65Z14 - Oxweld 1515-20 Propane/Natural Gas Heating Nozzle

Heavy-Duty Heating with the Oxweld 1515-20 Nozzle

The Oxweld 1515-20 Heating Nozzle (SKU: 65Z14) is a premium industrial component designed for heavy-duty heating applications utilizing alternate fuels. Engineered by ESAB under the renowned Oxweld brand, this multi-flame nozzle is specifically calibrated for use with Propane and Natural Gas. By leveraging these economical fuel sources, the 1515 series allows fabrication shops and industrial facilities to achieve high BTU output without the higher cost associated with Acetylene, making it an essential tool for large-scale preheating and metal manipulation tasks.

The Size 20 configuration indicates a large orifice capacity, capable of delivering a massive volume of heat to the workpiece rapidly. This makes the nozzle particularly effective for preheating thick plates prior to welding, straightening structural steel members, bending pipe, and shrinking heavy components. The multi-flame head design ensures that heat is distributed evenly over a wide surface area, preventing localized hot spots and ensuring uniform thermal soak. This is critical in metallurgy to maintain material properties during thermal cycling.

Constructed from high-grade copper, the 1515-20 nozzle is built to withstand the intense reflected heat generated during prolonged heating cycles. Its robust design features optimized internal flow channels that promote stable flame characteristics and resist backfire, enhancing operator safety. The nozzle is compatible with standard heavy-duty Oxweld torch handles and attachments, such as the W-48, C-32, and C-66, allowing for seamless integration into existing oxy-fuel setups. Whether used in shipyards, rail yards, or heavy equipment manufacturing, this nozzle delivers the reliability and performance professionals demand.

Technical Specifications

The 1515 series is distinct from acetylene nozzles (such as the 1502 series) due to the recess and porting required for alternate fuels. Operators must ensure they are using the correct mixer or injector compatible with propane/natural gas when installing this tip. The 65Z14 part number represents the specific Size 20 variant, offering one of the highest heat outputs in the range. Proper gas pressure settings should be maintained according to the manufacturer's charts to ensure optimal flame stability and efficiency.
