Inhibitor Developments Managing Oxygen Degradation Corrosion on Carbon Steel Surfaces Immersed in Oxygen Saturated Brine
Bibliographic record
Abstract
Abstract Pre-filmed carbon steel coupons immersed in corrosive oxygen saturated brine were studied at varying levels of shear stress. The laboratory evaluation assessed ‘batch applied’ inhibitor films for providing mitigating benefits against oxygen degradation corrosion. Test protocols were designed to simulate a field pipeline environment in Western Canada challenging ‘continuous injection type’ corrosion control strategies, using Zinc / phosphate chemistry for protecting carbon steel assets from further oxygen corrosion damage. The percent protection afforded by the batch filming inhibitors was compared to the performance of zinc / phosphate continuous injection treatments of non filmed coupons. Two batch inhibitor formulations provided very effective corrosion control against oxygen degradation corrosion on the laboratory tests. The results from this study indicate a ‘batch applied’ corrosion control option is available for consideration in managing corrosion in pipeline environments transferring oxygen rich process brine. The two batch inhibitors performed superior to the Zn / phosphate chemistry in the comparative studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
