# Small Bore Connections

Take NoteThere are some specific cases where the [S-RBI assessment approach](/v414/docs/work-process-degradation-management-implementation-steps) in IMS PEI changes, depending on the Equipment/Component type.  
This section gives **guidance** for Small Bore Connections.

## Define Asset – Step 1

See [Step 1](/v414/docs/step-1-define-the-asset).

Small Bore piping is ≤ 2", often these are Deadlegs. In some cases, when they are used as drains or draw offs, these could be the main pipe. In these cases, the "stand-alone" piping could be the 2" main line and then the bleeders/vents would be the Deadlegs.

## Barrier Verification – Step 12 & Step 13

See [Step 12](/v414/docs/step-12-assign-s-rbi-results-to-inspectioncorrosion-schedules-andor-update-monitoring-plan) and [Step 13](/v414/docs/step-13-barrier-verification-execute-analyze-document).

For small bore piping <2” it is recommended to perform profile RT.
