A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
Propane, however, has a very high number of BTUs per cubic foot in its outer cone, and so with the right torch (injector style) can make a faster and cleaner cut than acetylene, and is much more useful for heating and bending than acetylene. The maximum neutral flame temperature of propane in oxygen is 2,822 °C (5,112 °F). [13]
An MPS gas is a mixture of two or more of propane, butane ... The most commonly known type of MPS gas is the discontinued MAPP gas. [2] As a fuel gas, it burns ...
A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel and ambient air as its combustion medium. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas (LPG).
A MAPP Torch can "just barely" do copper welding or brass brazing (using proper brazing rod) conveniently (which propane can't and which is much better than soldering). A ts4000 makes plumbing soldering easier than yet cheaper propane torches (ie, it overcomes latent water in pipes easier). See Also: Brazing Arc Welding Oxy-fuel welding Forge ...

Allene exists in equilibrium with methylacetylene (propyne) and the mixture is sometimes called MAPD for methylacetylene-propadiene: . H 3 CC≡CH ⇌ H 2 C=C=CH 2. for which K eq = 0.22 at 270 °C or 0.1 at 5 °C.
