MAPP gas is a mixture of various hydrocarbons principally methylacetylene and propadiene.
It produces a relatively hot flame (2976° C) with a high heat release in the primary flame (inner cone) (15, 445kJ/m3) less than for acetylene (18, 890 kJ/m3), but much higher than for propane (10, 433 kJ/m3).
The secondary flame also gives off a high heat release, similar to propane and natural gas The combination era lower flame temperature more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.
1. Its diameter is 75mm height 280mm and gross weight 880g convenient for holding and carrying
2. The welding temperature can be reached 1350° C and the burning temperature can be reached 1980° C under condition of anaerobic combustion-supporting
3. S The burning time can be gotten 2 hours 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 characteristic.
