Butt Fusion Procedure
3 - 5
Remove Facer
Move the carriage control valve to the open carriage position and
open the carriage.
Release the trigger lock, and move the facer out.
Remove chips from pipe ends.
Do not touch faced pipe ends.
Inspect both pipe ends for complete face off. If the face off is
incomplete, return to
Loading Pipe into Machine
.
Move the carriage to the left until ends of pipe butt together.
Check pipe joint for proper alignment.
Do not use finger to check for hi/lo
(misalignment). The unit is under pressure, and
slippage could result in crushed fingers. Always
keep hands clear of the jaw area.
If pipe is not lined up, tighten the high side jaw to bring into
alignment.
IMPORTANT:
Always tighten the side that is higher, never loosen
the low side.
When the pipe is properly aligned tighten outside clamps to insure
against slippage (4 Jaw units only).
Ensure there is no unacceptable gap between the pipe ends.
If there is an unacceptable gap, return to
Loading Pipe into
Machine
.
NOTICE:
When clamping, do not over-tighten the clamp knobs
because machine damage can result. Check to see if there is
space between the upper and lower jaws. If the two jaws are
touching, do not continue to tighten.
Bring the pipe ends together under fusion pressure to check for
slippage. If slippage occurs, return to
Loading Pipe into Machine
.
