Has anyone ever dealt with cathodic protection in demineralized water with resistivity up to 6.25 million! Can anyone direct me to any reference regarding the corrosivity of this environment. From what I have been told the water is so starved of Fe that it will be aggressive in dissolving...
I've tried Corrpro. They sent me a brochure on Galvalum, which has data up to about 100 C. I know dissolution will be higher, but I'm trying to quantify/approximate how much higher. I know that resistivy goes down with temperature, which may confuse some people into thinking some other...
We are protecting internally coated tanks which will contain an oilfield produced water phase. Resistivities averaging 100 ohm-cm, but vary from 10 ohm-cm to 500ohm-cm. Do you have any experience at these temperatures?
I am looking for any information (e.g. life expectancy, measured potentials) about operating sacrificial anodes (galvalum I, galvalum III, Magnesium H-1 Alloy) at elevated temperatures - up to 200C (392F). Any experience/information/references especially with galvalum III over 100C (212F) would...
Does anyone have any idea where a guy could find an equation or rule for determining the current requirement (i.e. current density) at various service temperature from ambient to over 100 degrees C? Any references or suggestions on where to look would be very helpful. Thanks.
Does anyone know what the anode current density limit is of an anode in a sand environmentn to prevent electro-osmotic drying? If so, can you reference this info to any book or paper? I have looked far and wide.
