Electrofusion Tee
Gamson manufactures high-performance Electrofusion Equal Tees, designed to create a 90-degree branch connection in HDPE piping systems while maintaining a uniform diameter across all three ports. These fittings are critical for high-integrity networks, such as natural gas and high-pressure water mains, where a fully fused, homogeneous joint is required. By using internal resistive heating technology, the tee creates a permanent molecular bond that is as strong, and often stronger, than the pipe itself.
Key Features
- Integrated Heating Zones: Each of the three ports is equipped with precision-wound resistive heating coils, allowing for consistent and controlled fusion on all sides.
- Smart Barcode Integration: Features a standardized barcode that communicates fusion time, voltage, and cooling requirements to the electrofusion processor, minimizing human error.
- Space-Saving Design: Unlike butt-fusion tees, which require significant space for machine clamps and pipe movement, the electrofusion tee can be installed in tight trenches.
- High Pressure Performance: Available in SDR 11 (PN 16) and SDR 17 (PN 10) configurations, making them suitable for the most demanding utility applications.
- Visual Confirmation: Built-in fusion indicator pins pop up during the heating cycle to provide an immediate visual check that the fitting has reached the necessary expansion pressure.
