  • What happens when you burn acetylene with oxygen?

    CUTTING APPLICATIONS, CUTTING PRODUCTION AND SAFETY: [1] Do the weight conversion of the fuel gas considered. When evaluating a specific fuel gas cost, examine how many cubic feet of gas a pound of the fuel that fuel gas delivers. (see fuel data below). [2] Oxygen consumption is an important part of cutting costs.

    The 1/7 rule simply means it is unsafe to flow more than 1/7th of an acetylene cylinder’s total contents. However, in recent years the 1/7 rule has been reduced to a 1/10 rule (see CGA G.1 5.3.3.13). The biggest challenge with acetylene is in heating situations where large flows are needed. The most common heavy duty heating tip sold in the ...

    •A common inside diameter of oxy -fuel gas hose is 1/4 inch. If you calculate the volume of 100 feet of hose with an inside diameter of 1/4 inch, this means, should oxygen enter the fuel gas hose or should fuel gas enter the oxygen hose, a mixed gas explosion with the force potential of 20 sticks of dynamite could occur!

  • Technical Update - Gas Welding - Acetylene vs. Propane

    The fuel gas employed is generally acetylene but propane, LPG (liquefied petroleum gas), natural gas, or methylacetylene propadiene stabilised (MAPP or MPS) may also be employed depending upon availability and cost considerations. The torch employed for oxy-acetylene cutting is shown in Fig. 19.2.

  • Propane vs. Acetylene Cutting and Welding - Rexarc

    Are we well-informed enough to make the best choice of fuel gas for oxyfuel cutting? Oxyfuel cutting is a process used to sever steel via a chemical reaction of oxygen with the base metal at elevated temperature. Once oxygen is mixed with a fuel gas, the temperature rapidly increases to a point high enough to melt and wash away the steel.

    Using an extra oxy fuel torch (pre heat torch) can be installed perpendicular to the material and running in front of the cutting torch can improve the cutting speed significantly (100% at 70 degrees cutting angle and 50% at 45 degrees cutting angle). To avoid unnecessary gas consumption this pre-heater should only be activated for

  • Which is better for cutting propane or acetylene?

    2.1 Introduction. Oxy-acetylene gas welding is one of the oldest methods of welding and, for many years, was the most widely used welding technique. Its use is a lot less common today. Nevertheless, it is a versatile method, using simple and relatively cheap equipment. It is suitable for repair and construction work, for welding pipes/tubes and ...

    Feb 27, 2017 · The oxyfuel cutting process is nothing more than rapid oxidation—also known as burning. Of course, cost is always a concern for fabricators, and the cost of fuel gas—whether acetylene, propylene, or propane—typically represents 20 to 25 percent of the total cutting cost. But even more than cost, safety is the utmost concern.
