are set correctly when the correct end face is pointing downwards
and positioned to contact the bottom bar when this is re-fitted.
5. Position the mainframe over the pipe to be squeezed and slide
the bottom bar into the loops of the mainframe beneath the pipe,
position the pipe centrally between the squeeze bar and bottom bar.
6. Close the Hydraulic Jack control valve by screwing clockwise using
the jack handle.
7. Fit the jack handle into the collar of the pump on the jack.
Commence pumping the jack to apply the squeeze pressure.
8. Continue the pumping action until the squeeze bar has fully closed
the pipe, and the limit stop plates prevent further compression.
9. Screw down both check screws until they are in contact with the
upper edge of the squeeze bar. This will prevent any loss of squeeze
pressure in the event of hydraulic pressure leakage in the jack.
Removal After Squeeze Off
On completion of the squeeze off operation, remove the tool as follows:
1. Unscrew the check screws until their threads are clear of the safety
check screws threaded blocks. (If it is difficult to release the check
screws, pump the jack handle 2 or 3 times to replace any loss of
hydraulic pressure).
2. Gently release the hydraulic jack pressure by unscrewing the
pressure control valve anti clockwise with the jack handle. This may
require carrying out in controlled stages to prevent flow surges and
excessive pressure drops in the pipe-work as the system fills up.
3. Allow the jack and squeeze bar to retract fully in the main frame
under the force of the return springs, remove the bottom bar and lift
the main frame clear of the pipe.
4. Allow the section of squeezed pipe to reform to its original shape,
this may take several hours.
5. A selection of post squeeze-off re-rounding tools are available to aid
the pipe in regaining its original shape, vistit
