PNME nozzles are a type of oxy-fuel cutting nozzle used with liquefied petroleum gas (LPG), such as propane. They are a two-piece, nozzle-mix design known for improved safety, as the gases are mixed only at the tip of the nozzle. How PNME nozzles workThe oxy-fuel cutting process uses pure oxygen and a fuel gas to cut steel. PNME nozzles are specifically designed for this process using LPG. 

1. Fuel gas: An outer layer of LPG mixed with oxygen, known as the preheat flame, heats the steel to its kindling temperature (approximately 1,800°F).
2. Cutting oxygen: A high-pressure, pure oxygen stream is then directed to the heated area through a central hole in the nozzle.
3. Chemical reaction: The oxygen stream causes the heated steel to oxidize rapidly, creating molten slag. The force of the oxygen jet blows the slag out of the cut, allowing the torch to continue moving forward.
4. Nozzle-mix design: Unlike other nozzles where gases mix earlier in the torch, the PNME design mixes the oxygen and LPG at the nozzle tip. This separation of gases until the point of ignition is a key safety feature that helps prevent flashbacks and backfires.
