Abstract

fetched live from OpenAlex

The objective of this project is to study the impact of testing voltages for holiday detection on the long term integrity of FBE coatings. It is designed to determine the optimum testing voltage for locating holidays on FBE coated pipelines without causing damage to the coating, and also to establish an optimal grounding procedure for holiday detection. To achieve the set goals of this project, the work plan was designed to include both laboratory and field testing components. The coupons used for laboratory evaluation in this study were made from Grade X70, 36� OD X 0.465� WT pipeline with a 16 mil single layer FBE coating. Test voltages ranged from 2.8 kV to 7.1 kV in an attempt to establish an upper cut-off voltage limit above which the coating will be damaged. Temperatures of 20 �C and 40 �C, and relative humidity of 25%, 55% and 95% were tested. Temperatures of 0 �C and -20 �C were also tested to simulate cold climatic conditions. One pinhole holiday size of 790 �m (0.031�) diameter was selected to be milled on all the prepared coupons.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
