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.
These can result from a number of causes including the method of application, the condition of the surface or any pre-treatment. Corrosion is an electro-chemical process which transforms steel influenced by oxygen and water, in iron hydroxyde (rust).Corrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen. A protective coating to the steel required to prevent corrosion.Corrosion of stainless steels can be categorised as one of:orrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen.
