Product Features & Applications

This is a propane cutting nozzle, a core consumable for manual and machine-operated flame cutting machines, purpose-built for propane (LPG) flame cutting. Made of high-purity brass/copper, it offers high temperature resistance and anti-burn performance. Its graded channel structure enables precise mixing of fuel gas and oxygen to form a stable high-temperature flame, used for efficient cutting of carbon steel, steel plates, and other materials. It is a widely used consumable in engineering, steel structure, and sheet metal processing.

1. Basic Product Information

This G03 type propane cutting nozzle is compatible with both manual and machine-operated flame cutting torches. Precisely machined from high-purity brass with smooth, burr-free channels, it fits standard propane flame torches and CNC flame cutting machines. Packaged in boxes, common sizes are 1#/2#/3#, each corresponding to different cutting thicknesses, making it a dedicated consumable for flame cutting of carbon steel and low-alloy steel.

2. Performance and Advantages

  • Stable Flame: The graded channel design ensures thorough mixing of propane and oxygen, producing a clear, evenly heated flame. This results in high perpendicularity of the cut surface with minimal slag, reducing subsequent grinding work.
  • High Temperature Resistance & Durability: Pure copper material offers excellent thermal conductivity for rapid heat dissipation, resisting high-temperature erosion and deformation for a long service life.
  • Anti-Flashback Design: The optimized gas channel structure reduces flashback risks, enhancing operational safety during cutting.
  • Wide Compatibility: Standard interface design fits most manual cutting torches and CNC flame cutting machines, requiring no additional modification for installation.

3. Size Selection and Operating Recommendations

  • Size Selection:
    • 1# Nozzle: For 5-10mm thin plates, offering a concentrated flame for fast cutting speeds.
    • 2# Nozzle: For 10-20mm medium-thick plates, balancing efficiency and stability.
    • 3# Nozzle: For 20-30mm thick plates, delivering high flame power and strong penetration.
  • Operating Recommendations:
    1. Inspect the nozzle channels for blockages from oil or debris before installation to ensure stable flame formation.
    2. Adjust propane and oxygen pressures according to the cutting thickness; excessive pressure can cause nozzle burn-out, while insufficient pressure leads to unstable flames.
    3. Maintain a consistent distance between the nozzle and the workpiece during cutting to avoid contamination or deformation from contact.
    4. Regularly clean oxide slag from the nozzle to prevent channel blockages that could cause flashbacks.

4. Application Scenarios

Widely used in steel structure factories, on-site engineering projects, and sheet metal processing workshops, it performs straight cuts, bevel cuts, and blanking operations on carbon steel, low-alloy steel, and ordinary steel plates. Compared to acetylene cutting nozzles, propane nozzles offer lower cost and higher safety, making them the mainstream choice for flame cutting.
