Pipeline Integrity Guidance Tool

A structured reference for evaluating pipeline defects and integrity conditions.

This tool provides structured guidance for evaluating pipeline defects and integrity conditions. It is designed to support engineering thinking, data collection, and early-stage assessment.

It is intended to support, not replace, professional engineering judgment, operator procedures, or applicable regulatory requirements.

Beta notice: This tool is an active development (beta) version. Content, structure, and guidance may change over time and may contain errors or incomplete information. It should be used as informational and decision-support context alongside professional engineering judgment, operator procedures, and applicable requirements.

Interaction Issues

External Damage: Bullet Strikes and Equipment Impacts

External mechanical damage from bullet strikes, equipment impacts, dropped objects, vehicle strikes, or other third-party contact can introduce dents, gouges, coating damage, localized wall loss, and stress concentration in the same local area. These conditions are not always obvious from ILI alone, so field confirmation often becomes important when the mechanism, severity, or interaction is uncertain.

Interaction Issues

Gouge

A gouge is localized mechanical damage where metal has been displaced, torn, or removed from the pipe surface. It may occur with a dent, but it can also exist without obvious gross deformation and still be important because the local notch effect, wall disturbance, and potential crack initiation can govern the integrity concern.
