"Resistance of Duplex SS to alkaline sequestrants"
Question:
"Does anyone have any information on whether any detrimental effects may be expected on Duplex types in general when descaling using potassium EDTA descalers? Typical situations involve pH 10-12, temperatures 60-90 deg.C, total ionic active concentrations up to 25% and contact times 6 to 24 hours."
Answer:
I would not anticipate any problems with your proposed descaling procedure.
