HDPE Butt Fusion Flange Bushing for Siphonic Drainage

Key Features

• Flange Adaptation: One end is butt fusion compatible, the other features a thickened stop ring for use with metal flanges.
• Butt Fusion Joint: Fuses homogeneously with HDPE pipe, creating a permanent leak-proof connection.
• Anchoring Function: The stop ring fits between the flange and pipe, preventing axial movement due to thermal changes or water hammer.
• High Strength: Injection molded with reinforced stop ring base for high pressure capacity.

Production Technology

• Injection molded from HDPE; stop ring and stub body are integrally formed

Critical Process Parameters

• Fit tolerance between stop ring outer diameter and flange inner diameter
• Flatness and perpendicularity of butt fusion face

Typical Applications

• Transition connection between siphonic drainage pipes and metal flanged valves or equipment
• Anchor points where pipes pass through floors or walls
• Pipe reinforcement at fixed supports in long straight runs
• Nodes requiring prevention of axial pipe movement

Application Scenarios

• Flanged connection at the base of siphonic stacks transitioning to horizontal discharge
• Transition between HDPE pipe and pump flange in pump rooms
• Anchoring at points where pipes cross structural expansion joints
