Briton MAPP Gas General Information
What is MAPP Gas?
A safer and easier-to-use substitute for acetylene.
Work faster and more efficiently with a higher burn temperature than standard propane.
MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding due to its high flame temperature of 2,925 °C (5,300 °F) in oxygen.
MAPP gas is also used in combustion with air for brazing and soldering, where it has a slight advantage over competing propane fuel due to its higher combustion temperature of 2,020 °C (3,670 °F) in air
Firstly: Propane cannot be used for Gas Welding. When acetylene burns in oxygen, it creates a reducing zone that cleans the steel surface. Propane do not have a reducing zone like acetylene and can hence not be used for Gas Welding.
Propane can like acetylene be used for Brazing. For capillary brazing (silver brazing) equal result. For Braze “welding” (thick flowing brazing alloys) acetylene will be an advantage
Propane can like acetylene be used for cutting. If you cut with acetylene, you normally put the tip of the inner flame cone on the metal (1mm from the plate surface). If you do the same with propane, you will be waiting for a long time. If you raise the torch so that the outer flame cone is used the preheat process is started faster. Propane releases only a small proportion of heat in the inner flame cone (less than 10%), so most of the heat in the flame is located in the outer cone. Acetylene releases almost 40% of its heat in the inner flame cone.
