What is an electrofusion coupler?

Electrofusion is another technique for joining Aquatherm pipe (PP-R, RP(RCT))2. It entails using a coupling that is wound with heating element wires embedded in PP-R, which can be slipped over two ends of pipes to be joined.

How do you do electrofusion?

Open one side of the sealed bag containing the electrofusion fitting and slide it on to the pipe. The electrofusion coupler is fitted with a centre stop. Slide the fitting along the pipe until it comes into contact with the centre stop. Mark the insertion depth using an indelible marker pen.

What type of pipe can be joined using electrofusion?

Electrofusion is a method of joining MDPE, HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together.

How do you connect PVC pipe to HDPE pipe?

Threaded Connection: heat-melt one end of the HDPE pipe with an HDPE inner wire directly (or outer wire directly), then glue one end of the PVC pipe to an outer wire directly (or inner wire directly), and then screw the inner and outer wires directly together.

What is the difference between butt fusion and electro fusion?

Pipe structure – whereas in butt fusion welding the pipes to be joined must have the same wall thickness, with electrofusion a difference in wall thickness can be accommodated. Electrofusion can also be used to join certain typesof multiple layer pipes, e.g. nylon lined polyethylene pipe for the conveyance of fuel.

How do you joint a HDPE pipe?

The pipe joining method is a process in which the two ends of the pipes to be heated and welded by using a butt welding machine and the both ends are pushed toward each other by pressure under a certain temperature. Hdpe pipes up to 1200 mm in diameter can be welded by using the welding method.

What fittings are used with HDPE pipe?

HDPE Fittings The most commonly used process to connect HDPE is by heat fusion of pipe butt ends.
