    gas cannot be supplied in sufficient quantity to prevent the formation of a hazardous mixture of gas and air, a slug of inert gas must be released into the line before the gas. (b) When a pipeline is being purged of gas by use of air, the air must be released into one end of the line in a moderately rapid and continuous flow. If

  • Oxy-fuel welding and cutting - Wikipedia

    The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound. When used for cutting, the plasma gas flow is increased so that the deeply penetrating plasma jet cuts through the material and molten material is removed in the efflux plasma.

  • Gas-Cutting: Process, Techniques and Advantages | Welding

    Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials. The oxyfuel process is the most widely applied industrial thermal cutting process because it can cut thicknesses from 0.5mm to 250mm, the equipment is low cost and can be used manually or mechanised.

    When cutting stainless steels which have a high chromium content ‘powder cutting’ would be employed. Generally acetylene is used with oxygen to provide the preheat flame but other gases can be used: propane for example or hydrogen which is used for underwater work because of its compressibility.

  • Using alternate fuel gases for cutting and heating

    Plasma cutting really shines in this one – since the plasma is just electrified gas, a plasma cutter will basically cut any material that conducts electricity. Aluminum, steel, stainless, brass, copper, you name it, plasma makes quick work of it. For oxyfuel cutting torches, the answer is a little more complicated.
