Abstract
Solidification of water in closed piping systems is a common phenomenon in both the industrial and residential sectors. In some cases, the resulting damage may be both costly and dangerous and thus warrants attention. Therefore, further study of the cooling and freezing behavior of stagnant water within closed pipes seems to be necessary. In this regard, several experiments were performed to investigate the freezing behavior of water in pipes. The inelastic deformation, work hardening, and fracture of the pipes that were caused by volume expansion due to the freezing of the water were also studied. Two conventional steel pipe materials, namely ASTM A333-6 and ASTM A106-B, were used in the freezing tests. The fracture surfaces of the pipes were analyzed by using both macroscale and microscale images of the surfaces. Fractography analysis of the fractured regions was also performed by using a scanning electron microscope. It was found that the damage caused during freezing to the A106-B pipe was considerably more than that in the A333-6 pipe. The results confirm that A333-6 should be used instead of A106-B in pressure equipment, such as pipes, that are exposed to low temperatures.

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
