STUDY OF PIPING SYSTEM UNDER THESE CRITICAL CONDITIONS
IS PIPE STRESS ANALYSIS.

3. WHAT IS STRESS?
The Resistance developed in the material per unit
area against the applied force is known as STRESS.

4. CAUSES OF STRESS?
• Weight
• Pressure
• Temperature
• Occasional Factors(wind, earthquake)
• Dynamic factor (slug flow, PSV force)
• Differential expansion etc..,

5. WHY DO WE PERFORMSTRESSANALYSIS?
• In order to keep stresses in the pipe within the code allowable.
• In order to keep nozzle loading within code allowable.
• To calculate loads on supports & structures.
• To Determine the pipe displacement.
• To optimize the line routing.
• To solve dynamic problems vibrations, water hammering etc..,

6. WHAT HAPPENIF WE IGNORE STRESS
ANALYSIS?
• Snaking of Lines.
• Failure of Bellow.
• Huge Pipe Displacements.
• Breaking of Supports.
• Flange Leakage.
• Excessive loads on Equipment.
• Serious Fire Hazards.

23. Point’s to Check in the Report
• Sustain and Hydro stresses % must be less than 70%.
• Sustain and Hydro displacement should not exceed 10mm.
• In operating condition Displacement’s in X&Z direction
should not exceed 100mm and In Y-direction should not
exceed 25mm.
