Pipeline Sample Cut-Out Evaluation
During routine construction and modification exercises and in the event of a pipeline failure an evaluation of a cut-out can provide valuable information about the effectiveness of the corrosion control program.
- Providing a procedure for the removal and handling of pipeline cut-outs
- Conducting and documenting a visual evaluation of the pipeline cut-out including;
- Capturing solid samples for evaluation, - Documenting the condition of the pipe sample using photographs;
- When the sample is received,
- After the sample has been cut, and
- After the sample has been cleaned and labeled, - Labeling and measuring all pits and corrosion
- Determining failure mechanism, if possible, from visual examination
- Providing recommendations for preventing future failures of the same type
- Documenting the above for reporting to the regulators
- Managing additional pipe sample evaluation if visual examination is determined to be insufficient
