Electrofusion Coupler
electrofusion coupler is a high-density polyethylene (HDPE) fitting used to join PE pipes by passing an electric current through embedded heating coils. These couplers create a strong, homogeneous, and leak-free weld for gas, water, and industrial applications. They are efficient, durable, and ideal for tight spaces where butt welding is not possible.
Key Features and Specifications
- Material: Made from PE100 or PE100RC virgin resin.
- Mechanism: Embedded wire coils melt the pipe and coupler interface, creating a secure bond.
- Operating Voltage: Typically ranges from 39.5V to 48V.
- Identification: Features a barcode for automated welding parameters.
- Pressure Rating: Suitable for high-pressure applications (e.g., up to PN25 bar).
nstallation Process
- Preparation: Cut the pipe square, clean thoroughly with degreasing wipes, and scrape the surface to remove the oxidized layer.
- Marking: Mark the insertion depth to ensure correct positioning.
- Assembly: Insert the pipes into the coupler, using re-rounding tools if necessary.
- Welding: Use an electrofusion processor to scan the barcode and apply the necessary current.
- Cooling: Allow the joint to cool completely before removing clamps or pressurizing, as specified by the manufacturer.
Advantages
- High Strength: Produces a reliable, fully welded, leak-free joint.
- Efficiency: Reduces assembly time and, in some cases, can be used for repairs without needing to expose the entire pipe length.
- Versatility: Suitable for various applications, including mining, irrigation, and gas distribution.
