Fusion


1 Mark the pipe
Mark the pipe for depth of penetration into the heater bush and fitting (see table). The mark must remain visible under heating and joining.

2 Heat pipe & fitting
Push the pipe and the fitting into the heating tools. Once pipe and fitting are hot (after the correct time), pull out pipe and fitting very slowly.

3 Joint pipe & fitting
Joint the pipe & the fitting and push the pipe until it reaches the mark (that has to stay outside).
During the jointing time the welded part of pipe and fitting must remain fix, without any rotation.
During the cooling time, the welded part of pipe and fitting can be adjusted until cold.

4 Fusion inspection
Fusion inspection. The outer fusion seam must be inspected. The seam must be present all around the pipe.
