Adaptateur de bride à fusion bout à bout HDPE
Stub Flange for Pipeline Connections
Short Description
The HDPE Butt Fusion Flange Adaptor is a purpose-designed fitting that enables PE pipes to be joined with standard flange components in water, gas, and industrial fluid networks. Manufactured from high-grade PE100 resin, the adaptor is engineered to provide a stable, leak-free interface in both above-ground and buried systems.
Intro Product Summary
The smooth fusion end ensures a strong welded connection to the HDPE pipe, while the stub end pairs with a backing ring to form a robust bolted flange joint. This combination makes the adaptor suitable for systems that require frequent disassembly or transitions between different pipeline materials.
This combination of fusion bonding and bolted connection makes the fitting ideal for systems that require both structural reliability and ease of maintenance.
Key Features
- Secure Transition Between PE and Flange Equipment
Provides a solid mechanical connection where HDPE interacts with steel or ductile iron components. - Robust PE100 Construction
Offers excellent toughness, impact resistance, and long-term performance in pressure-rated networks. - Reliable Fusion Compatibility
The fusion face is precision-machined to ensure proper alignment and consistent bead formation. - Maintenance-Friendly Design
The flange side can be unbolted for repairs or equipment replacement without affecting the fused pipe.
Installation Guide
- Align the Pipe and Fitting
Position both parts in the butt fusion equipment ensuring the correct flange orientation. - Face to Create Matching Surfaces
Remove a thin layer to achieve smooth, parallel ends. - Heat Using the Fusion Plate
Follow standard fusion parameters appropriate for the pipe SDR. - Join & Hold Under Pressure
Bring the molten ends together and apply steady pressure until the bead forms. - Allow Natural Cooling
Avoid movement until the joint has fully set. - Attach Backing Ring & Gasket
Insert bolts and tighten evenly in a cross pattern after cooling.
The HDPE Butt Fusion Flange Adaptor is commonly used in:
- Drinking water transportation and distribution
- Gas pipeline systems within permitted pressure classes
- Industrial plants that require mixed-material interfaces
- Pump and valve chambers
- Sewage and recycled water networks
- Mining water delivery or slurry handling lines
- Desalination and treatment plant installations
