Cutting Nozzle (3 Seats Nozzle) ｜ High Cutting Stability for Wide-Range Oxy-Fuel Cutting
Key Takeaways
• The 3 Seats Nozzle is designed to enhance gas flow stability, ideal for thick plate cutting and heavy industrial applications
• Precisely controls the direction of cutting oxygen, reducing flame fluctuation
• Compatible with multiple fuel gases such as Acetylene, LPG, Ethylene, LNG / CNG
• Available in multiple models to match plate thickness ranges, nozzle sizes, and compatible cutting torches
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
In Oxy-Fuel cutting processes, thick plate cutting and continuous cutting operations require significantly higher flame stability than general cutting work. The 3 Seats Nozzle was developed to control multi-layer gas flow, reduce flame fluctuation, and maintain consistent cut quality even under heavy-duty and long-duration cutting conditions.
When cutting thick steel plates, operators often encounter rough cut surfaces, unstable flames, or slag buildup even when gas pressure is properly set. These issues are commonly caused by nozzles that cannot withstand high cutting loads. The use of a 3 Seats Nozzle helps maintain flame shape, enables continuous cutting, and preserves cut quality throughout the operation.
The 3 Seats Nozzle features a structure that systematically separates gas flow into multiple layers, resulting in more uniform gas distribution. Cutting oxygen is injected with a straight, focused direction without dispersion, while internal turbulence within the nozzle is effectively reduced. With these characteristics, it is particularly well suited for thick plate cutting, long continuous cutting, and heavy industrial applications that demand high process stability.
