What is Butt Fusion? The Joining of two ends of HDPE pipe or fittings

Pipe Ends are Heated to 395 – 420 degrees

Pipe Ends are joined together to mold into one and 

allowed to cool

Beads are same inside and outside of pipe

What is Electrofusion ?? This technique involves preparing the outside surface of a pipe end, and inserting the Electrofusion fittings onto the pipe.  The inside of the fitting has a copper coil that will heat to specific temperature when connected to  EF processor . The melts from the two components flow together and fuse as the joint cools

Marking the Fusion Zone

Scraping the fusion zone This operation ensures removal of oxide layer, which will increase melt flow 

during the fusion process. It is critical that the oxide layer be removed completely; otherwise it may cause cold welding resulting in leakage.

Insert the Pipe into the Coupler

An assembly, which is stressed, may result in defective joint.  Ensure that both pipes are inserted into the fitting and the two ends are meeting 

each other in the center of the coupler (the cold zone). The maximum allowable gap between the two pipes is to be less than > ½”. If there are stops, push all the way to the stops.

Mis-Alignment- Unacceptable FusionPossible Causes: Inadequate Clamping or

Restraint during fusion.

Mis-Stab- Unacceptable FusionPossible Causes: Failure to mark and monitor

stab depth.

Undersized Pipe, Binding

Cool Time

The Cooling time is a critical step in determining the successful fusion of the EF Coupler to the pipe.

The Cooling Time is indicated by “Cool” on the coupler and is the amount of time required prior to examination, movement, and pressurization of the coupler.

After the Cooling time is finished, you are required to perform a flashlight test, in which the installer views the coupler/pipe interface to check for remaining gaps or wires that can be seen.

Utilize a metal hose clamp or plastic electrical tie to check the coupler/pipe interface to make sure that the tie or claps stops at the first wire.

The EF Fitting can be fused a maximum of 3 times if necessary, after the cooling time.
