If the seal is intact, it may be okay for perhaps a week or two, but only if the contents have not been exposed to air. If it is past its sell by date, be very careful when opening it, as gas can build up in the keg and cause it to burst out when the seal is broken.
Draught beer is usually unpasteurised in America. It is intended to be kept refrigerated between 2°C (35°F) and 4°C (40°F), and consumed quickly after being "tapped". Above 6°C (44°F), a beer may within two days turn sour and cloudy. Below 6°C (44°F), a keg of draft beer should last 20-30 days before it loses its fresh taste and aroma.
it all depends on the keg, macro breweries don't make beer very well, and it will begin to lose flavor in a month or two, but micro breweries generally only get better with age. But even those should be consumed within 2 years, usually, there are some that just keep getting better, even after a decade.
This is of course only a rule of thumb, there are exceptions.
Depends how quickly it's contents are drunk.
Most kinds of beer will stay carbonated for about 15 hours.
Forever and ever

when its empty !
Keg beer lasts about a month once opened/tapped, but that's assuming that you have a way to maintain pressure in the keg. Usually this is done with a CO2 gas feed that maintains the pressure inside the keg to keep the carbonation in the beer. If you mean the typical 5 liter mini keg you can buy on a store shelf, most have no pressurizing system. Once opened the beer will go flat in a couple of days. There are mini kegerator systems out there that will maintain the pressure, however.
A keg of beer costs around $350 in Pennsylvania.
There are a few different kinds of beer keg taps that are available. Globally, there are six kinds of available options for beer keg taps. These are mostly divided by continent, such as US keg taps and European keg taps.
around 165 in a keg that is almost 16 gallons
Yes. If a keg has a leaks the beer will go flat. It is the pressure of the carbon dioxide (without oxygen) in the keg that keeps the beer from spoiling or going flat.
There are 165 12oz glasses of beer in a 1/2 Barrel (15.5 gallon) Keg.
Keg beer is a term for beer which is served from a pressurised keg. Watney's (UK) started with an experimental pressurised beer Red Barrel which was served in a pressurised Keg rather than the traditional Cask (barrel) in 1936. The use expanded rapidly circa 1960
