HPN-10 - Uniweld HPN-10 Heavy Preheat Propane Cutting Tip, Size 10, Victor Style

Heavy-Duty Propane Cutting Performance

The Uniweld HPN-10 is a specialized cutting tip designed for industrial oxy-fuel cutting applications utilizing Propane or Natural Gas. As part of the HPN Series, this tip is engineered with a heavy preheat capacity, making it distinct from standard general-purpose tips. The heavy preheat design incorporates additional preheat splines or a larger preheat orifice area, generating a robust flame capable of rapidly bringing thick, cold, or surface-contaminated steel to kindling temperature. This feature is particularly advantageous in scrap yards, demolition sites, and heavy fabrication environments where materials may be rusty, painted, or coated.

Constructed with a two-piece design, the HPN-10 consists of a brass inner member with splines for gas flow and a copper outer shell that withstands high radiant heat. This separation of materials allows for efficient gas mixing and durability. The tip is sized as a #10, indicating a massive cutting capacity suitable for materials ranging approximately 10 to 12 inches in thickness, depending on gas pressure and torch capability. It is designed to fit standard Victor-style cutting torches and attachments, ensuring broad compatibility with existing equipment fleets.

Operators utilizing alternative fuels often face challenges with preheat times compared to Acetylene; the HPN series directly addresses this by maximizing the thermal transfer of the Propane/Oxygen flame. The tip is suitable for straight cutting, beveling, and piercing operations where high heat input is required to maintain the cut on heavy sections.
