Abstract
Abstract Polyamide 11 (PA 11)1 has been used for more than four years in Alberta, Canada as a thermoplastic liner for rehabilitation of rigid carbon steel pipelines that carry corrosive raw sour gas and condensates. Three installations of liners extruded from PA 11 have been completed since November of 1995. These liners were installed using an interference fit. In March of 1998 the first “loose fit”2 liner made from PA 11 was installed in a carbon steel pipe. This paper examines the installation details and service conditions of that installation.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
