Mapp gas & Mapp pro CAS NO.811-97-2

Mapp gas is 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 is 75mm, height 280mm and gross weight 980g, convenient for holding and carrying.2. The welding temperature can reach 1350°C and the burning temperature can reach 1980°Cunder condition of anaerobic combustion-supporting.3. The burning time can be gotten 2 hours and 40 mins 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.
Packing Details:
1. Disposable steel cylinder (size: 75X280mm; NET: 16 OZ; 12 pcs /CTN, 17004 cyls per 20ft container).
2. Cylinder should be stored in cool, dry and ventilated place.
