0558005047 - ESAB 1567-8 Propane/MAPP Heating Nozzle

High-Efficiency Alternate Fuel Heating

The ESAB 1567-8 Multi-Flame Heating Nozzle is a specialized oxy-fuel component designed for high-efficiency heating applications utilizing alternate fuel gases such as MAPP, Propane, and Natural Gas. Engineered within the renowned Oxweld product lineage, this nozzle features a multi-flame orifice configuration that optimizes the combustion of slower-burning fuel gases. Unlike acetylene, alternate fuels require a specific tip geometry to stabilize the flame and maximize the BTU transfer to the workpiece. The 1567 series addresses this by employing a recessed tip design or specific porting that anchors the flame at high flow rates, preventing blow-off and ensuring consistent heat input.

This size 8 nozzle provides a substantial heat output, making it suitable for medium-to-heavy duty industrial applications including preheating prior to welding, post-weld heat treatment, flame straightening of structural members, and hot bending of pipe or plate. The construction utilizes high-conductivity copper for the tip end to dissipate reflected heat effectively, reducing the risk of flashback and extending consumable life. The rear assembly is precision-machined to mate securely with compatible mixers and torch handles, ensuring a leak-free gas seal and optimal mixing ratios.

Technical professionals will appreciate the 1567-8's ability to leverage the high total heat content of propane and MAPP gas. While the primary cone temperature is lower than acetylene, the secondary flame envelope provides a massive amount of heat energy (BTUs), which is ideal for "soaking" heat into large thermal masses. This makes the 1567-8 an economic choice for shops looking to reduce acetylene consumption for non-welding heating tasks. Proper mixer selection is critical to ensure the correct oxygen-to-fuel ratio is delivered to the head for complete combustion and maximum thermal efficiency.
