3.0 PRODUCT DESCRIPTION
The Enerpac wedge spreader FSM-8 is a manual
operated tool.
The Enerpac FSH-14 is a hydraulic operated tool.
Both wedge sp
readers use the integrated wedge
concept. They are used to spread flanges in order to
create space for cleaning and repairing flange
surfaces and gasket replacement.
The FSM-8 is actuated by a 22 mm ratchet spanner.
The FSH-14 is actuated by an Enerpac RC-102
single acting cylinder. The FSH-14 must be powered
by an Enerpac hand pump.
3.1 Applications
Wedge spreaders can be used for: pipe and flange
repair, removing of elbows, couplers, gasket and
metal seals replacement, maintenance/ replacement
of valve and control equipment.
4.0 OPERATING INSTRUCTIONS
It is recommended that two wedges be used in
tandem. This will give an even spread to the joint.
The wedges should be set at 180˚ apart
(see fig. 1) .
The wedge should be used only if the full step area is
located into the gap, and the object requiring
spreading is in contact with the heel of the next step
(see fig. 2) .
IMPORTANT: Ensure wedge is fully located on the
step selected to spread (see fig. 2 and 3) .
Minimum hold should be 15 mm.
IMPORTANT: The safety block (see fig. 4) may be
inserted into the joint and the pressure released onto
the block.
IMPORTANT: A fresh hold on a new step can then
be chosen to open the joint further if required.
IMPORTANT: The operator must ensure that the
wedge and the 4 slide pins are lubricated each and
every time the equipment is used. This will give
maximum efficiency and prolong the working life of
the wedge.
WARNING: Never place fingers in a joint held by
activated wedge unless a safety block is located into
the joint.
CAUTION: The handle of the wedge is there to stop
operators holding spread plates as the wedge is
retracted. This will stop fingers becoming jammed
between plates.
CAUTION: Never hammer or force wedge to access
gap.
CAUTION: Don't operate the equipment without
lubricating the wedge and the 4 slide pins.
5.0 USE OF STEPPED BLOCKS (FSB-1)
The maximum opening of the wedge spreaders can
be increased from 61 to 81 mm when used in
combination with the optional FSB-1 stepped blocks
(see fig. 5 and 6) .
The FSB-1 give more access to replace ring joints,
metal seals and cleaning of flange surfaces. The use
of stepped blocks reduce the amount of penetration
of the wedge point into the joint.
