PRODUCT DESCRIPTION

The Hy-Ram SOU400 Squeeze Off Unit has the facility to enable four simultaneous
squeeze points to be executed. The unique design with dual hydraulic cylinders
provides the hydraulic power to squeeze the pipe to the optimum compression,
(squeeze gap set by pipe stop and guide tube sleeve), then the Top and Bottom Beams
are very simply mechanically locked together.

The Hydraulic Cylinders can then be released from the Bottom Beam and the Piston
Rods extended. The hydraulic cylinders can be easily disconnected from the Beams and
Pipe and carried to the desired position for the next squeeze point. The hydraulic
cylinders can now be connected to a second Beam Set and a second squeeze operation
can be carried out. With four Beam Sets being supplied in the standard kit, by
repeating the procedure above, four simultaneous squeeze points can be achieved.

E. OPERATING INSTRUCTIONS

1.0 PREPARATION

1.1 The Hydraulic Rams should always be transported with the Rams closed. This is

to protect the Piston Rods from being damaged.

1.2 The Rams have to be opened before you can start the operation. Make sure

both the Cylinders are fully open.

1.3 Centrally position Bottom Beam underneath the pipe to be squeezed off at the

desired squeeze off point.

1.4 Identify the pipe diameter and SDR and position pipe stops (C1, C2) on the

bottom beam. (Refer to figure 1.0)

1.5 Load one of the Hydraulic Cylinders onto the bottom beam and insert pin on

Chain into the hole in the rod ends. Lock in position with latch A1 (Refer to
Figure 1.0). You will have to open Latch A1 or A2 to do this then close when
Ram is vertical.

1.6 Load second hydraulic cylinder and lock in position with pin and latch A2.

1.7 Ensure latches (B1, B2) on Top Beam are open. Employing 2 operatives, offer

Top Beam up to the hydraulic cylinders whilst slightly tilting one cylinder through
approximately 15° from vertical position. (Refer to figure 2.0)

1.8 With an operative straddling the pipe, pull the Top Beam upwards, (parallel to

the Bottom Beam). Ensure the bottom of the Hydraulic Cylinder tube is hard up
against top of Top Beam and then secure Top Beam in position using latches
(B1, B2).

1.9 Connect the Hydraulic Hoses from the Power Unit to the Hydraulic Cylinders.

(Refer to figure 3.0)
ALWAYS ENSURE COUPLINGS ARE CLEAN BEFORE CONNECTION.
M1, M2 :Male couplings on hydraulic cylinder
F1, F2 :Female couplings on hydraulic cylinder
M3, M4 :Male couplings on power unit hose
F3, F4 :Female couplings on power unit hose

1.10 Connect either Male Coupling on Power Unit hose (M3, M4) to either

Female Coupling on Hydraulic Cylinder (F1, F2)

1.11 Connect either Female Coupling on Power Unit hose (F3, F4) to either

Male Coupling on Hydraulic Cylinder (M1, M2).

NOTE

The connections are Male/Female screw type quick release couplings. When making
coupling connections, ensure that they are fully ‘made’ (i.e. fully tightened together).

The unit is now ready for connection to the compressor.

SOU400 HANDBOOK 30012013 Page 10

2.0 CONNECTION TO THE COMPRESSOR

POWER UNIT

2.1 Ensure Vent Valve on Power Unit is in ‘Vent’ position.

2.2 Ensure Directional Valve on Power Unit is in ‘neutral’ (centre) position.

2.3 Ensure Compressor has outlet pressure within the range 80-100psi (5.5-6.9 Bar)
If pressure is outside this range: DO NOT USE!

2.4 Ensure Compressor outlet valve(s) are in closed position and start compressor.

2.5 Check outlet pressure is within range 80-100psi (5.5-6.9 Bar).

2.6 Using suitable hose, connect compressor outlet to inlet port on the pressure

regulator on the Power Unit.

WARNING

The pressure regulator is factory preset. DO NOT ATTEMPT TO ADJUST IT!

2.7 Open compressor outlet valve to supply pneumatic pressure to the Power Unit.
The Power Unit will automatically power up and hydraulic fluid will be pumped
around the vent circuit within the power unit recycling fluid internally.

3.0 OPERATION : SQUEEZE OFF

3.1 Turn the vent valve to the closed position, hydraulic power is now available at

the directional valve.

3.2 Turn the directional valve to the ‘Release Position’. This will effectively open the

cylinders and ensure that they are fully extended and synchronised prior to
squeezing off. (Notice that when the Hydraulic Cylinders reach the ends of their
stroke, i.e. fully open or fully closed, the power unit automatically stops).

3.3 Turn the directional control valve to the ‘Squeeze Off Position’. The Top Beam

will begin to travel downwards and start to squeeze the pipe.

WARNING

Ensure the pipe is loaded centrally across the width of the beams.

3.4 If for any reason the squeeze off is required to be stopped return the directional

valve to the central ‘Neutral’ Position.

3.5 Continue to squeeze until the pipe has fully squeezed off and the pipe stops are

sandwiched tight between the Top and Bottom Beams. As stated in 3.2 above,
the Power Unit will automatically stop in the squeezed position (Refer to figure

4.0).

SOU400 HANDBOOK 30012013 Page 11

3.6 Mechanically lock the Top Beam to the Bottom Beam by sliding the latches (B3,

B4) across and tightening the allen screws. The beams are now mechanically
locked together. (Figure 4.0).

3.7 Release cylinder latches (B1, B2) and turn directional valve to release position.

The cylinder will extend leaving the Top and Bottom Beam mechanically locked
together. (Refer to figure 5.0). Allow cylinders to fully extend and Power Unit to
stop.

3.8 Position directional valve in ‘Neutral’ position and vent valve in ‘vent’ position.

The hydraulic hoses can now be disconnected from the cylinders and then the
cylinders can be disassembled from the bottom beam.

3.9 One squeeze off point is now completed. Other squeeze off points can be carried

out by repeating instructions from 1.1 - 3.8, using additional beam sets together
with the original Cylinders/Power Unit.

4.0 OPERATION RELEASE

4.1 To release a squeeze off point, the Hydraulic Cylinders should be re-assembled
onto the Bottom Beam.

4.2 Operate machine in the ‘squeeze off’ position and allow cylinders to close until

they contact the Top Beam and the unit is returned to the position as shown in
figure 4.0. Again the power unit will automatically stop.

4.3 Close latches (B1, B2), locking the Top Beam onto the cylinders. The squeeze off
load is now taken hydraulically and the sliding latches (B3, B4) should be
released.

WARNING

Never attempt to release a squeeze off until the load is taken up on the
hydraulic cylinders.

4.4 The machine should now be operated in the ‘release’ position. The Top Beam will
travel upwards and the squeeze off released.

4.5 Allow the cylinders to fully open and the power unit to automatically stop. The
Top Beam can then be disassembled by releasing latches (B1,B2) and tilting the
cylinder. (Similar to figure 2.0, assembly of Top Beam).

4.6 The squeeze off release is now completed and other squeeze points can be
released in the same manner repeating steps 4.1 - 4.5.

NOTE

Before attempting to disconnect couplings from the cylinder, ensure that the power
unit is run for a short time, in the ‘vent’ position to discharge the pressure in the
hoses. (A Coupling cannot be disconnected whilst pressure is locked in the hoses).
