MAPP gas is a mixture of various hydrocarbons, principally,
methylacetylene and propadiene. It produces a relatively hot flame
(2,976C) 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
MAPP gas physical and chemical property:
1. Its diameter is 75mm, height 267 mm and gross weight 880g,
convenient for holding and carrying.
2. The welding temperature can be reached 1350 and the burning temperature can be reached 1980 under condition of anaerobic combustion-supporting.
3. The burning time can be gottten 2hours and 40mins continuance
under normal working circumstance.
4. It guarantees you good jointing and shorter working time because
of its scientific blend proportion and favorable flame
