0333-0332 - Victor Type HPN Size 12 Heavy Preheat Propane/Natural Gas Cutting Tip

Technical Overview of the Victor 12-HPN Cutting Tip

The Victor 0333-0332 12-HPN Cutting Tip is a high-performance industrial component engineered for the most demanding cutting operations. Part of the HPN series, this tip is specifically calibrated for use with Propane and Natural Gas, offering a cost-effective alternative to acetylene for heavy-volume applications. The 'HPN' designation indicates a Heavy Preheat design, which utilizes a robust flame structure to rapidly raise the temperature of the base metal. This is particularly critical when working with materials that have high thermal mass or surface contaminants such as rust, scale, or heavy paint.

Technically, the Size 12 orifice is a significant differentiator, enabling a cutting capacity of up to 18 inches (457mm). This places the 12-HPN in the extreme heavy-duty category, suitable for slab cutting, ladle splitting, and massive structural demolition. The tip operates with a cutting oxygen pressure range of 45 to 55 psig and a fuel pressure range of 10 to 16 psig. The preheat oxygen flow is substantial, rated at 60/290 SCFH, ensuring that the cut remains stable even at the slow travel speeds of 2 to 3 inches per minute required for such thick sections.

Constructed from high-quality brass, the one-piece design ensures thermal conductivity and durability. The tip geometry is optimized to maintain a coherent oxygen jet over long distances, which is essential for maintaining cut quality through 18 inches of steel. By leveraging alternative fuels like propane, facilities can achieve significant operational savings without compromising on the thermal energy required for heavy preheat tasks like beveling and scrap processing.
