0333-0261 - Victor Size 00 GPP Series Propylene Cutting Tip

Technical Overview of the Victor 00-GPP Propylene Cutting Tip

The Victor 00-GPP Cutting Tip (SKU: 0333-0261) is a specialized consumable component designed for the precise thermal severing of ferrous metals using Propylene as the fuel gas. Belonging to the GPP (General Purpose Propylene) Series 1 family, this tip is engineered to facilitate both manual and mechanized cutting operations. The tip features a two-piece construction, consisting of a brass outer shell and an inner member with splined gas passages, which is characteristic of tips designed for alternative fuels like propylene to ensure stable flame propagation and optimal mixing.

Technically, the Size 00 designation indicates its calibration for cutting material thicknesses of approximately 1/4 inch (6.4 mm). The gas flow dynamics are specific to this size, requiring a cutting oxygen pressure range of 20-25 psig and a fuel gas pressure of 3-5 psig. At these settings, the tip delivers a cutting speed of 21 to 25 inches per minute (ipm). Consumption rates are engineered for efficiency, with total fuel gas consumption estimated between 5-7 cubic feet per hour (cfh) and total oxygen consumption (preheat plus cutting) ranging significantly based on the phase of operation, with preheat oxygen consumption between 23-108 cfh depending on flame adjustment.

The GPP series utilizes a medium preheat flame pattern, which balances the high heat release rate of propylene with the need to avoid melting the top edge of the cut before the cutting stream is engaged. This makes it suitable for general fabrication, structural steel work, and maintenance repair operations where material conditions may vary. The physical dimensions of the tip (0.8 x 0.7 x 3.2 inches) ensure compatibility with standard Victor Series 1 torch heads and compatible handles. The brass construction ensures thermal conductivity and resistance to spatter adhesion, although regular maintenance of the seating surfaces is required to prevent backfires and leaks.

Operators should note that this tip is strictly for use with Propylene and should not be utilized with Acetylene due to the fundamental differences in gas density, burning velocity, and required air-fuel ratios. The two-piece design allows for the separation of the inner and outer parts, facilitating the cleaning of carbon deposits or slag that may accumulate during heavy use.
