Choose a corrosion-inhibitor route from the signal and metallurgy
A copper result is not a product-selection shortcut. Confirm the sample, locate the source, distinguish open from closed circulation and map every important wetted metal. Then screen a complete program that protects copper alloys without ignoring steel, aluminum, deposits, microbiology, oxidant exposure or equipment conditions.
| System evidence | Corrosion evidence | Document request |
|---|---|---|
| Open/closed boundary, water analysis, pH, temperature, makeup and treatment history | Dissolved/total copper and iron, alloy map, coupons, deposits and inspection | Exact grade identity, current TDS/SDS, specification, COA format and compatibility evidence |
Start with the copper-signal response guide and the broader Cooling Water Treatment application. Review TTA, BTA and the closed-system inhibitor as candidate identity pages only, then request evidence for the actual water and metallurgy.
