Mercury Corrosion

The figure shows a perforation in the bottom of a hypochlorite tank caused by liquid mercury lying on the bottom of the tank. The tank had a float valve that contained elemental mercury. The float valve failed mechanically releasing some amount of liquid mercury into the tank. Although the tank was epoxy coated, it nonetheless perforated in a few months time producing the hole in the picture. In the galvanic attack, the mercury deposit was the cathode and the steel was the anode.
