Achieve rapid, concentrated heat transfer with the AHT 50 Oxy-Acetylene Heating Nozzle. Specifically engineered for heavy-duty industrial applications, this high-capacity heating tip, often referred to in the trade as a "pepper pot", is designed to deliver a massive thermal output for pre-heating, bending, and straightening thick-section steels. When precision and speed are paramount, the AHT 50 provides the intense flame temperature that only oxy-acetylene can offer.
The AHT (Acetylene Heating Tip) series is a staple in British engineering workshops, known for its robust construction and stable flame characteristics. The AHT 50 model is a high-output nozzle that balances fuel efficiency with high-BTU performance. By utilising a multi-flame orifice design, it distributes heat evenly across the workpiece surface, preventing localised overheating or melting while ensuring deep thermal penetration, essential for maintaining structural integrity in heavy-duty fabrication.
