Fusion Flange ≠ Flange Head
Although their names are similar, fusion flanges and fusion flange heads are different components. Fusion flanges are annular connectors with a heating element that seals pipes by melting plastic through electrical current; whereas flange heads specifically refer to the socket portion of the flange. It's like the relationship between a coffee cup and its lid-the flange is a complete assembly, and the flange head is just one of its key components.
Three Key Features of Fusion Flanges
Smart Connection: Built-in resistance wire heating melts the pipe, creating a molecular-level fusion.
Sealing Expert: The annular weld surface eliminates leakage and withstands 15 MPa pressure.
Deformation Adaptability: Maintains connection stability during thermal expansion and contraction, reducing stress cracking.
Application Selection Guide
• Water Supply and Drainage Projects: Corrosion-Resistant PE Flanges are Preferred
• Chemical Pipelines: Requires Steel Reinforcement Members such as Q235
• High-Pressure Systems: Specifications with a wall thickness of 15 mm or greater are more reliable.
• Maintenance: Standard sizes such as 110 mm diameter facilitate quick replacement.
