Electrofusion Elbow, Tee & Reducer

Electrofusion elbows, tees and reducers, like the electrofusion coupler, have a heating wire inside the body. The pipe ends are cleaned, prepared and pushed into the fitting, and the electrofusion unit passes the right amount of current through the wire so fitting and pipe fuse into one. Because the pipes do not move, the method suits narrow trenches and urban networks.

On gas networks, where weld quality and records matter, electrofusion fittings are the most common choice. These parts are listed to EN 1555-3 for gas and EN 12201-3 for water; state the application in your enquiry.

The 90° elbow and equal tee are listed in 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 225 and 250 mm. The electrofusion reducer joins each diameter to the next smaller one, for example 63 to 50 or 110 to 90 mm.

The electrofusion unit must work up to the largest fitting in the project; the units in our catalogue go up to 160, 250 or 400 mm. In your order give the diameter, the part type, the application (water or gas) and both diameters for a reducer.

The quality of an electrofusion joint depends above all on preparing the pipe surface. The outer layer of the pipe in the fusion zone is scraped, the surface is wiped with a clean cloth and a suitable cleaner, and the insertion depth is marked so the pipe goes into the fitting to the right point.

Pipe and fitting must stay still during fusion and cooling, which is why a holding clamp is used. The unit reads the fusion and cooling times from the fitting's barcode; do not load the joint until the cooling time has passed.
