0333-0290 - Victor Size 8 HPP Propylene Cutting Tip

Technical Overview of the Victor 8-HPP Cutting Tip

The Victor 0333-0290 8-HPP Cutting Tip Assembly is a specialized consumable component engineered for industrial oxy-fuel cutting applications utilizing Propylene gas. As part of the High Performance Propylene (HPP) series, this tip is designed to maximize the thermal efficiency and cutting velocity characteristics inherent to propylene fuel. Propylene, known for its high heat release in the secondary flame compared to acetylene, requires specific tip geometry to maintain flame stability and prevent flashback or backfire during operation. The HPP design addresses these requirements, ensuring a stable preheat flame and a concentrated cutting oxygen stream.

This specific model is a Size 8 tip, indicating its classification for heavy-duty material processing. In the Victor nomenclature, a Size 8 tip is typically rated for cutting material thicknesses in the range of 8 to 12 inches (approximately 200mm to 300mm), depending on gas pressure settings and operator technique. This makes the 0333-0290 an essential tool for demolition, heavy fabrication, and scrap processing where deep penetration and substantial kerf clearance are required. The tip features a Type 1 configuration, ensuring compatibility with standard Victor professional torch handles and cutting attachments designed for this seat style.

Constructed from high-grade copper and brass alloys, the 8-HPP tip offers superior thermal conductivity and resistance to heat deformation. The manufacturing process involves precision drilling and swaging to ensure concentricity of the preheat orifices around the central cutting oxygen bore. This precision is critical for maintaining a uniform preheat pattern, which directly influences the quality of the cut face and the ease of initiating the cut on thick plates. Industrial MRO procurement specialists should note that this tip is strictly for use with Propylene and should not be used with Acetylene or other fuel gases due to differences in burning velocities and stoichiometric requirements.

The assembly is designed for durability in harsh industrial environments. The seating surfaces are machined to tight tolerances to ensure a leak-proof seal within the torch head, minimizing the risk of gas mixing within the torch body. Regular inspection of the seating area and the tip face is recommended to maintain optimal performance. Carbon buildup or slag adherence can be managed with standard tip cleaners, provided the correct wire size is used to avoid altering the orifice dimensions.
