Inspection Apparatus
- Direct reading gage or go-no-go type gage is used to locate the area of OD reduction.

- When using the setting rod to verify the calibration of the OD Gage, the deviation indication (pointer) shall be set at “0”.
Procedure

- If the tube diameter is excessively worn or reduced, the OD gage can determine the smallest permissible size by reading the indication pointer.
Reporting
- OD Gage tube inspection shall be recorded in the drill pipe inspection report (CRC-FO-DPIR-XX) for each joint.
- The inspection report shall highlight the OD wear which is OK, Reduced, or Increased with red character.
