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.
Further, more of it can be stored in a single place at one time, as the increased compressibility allows for more gas to be put into a tank. MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel.
A report addressing various defects with the Bernzomatic torch products was published in February 2019: United Testing Services Study On February 23, 2012, all fuel cylinders containing MAP/Pro (propylene) and MAPP gas were recalled. Cylinders containing propane fuel were omitted from the recall but under review due to several injuries ...
Oxygen and MAPP gas cylinders with two-stage pressure regulators Schematic diagram of pressure reducing regulator (A) and back-pressure regulator (B). The upper diagrams show the normal state for the valves, which is normally open for pressure reducers and normally closed for back-pressure valves.
The most commonly known type of MPS gas is the discontinued MAPP gas. [2] As a fuel gas, it burns hotter than propylene, propane or natural gas. See also.
