Crack-Like Features
Crack-Like Feature
Crack-like feature is a screening label for indications that may represent cracking, crack colonies, seam-related cracking, or another linear threat requiring specialized review and careful data qualification.

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 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 Crack-Like Indicators
Dent with crack-like indicators is the review path for deformations that also show crack-like behavior, crack suspicion, or a local context where cracking cannot be comfortably excluded.
Interaction Issues
Dent with Gouge / Mechanical Damage
Dent with gouge or mechanical damage is the workflow for deformed pipe where the concern includes wall disruption, coating damage, or surface tearing from impact rather than plain geometry alone.
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.
Girth Weld / Fabrication Issues
Girth Weld Anomaly
Girth weld concern helps organize review when an anomaly is on or near a girth weld and the engineer needs to understand whether weld interaction changes significance, data confidence, or next actions.
Girth Weld / Fabrication Issues
Girth Weld Corrosion / Weld-Associated Metal Loss
Girth weld corrosion, or weld-associated metal loss, is the workflow for corrosion that sits at or very near a girth weld, field-joint coating area, heat-affected zone, weld shoulder, or wall-thickness transition where the weld context may change the meaning of the metal loss.
Girth Weld / Fabrication Issues
Girth Weld Cracking
Girth weld cracking is the workflow for crack-like or confirmed cracking associated with a girth weld, heat-affected zone, or weld-adjacent fabrication detail where weld-related failure mechanisms may control the response.
Girth Weld / Fabrication Issues
Lack of Fusion / Incomplete Penetration
Lack of fusion or incomplete penetration review covers fabrication-related weld anomalies where the concern is not ordinary metal loss or cracking alone, but a weld-quality discontinuity that may affect integrity depending on size, location, loading, and service history.
Girth Weld / Fabrication Issues
Seam Weld Anomaly
Seam weld concern is the review path for anomalies that are on or near the longitudinal seam or may reflect seam-related manufacturing susceptibility, cracking, corrosion, or stress interaction. This includes cases where metal loss appears close to the seam and the engineer has to decide whether it is only incidental proximity or whether the seam is actually part of the mechanism.
Manufacturing / Material Anomalies
Selective Seam Weld Corrosion
Selective seam weld corrosion, often shortened to SSWC, is the workflow for corrosion that preferentially follows the longitudinal seam or weld line rather than appearing as ordinary body-pipe metal loss. The practical question is whether the metal loss is truly seam-following and seam-driven, or whether the seam is only nearby and the interaction is incidental.
