A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
The hoses are color-coded for visual identification. The color of the hoses varies between countries. In the United States, the oxygen hose is green and the fuel hose is red. [6] In the UK and other countries, the oxygen hose is blue (black hoses may still be found on old equipment), and the acetylene (fuel) hose is red. [7]
A hose reel is a cylindrical spindle made of either metal, fiberglass, or plastic and is used for storing a hose. The most common styles of hose reels are spring driven (which is self retracting), hand crank, or motor driven. Hose reels are categorized by the diameter and length of the hose they hold, the pressure rating and the
Oxy-fuel combustion also reduces CO 2 release at the glass plant location, although this may be offset by CO 2 production due to electric power generation which is necessary to produce oxygen for the combustion process. Oxy-fuel combustion may also be cost effective in the incineration of low BTU value hazardous waste fuels.
Hose reels that store and prevent kinking of fire hoses or garden hoses; Bobbins that hold yarns or threads for sewing machines and weavers; Retractable tape measures; Fishing reels that store and pull in fishing lines when angling; Film reels that carry film stocks; Many audio recordings of the late 20th century (and some today) use reel-to ...
Combustion of acetylene with oxygen produces a flame of over 3,600 K (3,330 °C; 6,020 °F), releasing 11.8 kJ/g. Oxygen with acetylene is the hottest burning common gas mixture. [32] Acetylene is the third-hottest natural chemical flame after dicyanoacetylene's 5,260 K (4,990 °C; 9,010 °F) and cyanogen at 4,798 K (4,525 °C; 8,177 °F).
Above approximately 4,300 m (14,000 ft) oxygen-rich breathing mixture is required to approximate the oxygen available in the lower atmosphere, [4] while above 12,000 m (40,000 ft) oxygen must be provided under positive pressure. Above 15,000 m (49,000 ft), respiration is not possible because the pressure at which the lungs excrete carbon ...
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
