What is the objective of stress analysis ?

Stress analysis is carried out to ensure that the stresses in piping components in the system are within allowable limits.
To solve dynamic problems developed due to mechanical vibration, fluid hammer, pulsation, relief valves, etc.
Additionally to solve problems associated due to higher or lower operating temperature as:
– Displacement stress range.
– Nozzle loading on connected equipment.
– Pipe displacements.
– Loads & moments on supporting structure.
