Since
each
of
these
penstocks
is
designed
to
comply
with
the
operating
conditions
of
each
installation,
there
are
several
options
to
install
the
FL
penstock.
The
most
notable
are
the
two
most
common
options:
one
is
bolted
to
an
existing
flange
and
the
other
is
mounted
on
a
wall
and
secured
with
anchors.
Each
of
these
options
is
described
in
detail
below.
To
mount
the
penstock
bolted
to
a
flange
(fig.
5),
these
steps
should
be
followed:
‐
Position
the
penstock
supported
on
the
flange
of
the
installation,
checking
that
the
boreholes
coincide
with
the
penstock
body
boreholes.
‐
After
ensuring
that
the
borehole
coincides,
remove
the
penstock
from
the
flange.
‐
Clean
the
face
of
the
flange
where
the
penstock
is
to
be
mounted.
‐
Position
a
sealtight
joint
on
the
flange,
in
order
to
ensure
there
are
no
leakages
to
the
outside
where
the
flange
and
the
penstock
come
together.
The
seal
to
be
installed
will
be
selected
in
line
with
the
working
conditions
inside
the
line
(temperature,
pressure,
type
of
fluid,
etc).
‐
Check
that
the
penstock,
the
inside
of
the
body
and,
above
all,
the
sealing
area
are
clean.
‐
Clean
the
face
of
the
body
supported
on
the
flange.
‐
Position
the
penstock
supported
on
the
flange.
‐
Position
the
penstock
so
the
turning
point
of
the
flap
(body
lugs)
remains
in
the
upper
part
of
the
installation.
‐
Ensure
that
the
sealtight
joint
between
the
flange
and
the
penstock
is
correctly
positioned.
‐
After
correctly
positioning
both
the
sealtight
joint
and
the
penstock,
fasten
the
joining
bolts.
These
bolts
and
nuts
must
be
suitable
for
the
operating
conditions.
‐
Once
all
the
bolts
are
in
place,
tighten
crosswise
with
a
low
initial
torque.
‐
Finally,
complete
the
final
torque
in
accordance
with
the
applicable
standard.
‐
After
carrying
out
all
these
steps
and
before
finishing
the
assembly
process,
check
that
the
flap
swivels
without
any
difficulty
on
the
turning
point.
