While establishing the rough condition of a dentA local change in pipe surface contour caused by an external force such as mechanical impact or rock impingement but is not accompanied by loss of metal. at the beginning of a dent characterization assessment is important, it becomes critical to get the highest resolution picture of its size, depth, orientation, and the condition of its ability to endure high pressure as these observations move closer to causing real-world actions.

Coincidental and interacting features do not necessarily make them more injurious. For example, a dentA local change in pipe surface contour caused by an external force such as mechanical impact or rock impingement but is not accompanied by loss of metal. that interacts with another dent (or a weldLocalized coalescence of metals produced by heating the materials to the welding temperature, with or without the application of pressure, or by the application…, or a gougeA type of mechanical damage characterized by a groove, cut, or indentation on the surface of the pipe. It typically occurs when a sharp object, such as a rock, …, or a crackA fracture or discontinuity in the wall of a pipeline, where the material is separated or broken, potentially compromising the integrity and safety of the pipel…, etc.) doesn’t necessarily make the dent or its interacting features more threatening to pipeline operations. These interactions can increase their potential injuriousness, but it’s not a foregone conclusion. As a result, these features are analyzed individually and in combination with one another. If an individual or combination assessment yields a result that doesn’t negatively impact dent failureThe inability of a pipeline system to fulfill its intended function or meet the required performance criteria.

Alternatively, if any dent or associated threat does exceed safety standards set forth in API 579, then additional assessments will be required to maximize operational efficiency, safety, and dependability.

When characterizing dents in a pipeline’s construction, geometric differences found in welds are just as critical as those introduced by manufacturing or by third parties. While welds are critical to remediating features of every kind – including dents – their introduction can negatively impact dentA local change in pipe surface contour caused by an external force such as mechanical impact or rock impingement but is not accompanied by loss of metal. failure pressure and fatigueThe process where cracks develop and propagate in a material under cyclic loading or repeated stress over time.

As a result, the same rigor applied to inspecting any change in the makeup of an operation’s pipe walls should be applied to dent-related welds. It’s always best to ensure that a solution accomplishes it goals instead of inadvertently exacerbating the dent threat attempting to be fixed.
