A dent can be in combination with a stress concentrator in your pipeline.
In particular, unrestrained dents exposed to pressure cycles form a major threat since they often lead to fatigue cracks. Whatever caused the dent is most likely the cause of any coating removal experienced, so corrosion could be an issue as well.
Traditional geometry inspection tools introduce a problem when it comes to traditional geometry assessment: smoothing. Smoothing and approximation techniques have the ability to alter the geometry data they’re attempting to inspect.
