Operation
Pressure Settings
Charts show pressure settings for various pipe sizes and densities
at different operating temperatures.
Always adjust pressure settings for both rerounder and
straightener systems for changes in temperature. (Higher
temperature = lower setting.)
The LineTamer does not have enough power to properly straighten
and reround pipe at lower temperatures. Operation below 32º F
is not recommended.
IMPORTANT: Charts on machine are range guidelines only for
SDR 11 pipe, at speeds of 50 to 150 ft/min (less than 2 miles
per hour).
Lower speeds will require lower pressure settings.
Thinner wall pipe will require lower pressure settings.
Do not exceed 150 ft/min. pulling speed.

Rerounder Pressure
Select rerounder pressure control valve and set appropriate
pressure value, based on pipe size and material. Refer to
rerounder pressure chart.
NOTICE: Pressure gauge will indicate a lower pressure than your
initial setting if pull is stopped, but will return to original setting
when the pull begins again. If you adjust the setting while the pull
is stopped, the setting will be higher than necessary when the pull
starts again.
Rerounder pressure setting can be maintained during short stops,
but should be reduced during stops of 10 minutes or more.

Straightener Pressure
Select straightener pressure control valve and start pulling pipe slowly
while applying pressure to straightener system. Set appropriate pressure
value, based on pipe size and material. Refer to straightener pressure
chart.
IMPORTANT: Always reduce the pressure on the straightener system
whenever the pipe pull is discontinued. If the pipe pull stops, the
straightener system can kink the pipe when under pressure.
Re-engage when pull is continued, to the initial pressure setting on
straightener gauge.
