What
is
the
HON
COCON
13
The
HON
Cocon
13
is
a
complete
self
‐
contained
underground
gas
regulating
station
for
the
reduction
of
gas
pressure.
The
station
can
be
completely
buried
or
installed
above
ground
in
an
area
much
smaller
than
a
conventional
regulating
station.
The
station
ensures
reliable
gas
supply
at
a
constant
pressure
independent
of
the
gas
consumption.
The
station
having
all
essential
elements
of
a
conventional
pressure
reduction
station
is
designed
for
use
on
gas
distribution
and
industrial
applications.
Only
a
very
restricted
area
is
required
for
installing
the
station.
The
working
elements
are
contained
in
a
removable
cartridge
retained
by
a
simple
closing
construction.
All
being
housed
in
a
steel
body
that
is
installed
underground
into
the
gas
main.
Above
ground
is
a
vent
stack,
which
contains
vent
pipes
for
atmospheric
reference
and
the
relief
valve.
The
HON
Cocon
is
supplied
pre
‐
assembled
into
a
skid
package,
which
considerably
reduces
the
on
‐
site
installation
time.
The
station
is
made
of
steel,
aluminum,
bronze
and
synthetics.
The
station
can
be
produced
in
other
materials
upon
request.

Construction
Remark:
For
the
location
of
the
parts
of
the
gas
pressure
reducing
station,
mentioned
in
the
text,
we
refer
to
illustration
2.4.1.
The
short
numbers
between
the
brackets,
which
are
mentioned
in
the
text,
are
position
numbers
of
the
parts
in
illustration
2.1.
The
top
of
the
station
is
located
a
few
centimeters
above
or
at
ground
level.
Depending
on
the
composition
of
the
soil,
a
concrete
foundation
(plate)
under
the
station
may
be
needed.
The
gas
regulating
station
HON
COCON
13
consists
of
two
parts:
‐
The
body.
‐
The
gas
regulating
and
safety
unit.
(Cartridge)
Remark:
The
"gas
regulating
and
safety
unit"
will
be
referred
to
as
the
cartridge
in
the
rest
of
the
manual.
