Mapp Gas / Mixture Of Various Hydrocarbons Mapp Gas For Welding 

 

 

Quick Detail:

 

MAPP Gas is colorless in both liquid and gas form. The name comes from the original chemical composition: methylacetylene-propadiene propane.

 

 

Specifications:

 

Mapp gas has a pronounced acetylene-like or fishy odor at concentrations above 100 ppm, due to the addition of substituted amines as a polymerization inhibitor. Low molecular weight alkynes have strong odors. MAPP gas is toxic if inhaled at high concentrations.

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.

 

 

Application:

 

MAPP gas is also widely used as a generic name for UN 1060 stabilised methylacetylene-propadiene (unstabilised methylacetylene-propadiene is known as MAPD). MAPP gas is widely regarded as a safer and easier-to-use substitute for acetylene.

 

 

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.
