Low Spatter Adhesion Nozzle

One Point! What is a Diverging Nozzle!
– Correctly known as a Divergent Nozzle, it is a type of nozzle used for high-speed cutting with high oxygen cutting pressure.
– Structurally, it differs from a straight nozzle in that the oxygen cutting hole exit widens towards the end.
– This allows for the generation of supersonic oxygen cutting airflow, enabling high-speed cutting.

One Point! What is Concentrated Flame Type!
– The Concentrated Flame Type refers to a nozzle where the preheated gas flow path has a tapered shape.
– Its distinctive feature is that the preheated flame is concentrated at a single point.
– This enables the completion of preheating and piercing operations before cutting starts in a shorter time.
– Due to the concentration of the preheated flame, the setting and adjustment of the nozzle height become more crucial.

Advantages

– By changing the material of the internal nozzle, it suppresses an increase in surface roughness due to heating and reduces spatter adhesion.
– Significantly reduces maintenance frequency, thereby improving nozzle lifespan and operational efficiency.
– Environmental impact is reduced by extending nozzle lifespan and eliminating polyethylene bags for packaging.
– The 3057BBⅡ is designed for high concentration of preheating flame, allowing for quicker completion of piercing and preheating before cutting.
