5.1 Initial Setup and Inspection
The Secure Grip Tools spread flange joints
by engaging collets into the bolt-holes.
They can easily spread flange joints with
zero access gap, which traditional wedge-
type flange spreaders cannot spread.
The collets are suited to the sizes of the
bolt-holes and should be selected prior
to commencing work by following the
instructions in this section.
Replacement collets or different collets to
suit different bolt-hole sizes are available
from a local Equalizer distributor.
5.2 Collet Selection
It is important that the
correct size of collet is used. An undersized
collet could allow the collet holder to pull
through its bore. An oversized collet has
the potential to become jammed in the bolt-
hole.
The Secure Grip tools have a range of
collets which are applicable to the following
bolts and flange bolt-hole diameters shown
in the table below.
WARNING

IM_SGM_07 11
5.3 Bolt Hole Measurement
To ensure a true measurement is taken,
hold the vernier calliper:
• Square to the flange face,
• In the middle of the bolt-hole.
It is important that the vernier calliper is held
in the middle of the bolt-hole, and not held
at an angle to the flange face, nor used on a
bolt-hole which is worn, damaged or
distorted, as these actions may result in the
selection of an incorrect size of collet.
To confirm that the bolt-hole is round, take
two separate measurements with the vernier
calliper turned through 90° between
measurements.
To read the measurement from the vernier
calliper, scan along the desired scale from
left to right. In this example, the major figure
is 60mm, this is added to the minor figure
of 8 mm (indicated by where the vernier
scale aligns with the main scale), giving a
total measurement of 68mm.
With a bolt-hole size of 68mm, the operator
can determine which collet and tool is
appropriate to this flange by referring to
the table. For example: 68mm falls within
the 63mm minimum and 69mm maximum
bolt-hole sizes.
Therefore, collet identification is M64 / 2½"
If the measurement contains fractions of a
millimetre the method of reading the vernier
calliper is slightly different. In this example,
the major figure is 40mm (read in the same
way as previously described). The minor
figure is 7mm (read to the left of the zero).
The fraction is 0.5mm (read from where the
vernier scale lines up with the main scale).
This gives a total measurement of 47.5mm.
Major
Figure Minor
Figure

12 IM_SGM_07
Each tool in the Secure Grip range comes
with the appropriate sizes of Collets for
that tool. If the Collet labelling is worn or
missing, then the Collet can be measured
to ensure that the correct size is selected.
An accurate measurement can only be
obtained with the Collet mounted on the
Collet Holder. To do this:
• Remove the Collet Head Assembly from
the tool and disassemble (see Section
5.4 for details)
• Slide the Collet over the Collet Holder
• Measure the centre section of the Collet
with the vernier calliper
• Identify the Collet using the chart below
and select the correct size for the flange.
The Secure Grip collets are
consumable items. The lifespan of a collet
will vary depending on the flange materials
with which it is used. To increase the lifespan
of the collets it is recommended that they
are flipped through 180° on the collet holder,
this will produce more even wear across the
four ridges on the outer profile of the collet.
See Section 5.4 for details on collet removal
and replacement.

5.4 Collet Replacement
Once the correct collet has been selected it
may be necessary to change the collet on
the SG4TM, SG6TM, or SG11TM tool:
Place the tool on its side on a work bench or
flat surface. Unscrew and remove the collet
nut.
Pull the Collet Spring Plunger Ring to
release and remove the collet head
assembly.
Remove the Drive Cone and Collet from the
Collet Holder. Replace the Collet with the
applicable size for the flange joint as
selected in Section 5.2.
Repeat the operation for the opposite Collet
Leg Sub-assembly.
Reverse the procedure to re-assemble the
tool. Care should be taken to ensure the slot
in the Collet holder is aligned with the collet
plunger.
5.5 Collet Leg Sub-Assembly -
Installation
The Collet Leg Sub-assemblies, as used in
tools SG4TM, SG6TM, SG11TM; should be
the first parts of the tool fitted to the flange
joint.
The Collets from each assembly should be
installed into the bolt-hole of the flanges on
either side of the joint to be spread. Care
should be taken to ensure that the Collets
are engaged in the correct position.

14 IM_SGM_07
If a spacer, blind or valve is installed
between the flanges, care should be taken
to ensure that the Collet or Collet Holder do
not extend beyond the flange bolt hole.
5.6 Tool Installation and Operation
Once the correct Collet has been
selected and mounted, tool operation can
commence.
The two halves of the mechanical Secure
Grip are inserted into opposing flange bolt-
holes.
Both drive nuts are tightened, locking the
tool into the flange bolt-holes.
The cantilever followed by the actuator are
swung and locked into position.
Drive Nut
Drive Nut
Cantilever
Actuator
Cantilever
Actuator
The actuator is tensioned, spreading the
flange to the maximum load capacity or
maximum spreading distance of the tool.
Before attaching the tool
ensure at least two flange bolts remain in
place 180 degrees apart with nuts loosened
sufficiently enough for flange work to be
carried out. These bolts will reduce lateral
flange movement during flange spreading.
Mechanical Tool Operation
The mechanical Secure Grip tools use
mechanical torque to advance the actuator
and spread the tool. The torque is applied
using the supplied torque wrench, enabling
accurate control of the force applied.
Torque Wrench Usage
Holding the Torque Wrench in one hand,
unlock the knurled handle by turning the
locking knob anti-clockwise.
Select the torque setting by turning the
knurled handle until the required torque
value is indicated.
WARNING

