0558011948 - ESAB 4218-19 Propylene Gouging Nozzle

Industrial Grade Propylene Gouging Nozzle

The ESAB 0558011948 is a high-performance gouging tip from the 4218 series, specifically engineered for use with Propylene gas. In the realm of industrial metalworking, the distinction between cutting and gouging is critical; while cutting severs the material, gouging is designed to remove surface metal to create grooves, remove defective welds, or prepare joints for subsequent welding. This specific nozzle, identified as Size #19, is calibrated to handle substantial gas flow rates, enabling the operator to remove significant amounts of material efficiently while maintaining control over the groove depth and width.

Constructed with the durability required for heavy industrial environments, the 4218 series typically features a two-piece design common for alternative fuel tips. This design includes a brass inner member with splines for gas mixing and a heavy-duty copper outer shell. The separation allows for the specific combustion characteristics of Propylene, which requires a different fuel-to-oxygen ratio and mixing turbulence compared to Acetylene. The copper alloy exterior provides excellent thermal conductivity, dissipating the intense heat generated during the gouging process and resisting the adhesion of molten spatter, thereby extending the service life of the consumable.

Technical compatibility is a key factor for procurement. This tip is designed to fit standard Oxweld-style hand torches (such as the C-32, C-66, and C-77 series) that accept 4218 series consumables. The precision machining of the preheat slots ensures a stable, concentric flame that stays lit even when the tip is dragged along the workpiece, a common technique in gouging operations. By utilizing Propylene, facilities can leverage a fuel gas that offers a high heat release in the secondary flame, making it highly effective for heating the broad surface area required during gouging operations.

For MRO (Maintenance, Repair, and Operations) managers, stocking the ESAB 4218-19 ensures that fabrication teams have the specific tooling required for non-acetylene gouging. Using the correct tip for the specific fuel gas is not merely a matter of performance but of safety; it prevents backfires and overheating associated with using mismatched consumables. This nozzle represents a reliable solution for structural steel repair, shipyard maintenance, and heavy equipment refurbishment where weld removal is a daily requirement.
