MAPP gas is a stabilized mixture of various hydrocarbons, principally methyl acetylene and propadiene. It produces a flame temperature (2,976°C) second only to acetylene when burned in oxygen. It has a high heat release in its primary flame (inner cone) (15,445kJ/m3), slightly lower than that of acetylene (18,890kJ/m3) and much higher than that of propane (10,433kJ/m3). Its secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas. MAPP gas combines the qualities of an acetylene flame with a more even heat distribution. It burns hotter than propane and natural gas, and it can burn continuously for 3 hours under normal working condition. The welding temperature can reach 1350°C and the combustion temperature can reach 1300°C under anaerobic conditions.
