Mapp gasis a mixture of various hydrocarbons, principally, methylacetylene , propadiene and Propane(MAPP). 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.
Welding gas physical and chemical property:
1. Its diameter is75mm, height267mmand gross weight980g, convenient for holding and carrying. 2. The welding temperature can reach1350°C and the burning temperature can reach 1980°C under condition of anaerobic combustion-supporting. 3. The burning time can be gotten2 hoursand40 minscontinuance under normal working circumstance. 4. It guarantees you good jointing and shorter working time because of its scientific blend proportion and favorable flame characteristic.
