28 Dia Double Layered Fast Nozzle

The size of the nozzle opening is crucial as it determines the gas flow speed acting on the cutting material, which in turn affects the removal of molten material.

• Double Layered Nozzles: Mainly used for cutting carbon steel with oxygen
• Double layered nozzles, on the other hand, have slow gas flow speeds, making them suitable for high-speed cutting applications. They are often used for cutting carbon steel and generally employ oxygen as the auxiliary gas. The high-speed gas flow enhances the cutting efficiency, but it also causes the cutting surface to turn black due to oxidation.
