mapp gas(welding & brazing gas)

MAPP gas(Ｍｅｔｈｙｌ　Ａｃｅｔｙｌｅｎｅ　Ｐｒｏｐａｄｉｅｎｅ) is a mixture of various hydrocarbons, principally, methylacetylene and propadiene.

It produces a relatively hot flame (2,976°C) with a high heat release in the primary flame (inner cone) (15,445kJ/m 3 ), less than for acetylene (18,890kJm 3 ) but much higher than for propane (10,433kJm 3 ). The secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas.

The combination of a lower flame temperature, more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.
