Cathodic protection system for air compression tanks |
| abstract |
"CATHODIC PROTECTION SYSTEM FOR AIR COMPRESSION TANKS". The present invention relates to a corrosion protection device ("CPD") for inhibiting corrosion of an air compressor collection tank and relieving pressure in the tank when excessive condensate is accumulated within the tank. A relief passage extends through the plug, and an anode seals the relief passage near the internal volume of the tank. The tank, plug and anode are all coupled in an electrically conductive relationship, and a galvanic circuit will be formed when condensate is collected near the bottom of the tank. The anode has a lower redox potential than steel and is preferably made of magnesium. The anode loses electrons with less resistance than the steel tank; thus the anode will be consumed through the oxidation process before the steel tank is corroded. Once the anode is consumed so that it no longer seals the relief passage, condensate and air are discharged from the tank through the relief passage. |
