100% Coverage
(typical arrangement)
Note:
Using this method of assembly,
all studs are tightened simultaneously
in one operation. To allow room for all
tensioners, the protruding studs must
be staggered over each side of the
joint (see above).

Note:
In stage one,
50 % of the studs are
tensioned, In stage
two, the remaining
50% of the studs are
tensioned.
Note:
This method of assembly
is often used where studs can be
tensioned from only one side of the
joint due to an access restriction on
the opposite side. The studs must
be assembled with the protrusions
on the same side of the joint (see
below).

6.3 Tensioner Arrangements (typical)
Hydraulic tensioners can be mounted on either
one or both sides of the joint, depending on
available clearance and work room. Whenever
possible, all studs on the joint should be
tensioned at the same time. Typical examples of
100% and 50% tensioner coverage are shown
in Figure 6. Contact Enerpac for additional
information regarding tensioner arrangements
of less than 50% coverage.
Note:
For less than 100% coverage, divide the
quantity of tensioners available into the quantity
of studs in the joint. This will determine the stud
locations to be tightened during each pass. For
example, if 18 tensioners are available for a 36
bolt joint, then every second stud will contain a
tensioner (50% coverage). If 12 tensioners are
available, then every third stud will contain a
tensioner (33% coverage).
