SAF
Equal to the local peak alternating stress in a component (including welds) divided by the nominal alternating stress in the pipe wall at the location of the component.

SAF
Equal to the local peak alternating stress in a component (including welds) divided by the nominal alternating stress in a defined reference section somewhere in the system (e.g. through wall section of the wellhead above or below the locking profile).
- NOTE: This factor is used to account for the increase in the stresses caused by geometric stress amplifiers which occur in connector components.
