If you dispense your beer with a party pump, which uses air instead of CO2 to drive the beer, you can only expect your beer to remain fresh for 8-12 hours. If you keep your kegs warm, and drive them with CO2 through a jockey box or other faucet, they will most likely last a couple of months.
Rust by definition is the result of the oxidation of metal. One engine manufacturer refers to the process of corrosion in aircraft engines as galvanic corrosion which is a type of corrosion caused by dissimilar metals being in close proximity of each other. In this process an electrolyte such as water also needs to be present. Almost all metals will oxidize or corrode.
A major contributor to the forming of oxides is the fact that all base metals and alloys have different electri-cal potential.And that brings us to the first of the two major causes of corrosion: electron flow, or galvanic action, caused by the flow of electrons between the differing metals in the alloy.he owner re-layed to me his mechanicâs insistence that the airplane was corrosion free. I unzipped the spanwise headliner access, pulled down the original fiberglass in-sulation and found a mess. The picture says it all. On a scale of 1 to 5, I would rate this level of corrosion a healthy 4+.
