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 does not replace professional engineering judgment, operator procedures, or 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. Users should not rely on this tool as a final or authoritative source and should apply professional engineering judgment and applicable procedures.

Dents

Dent

Dent guidance starts with geometric deformation but quickly moves into context: where the dent sits, whether it interacts with other threats, and whether shape alone understates the concern.

Dent at Weld

Dent at weld review focuses on dents located on or near girth or seam welds, where local stiffness changes and weld-related stress effects can drive a different response than a plain dent.

Interaction Issues

Dent with Metal Loss

Dent with metal loss is an interacting condition where a geometric deformation and a wall-loss feature are located in the same local area or close enough that they may influence each other. It is more complex than either condition alone because the dent changes the local stress state while the metal loss reduces wall section and can distort how the defect is classified, sized, and prioritized. Typical sources include outside-force damage with coating disruption, corrosion that develops within or near a dented area, corrosion under an older deformation, and cases where a dent may also include gouging or other mechanical damage.

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.
