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.
Ford is recalling 204,448 Edge and Lincoln MKX crossovers in North America for fuel-tank brackets that can rust and cause gas to leak, the automaker said. The 2007â2008 Edge and MKX have reinforcement brackets that can cause a fuel odor, a fuel leak, or the check-engine light to illuminate if they corrode, Ford said.
