Description
Aquatherm 1040090991 3" Electrofusion Coupling
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. An electrical current is applied to the coupling causing heat to be generated in the coils, melting the PPR of the coupling and the pipe together, forming the fusion bond.
The installer manual has several pages dedicated to the proper steps to be taken in making an electrofusion connection. The purpose of this bulletin is to give a little more detail into the preparation, process and expected results of electrofusion couplings.
Electrofusion couplings can be used in some cases where normal fusion equipment cannot be used because of space or height restrictions or when making a final connection in a small space where the rest of the piping is already rigidly in place.
