A '''44-gallon drum''' (known as a '''55-gallon drum''' in America, and increasingly in Australia as a 200-[[litre]] drum) is a cylindrical container ([[Drum (container)|drum]]) with a nominal capacity of 44 [[imperial gallon]]s, 55 [[U.S. gallon]]s, or 208 [[litre]]s. The exact capacity varies with wall thickness and other factors. Standard drums are 572 [[millimetre|mm]] (22.5 inches) in diameter and 850 [[millimetre|mm]] (33.5 inches) high. |

A 44-gallon drum (known as a 55-gallon drum in America, and increasingly in Australia as a 200-litre drum) is a cylindrical container (drum) with a nominal capacity of 44 imperial gallons, 55 U.S. gallons, or 208 litres. The exact capacity varies with wall thickness and other factors. Standard drums are 572 mm (22.5 inches) in diameter and 850 mm (33.5 inches) high.
The drums are typically made of steel with a ribbed outer to improve rigidity and durability. They are often moved by tilting, then rolling along the base, which is designed especially for that purpose. The drums are commonly used for transporting oils and fuels, but can be used for storing various chemicals as well.
Closed-head steel barrels and drums used for shipment of chemicals and petroleum products have a standardised bunghole arrangement, with one 2-inch (50.8 millimeters) NPT and one ¾-inch (19 millimeter) NPT threaded bunghole on opposite sides of the top head. This arrangement is echoed in many plastic drums in the same size.
These drums are also available in open head forms, with a clamp ring or flanges which hold a loose lid (often with a gasket) down on the top.
In the past, hazardous waste was often placed in drums of this size and stored in open fields or buried. Over time, some drums would corrode and leak. As a result, these drums have become iconic of pollution problems, even though they have numerous uses and are ubiquitous in commerce.
Although oil is sometimes shipped in 44 gallon drums, the measurement of oil in barrels is based on 42 (US) gallon wooden barrels of the 1870s.[1]
The steel drums used in calypso music were originally made from these drums. Modern high-quality steel drums, of the kind sold by instrument suppliers, are now made from scratch using a higher quality of steel.
Plastic drums
44-gallon plastic drums are increasingly used. Many do not have ribbing along the side.
Uses include the storage of dry goods and the collection of rain.
