20234 - ESAB Oxweld Style Heating Nozzle 1500 FG

Industrial Grade Heating Performance

The ESAB 20234 Heating Nozzle (#70 0 FG 1500) is a specialized oxy-fuel component designed for heavy industrial heating applications. Engineered to operate with alternative fuel gases—such as propane, natural gas, and propylene—this nozzle offers a safer and more economical alternative to acetylene for large-scale thermal operations. The 'FG' designation explicitly indicates its optimization for these slower-burning, high-BTU gases, ensuring flame stability and preventing flashback conditions often associated with using incorrect tips.

This multi-flame heating head, often referred to in the industry as a 'rosebud,' features a robust construction capable of withstanding the intense reflected heat generated during prolonged use. The #70 designation and 1500 series sizing suggest a high-capacity flow rate, making it suitable for heating large surface areas quickly. It is an essential tool for fabrication shops requiring efficient preheating of thick plate prior to welding, ensuring proper interpass temperatures are maintained to prevent cracking and metallurgical defects.

The nozzle's design incorporates multiple ports to distribute heat evenly across the workpiece, avoiding localized hot spots and ensuring a soaking heat that penetrates deep into the material. This is particularly critical for thermal straightening of structural steel, bending large pipes, or hot-forming metal parts. By utilizing fuel gases, operators can achieve the necessary BTUs for these massive heat sinks without the high cost or cylinder constraints of acetylene.

Compatibility is key with the ESAB 20234. It is designed to fit standard heavy-duty torch handles compatible with ESAB/Oxweld style equipment. The precision-drilled ports ensure a consistent flame shape and velocity, providing the operator with excellent control over the heat input. Whether used in shipyards, heavy equipment repair, or structural steel fabrication, this heating nozzle represents a standard of reliability and performance expected from ESAB's gas equipment line.
