Keg are a capacity from steel which is used for storage and transportation of kvass, beer and other drinks.
Keg it is the best capacity for long-term storage of drinks such as beer and kvass.
Keg well keep taste of drink, without passing bacteria and a sunlight that increases period of storage of a product.it is a metal beer barrel with a volume of 20, 25, 30 or 50 liters. Keg it is made from stainless steel which alloy adapts to requirements of the spilled drink. Keg use for transportation and storage of beer and other drinks and considerably prolongs period of storage of beer.
By the form and designs keg — a thing quite simple. The internal steel vessel consists of two semi-flasks which are strongly connected by a welded seam. From above and from below steel rings ("galleries") which hold keg in vertical position are welded, allow to stack it and protect from mechanical damages. In the top part on the center of a keg there is a fitting — the steel, reaching to the bottom tube with the valve which is hermetically connecting to capacity. Through a fitting beer is filled in in a keg, through it extorted. By means of an intaking head from a cylinder gas is supplied, under its pressure beer rises and comes to the crane.
Service life of keg — from 15 to 20 years. It depends on quality of production and service conditions. Today in Russia standard keg are used: DIN and Euro. At the identical capacity of a kega of the DIN standard higher and already, than Euro. Evrokeg happen various basic diameters corresponding to different types of pallets for warehousing of a container. Besides, there are two more specific types of keg: "plus-keg" and "financial-keg". The first — the "dressed" keg, i.e. vplavlenny in the polyurethane cover providing continuous protection of a steel cylinder against blows and pushes. The cover considerably increases service life of a keg. On "financial-keg" with the same purpose feedwells from the pressed polyethylene are got. Each such type has a subtype, also standard size.
