ISOMETRIC DRAWING

PREFACE

• Piping Stress analysis is a term applied to calculations, which address the static and dynamic loading resulting from the effects of gravity, temperature changes, internal and external pressures, changes in fluid flow rate and seismic activity.

• Codes and standards establish the minimum requirements of stress analysis.

APPLICATION

• Safety of piping and piping components.

• Safety of connected equipment and supporting structure.

• Piping deflections are within the limits.

STATIC ANALYSIS

• Comprehensive Load Case• Interactive Error Checking• Extensive Spring Hanger • Wind Load Calculations• Nozzle Flexibilities and Stresses• Equipment Load Checks• Flange Leakage and Stress Checks• Fatigue and Cumulative Usage Analysis• Wave and Current Load Analysis

DYNAMIC ANALYSIS

• Mode Shape and Natural Frequency Calculations

• Harmonic Displacement and Force Analysis

• Shock Spectrum Analysis and Independent

• Support Motion• Force Spectrum Analysis• Modal Time History Analysis• Animation of Dynamic Response• Missing Mass/Force Corrections• Static/Dynamic Load Combinations• Relief Valve Load Synthesis• Data Interfaces

CONCLUSION OF C+ IND CASE STUDY:1

• As per Input support location is not identified so, the deflection increases and henceforth allowable stress on the pipe increases subjected to temperature and pressure

• Report based on the input as follows • Analyzed reports shall be submitted in the required format of the

customer.

• Case study 2 comprises the same input as case study 1 excluding the pipe supports and hangers.

• Restraints input (at specific & maximum displacement node point from case study 1) is as follows.

CONCLUSION OF C+ IND CASE STUDY:2

• The Analysis of case study 2 is within allowable stress condition since, the absorption of the loads are carried by supports and hangers.

• The supports and hangers acts as guides to the pipe routing and also deflects the loads acting on the pipe.
