Pipe Stress Analyisis

'IOMJ?P>ODJI • During operation, pipeline always have variation loading that create stress • To ensure the pipeline safe along the design life, stress analysis need to be conducted • Pipe stress analysis schematic will be: • Code is adopted from failure theory. Code development consists of main aspects like flexibility effect, safety factor, welding effect, etc in failure theory

•

Stress: Stress of a material is the internal resistance per unit area to the deformation caused by applied load.

•

Strain: Strain is unit deformation under applied load.
