G03 machine propane cutting nozzle

The G03 propane cutting nozzle is the core component of propane gas cutting equipment, designed specifically for mechanical automation cutting scenarios. Its detailed introduction is as follows:

Definition and Function

The G03 propane cutting nozzle belongs to the isobaric cutting nozzle, suitable for mechanical cutting equipment using propane as gas. Through detailed internal gas path design, propane gas is mixed with oxygen in proportion and sprayed out to form a high-temperature cutting flame, achieving effective cutting of metal materials. It is a key accessory to protect cutting accuracy, speed, and quality.

Material and Craftsmanship

Main material:

The mouth part is made of excellent purple copper, which has good thermal conductivity and high temperature resistance (based on actual reports), and can maintain structural stability in the high-temperature cutting environment, avoiding deformation caused by overheating and affecting the cutting effect.

The golden component at the connection point is made of brass, which has good mechanical strength and sealing properties. It is confirmed that the connection with the cutting torch is firm to prevent gas leakage.

Processing technology: Adopting precision suitable CNC machining to protect the dimensional accuracy and concentricity of the inner hole and spray hole. The surface is treated with chrome plating to enhance performance and corrosiveness, while improving the smoothness and practicality of the appearance.

structural design

Equal pressure structure: Gas and oxygen are mixed at equal pressure inside the cutting nozzle, ensuring stable flame combustion and reducing the risk of backfire during the cutting process, resulting in high safety.

Multi nozzle design: The cutting nozzle head is equipped with multiple evenly distributed nozzles (as shown in the circular nozzle structure in the figure), which can fully mix gas and oxygen, form a cutting flame with concentrated energy and uniform temperature, and improve cutting efficiency and incision quality.

Cone shaped mouth body: The mouth body is designed in a conical shape, with the front end gradually narrowing to facilitate precise alignment with the cutting position and reduce the adhesion of slag during the cutting process.

performance advantage

Good cutting efficiency: The equal pressure structure and multi nozzle design concentrate the flame energy, making it suitable for melting metal at a suitable speed. It is suitable for cutting medium and thick plates (usually carbon steel with a thickness of 6-100mm), and the cutting speed is significantly improved compared to ordinary cutting nozzles.

Excellent cutting quality: The flame temperature is uniform and stable, and the cut is smooth and polished with less slag residue, reducing subsequent polishing processes. Especially in mechanical automation cutting, it can protect high dimensional accuracy.

Strong practicality: The combination of purple copper material and chrome plating process makes it have good high temperature resistance (based on actual reports) and wear resistance, long service life, and reduces the frequency and cost of component replacement.

Wide adaptability: Designed specifically for propane gas, it can be adapted to various types of propane cutting equipment for machinery, such as CNC cutting machines, semi-automatic cutting machines, etc., to meet the cutting needs of different scenarios.

Specifications and Applications

Specification and Model: Depending on the cutting thickness, there are multiple specifications to choose from (such as G03-3 #, G03-5 #, G03-10 #, etc.), and the larger the model number, the thicker the corresponding cutting thickness.

Application scenarios: Widely used in industries such as steel structure manufacturing, shipbuilding, mechanical processing, and automotive parts production for automated cutting of medium and thick plates, it is an important protection for achieving effective and meticulous metal cutting.
