Abstract
On new construction projects, designers are frequently faced with the choice of whether to use raised face or ring joint flanges for piping systems. Often, decisions are made based on flange types used in the past, without due consideration for the merits of either style. On major piping projects, the decision can have significant and far reaching impacts for the owner of the facility, from a cost, constructability, and operational point of view. The authors of this paper studied several recent projects in North America and Europe and performed a technical comparison of the strengths and weaknesses of each style of flange. The authors also performed a comprehensive estimate of the cost differential between using the different styles of flanges. The provision of both technical and economic data in one paper is intended to provide a resource of data that designers need to make an informed decision about which style of flange to use.

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