IM_SGM_07 15
For example, to set the Torque Wrench to
46N·m: turn the knurled handle until the 0
on the fine scale aligns with 40N·m on base
scale; now turn slightly further until the 6 on
the fine scale aligns with the central line.
Setting an imperial torque [in ft·lb] is done in
exactly the same way.
Lock the handle by turning the locking knob
clockwise.
Install the supplied socket onto the Torque
Wrench and attach to the tool.
Slowly and smoothly pull the handle,
gradually applying more force until you feel
or hear the Torque Wrench click, indicating
that the selected torque has been achieved.
Do not continue to apply force after the
Torque Wrench has clicked. Special care
should be taken when using low torque
settings.
Do not attempt to turn the
grip while it is locked. Do not turn the grip
more than one turn below the lowest scale
reading or above the highest scale reading.
CAUTION
Torque Wrench Care
Prior to storing the Torque Wrench, and
between use, leave the Torque Wrench with
its lowest torque setting selected.
To clean the Torque Wrench, wipe gently
with a damp cloth. Avoid using any detergent
or solvent as this may detrimentally affect
the factory-fitted internal lubrication of the
mechanism.
Measure the thickness of the flange using
the vernier calliper provided. Adjust the
depth gauge to one half of the flange total
length and lock the calliper in position by
tightening the locking screw.
Select a suitable bolt-hole in which to attach
the tool.
Insert the depth gauge part of the vernier
calliper into the bolt-hole keeping the base
of the calliper flush with the bolting face of
the flange.

Insert the collet on the cantilever half of the
tool into the opposite end of the same bolt-
hole until it touches the end of the depth
gauge (so that the Collet is fully through one
flange but not entering the other).
Set the torque wrench to 30N·m [22ft·lb]
and tighten the drive nut until the torque
wrench clicks.
The cantilever half of the tool will now have
a secure hold in the bolt-hole.
Insert the Collet on the actuator half of the
tool into the bolt-hole until it touches the
collet on the cantilever half of the tool.
Tighten the drive nut with the torque wrench
pre-set to 30N·m [22ft·lb] until it clicks. The
actuator half of the tool will now have a

the cantilever fully locked into position may
result in personnel injury and damage to the
tool.
Ensure the actuator bolt is fully unscrewed,
then swing the actuator down into position.
Tighten the actuator bolt until the lugs on
the actuator union engage in the hooks on
the open legs.

Select the bolt-hole 180° opposite the tool
that has just been attached and repeat the
above steps for the second tool.
If more than two tools are
being used they should be attached at an
equal spacing around the flange joint.
With the torque wrench set at 30 N·m
[22 ft·lb], tighten the actuator bolt on one
tool until the torque wrench clicks and then
torque the actuator bolt on the other tool.
Continue tensioning the actuator bolts until
the flange spreads or the torque wrench
clicks. Care should be taken to ensure the
actuator bolts maintain an equal tension on
both tools.
CAUTION
When the torque wrench clicks, stop and
increase the torque wrench setting by
10N·m [6.5ft·lb]. Continue to tension both
tools evenly until the flange spreads or the
torque wrench clicks.
If the torque wrench clicks, continue
increasing the torque wrench setting in
10 N·m [6.5 ft·lb] increments until the
maximum for the tool has been reached
(see table below).
If a greater spreading force
is required then further tools can be added
around the flange joint.
Overloading the tool will
cause tool failure which may result in
personal injury.

Continue spreading the flange until the
access gap required has been achieved or
until the maximum tool travel has been
reached.
The Secure Grip mechanical
tools are fitted with an internal mechanical
stop which limits the travel. Forcing the tool
to travel further will result in tool failure.

Once the flange has been separated
and prior to any maintenance work, the
safety blocks must be inserted between
the flanges. These are held in position by
removing two of the flange bolts that are
reinserted with the safety block positioned
in-between the flange faces.

WARNING
Do not allow fingers, hands
or other body parts to come into contact
with the flange or tools during operations.
Never place fingers, hands or other body
parts into the flange gap.
Following any maintenance works and prior
to closing the flange joint, the safety blocks
must be removed.
To reduce the load on each tool rotate the
actuator bolt one full rotation. Repeat this
on both tools in turn until the tools have no
load on them and the joint is closed.
The tools can then be removed from the
flange by reversing the installation
procedure.
