When Is Piping Stress Analysis Required?

This study is typically required for piping that experiences high temperature fluctuations, or for long pipe runs such as hot piping to coolers or headers. Cases where equipment is sensitive to external loads may also require a pipe stress analysis.

What is a pipe stress analysis?

Pipe stress analysis is an analytical method to determine how a piping system behaves based on its material, pressure, temperature, fluid, and support. Pipe stress analysis is not an accurate depiction of the piping behavior, but it is a good approximation.

What kind of stresses occur in piping system?

There are five primary piping stresses that can cause failure in a piping system: hoop stress, axial stress, bending stress, torsional stress, and fatigue stress. Hoop stress is the result of pressure being applied to the pipe either internally or externally.
