Welding Assessment and Data Trending
In an effort to ensure pipelines continue to operate in a safe condition, various inspections and assessments are completed on a continual basis during their operating lifespan. These assessments include radiographic or ultrasonic examinations, forms of non-destructive examination (NDE), of circumferential girth welds formed between multiple pipe sections. The purpose of this project is to study the data from various NDE reports of circumferential girth welds in order to determine if any trends or commonalities can be developed for evaluating girth weld defects relative to welding specification, defect types, pipe size, vintage and other useful metrics. These trends can be used to provide inferred conditions of welds that have not been directly examined.
