Electrofusion fittings

About Rendifield Electrofusion fittings

Electrofusion is a simple and rapid jointing technique for making permanently welded joints. The efficient assembly on-site of pipes, fittings, or prefabricated pipework can be achieved using electrofusion couplers and electrofusion welding equipment. Only fittings with long spigot ends are suitable for electrofusion.

Electrofusion fittings physical properties

Electrofusion welding is a form of resistive implant welding used to join pipes. A fitting with implanted metal coils is placed around two ends of pipes to be joined, and current is passed through the coils. Resistive heating of the coils melts small amounts of the pipe and fitting, and upon solidification, a joint is formed. It is most commonly used to join polyethylene (PE) and polypropylene (PP) pipes. Electrofusion welding is the most common welding technique for joining PE pipes. Because of the consistency of the electrofusion welding process in creating strong joints, it is commonly employed for the construction and repair of gas-carrying pipelines.  The development of the joint strength is affected by several process parameters, and a consistent joining procedure is necessary for the creation of strong joints.

Electrofusion fittings applications

Electrofusion fittings is used in Gas, Water and Waste water applications.
