The effect of long-term stagnation on copper corrosion by-product release and corrosion rates was studied in pipe-rigs according to the German standard DIN 50931, Part 1. The analysis of the water phase was supplemented by surface analysis of corrosion scales. Copper concentration during stagnation did not follow a solubility process. The characteristic(More)

Based on a literature study and on pipe-rig studies a mechanism is proposed which subdivides general corrosion of copper into three subprocesses: oxidation, scale formation and dissolution. The subprocesses are further characterized and a mathematical model is built on the identified kinetic rate laws. Finally, conclusions for optimising corrosion control(More)
