1 Answer

Answer :

Answer: Whenever a force is applied to any object it applies a reaction force against the deformation by that force. That reaction force per unit area is the measure for the generated stress. There has to be an external force to create stress. In a piping system there are various reasons for the generation of stress like Piping Weight, Internal and External pressure, Change in temperature, Seismic and Wind forces, PSV reaction force etc.
The stresses generated in a piping system are as follows:
1. Axial Stresses
2. Tangential or Hoop stress
3. Longitudinal Stress
4. Radial Stress
5. Expansion Stress
6. Stress due to occasional events like Seismic and Wind effects.
