7. Insert a length of pipe that is the correct size
and thickness onto the lower roll. Ensure that
the pipe end contacts the lower-roll backstop
flange completely.
8.
While manually supporting the pipe, depress
and hold down the safety foot switch. The upper
roll will advance and contact the pipe. Remove
hands from the pipe.
NOTICE
• Occasionally during grooving, the groove
diameter stop may move up and down
slightly, making contact and then
breaking contact with the hydraulic
cylinder. This is normal for pipe that has
a noticeable weld seam or hard spot.
9.
As grooving continues, the groove diameter
stop will move down and contact the hydraulic
cylinder. This contact activates the dwell timer,
which allows the pipe to rotate one to three more
revolutions to ensure groove completion (refer to
the “Dwell Control Adjustment” section).
a. The upper roll will retract automatically
and will release the pipe.
b. Release the safety foot switch, and
withdraw foot from the switch.
10.
Inspect the groove/pipe end to ensure they
are within Victaulic specifications.
11. If roll grooving will not be performed for
an extended time period, turn off the hydraulic
system by pushing the “EMERGENCY STOP”
button on the control panel.
NOTICE
• The groove diameter shall be within
specification for the diameter and wall
thickness of pipe. The groove diameter
should be checked and adjusted, as
necessary, to ensure grooves remain
within specification.
