Socket Fusion Installation
Fusion
1. Mark the pipe
Mark the insertion depth on the pipe for (see table).
The mark must remain visible under heating and jointing.
2. Heat pipe & fitting
Push the pipe and the fitting straight into the heating
bushes. Pull out the pipe and fitting slowly and without
twisting once the heating time has elapsed.
3. Joint pipe & fitting
Push the pipe into the fitting so that the welding beads of
pipe and fitting touch together. During the jointing time,
small adjustment in angle and alignment can be made.
During the cooling time, any stress on the joint must be
avoided.
4. Fusion inspection
The outer fusion bead must be inspected. A double bead
must be uninterrupted all around the pipe circumference.
