Structual
Feature
●
Pressurized
components
adopts
superior
alloy
steel
with
good
strength
and
impact
toughness.
●
Door
seal
of
the
high
pressure
BOP
uses
combined
seal,
which
has
better
seal
from
the
well
pressure.
●
Use
floating
or
integral
gate,
can
seal
safely
and
change
conveniently.
●
Use
buriel-type
oil
passage,
Bearing
hinge
is
separated
from
the
hydraulic
hinge.
●
Hinge
structure
is
simple,
easy
to
dismount
and
mount.
●
Use
big
arc-type
shell
on
both
sides
of
the
chamber,
and
transit
by
arc-type
all
around,
to
reduce
the
peak
stress
of
the
shell
under
pressure.
●
With
compact
structure,
smaller
than
similar
foreign
products.
●
The
internal
shell
of
BOP
resistant
to
low
temperature
can
process
pipeline,
to
make
the
steam
flow
inside
the
BOP,
radiat

Shear
Ram
Shear
ram
can
cut
pipe
the
well,
blindly
close
the
wellhead,
and
also
used
as
blind
ram
when
there
is
no
pipe
in
the
well.
The
installation
of
shear
ram
is
the
same
with
the
original
ram.
●
In
the
normal
condition
used
as
blind
ram,
in
case
of
emergency,
used
as
shear
ram.
●
Shear
damper
can
be
repeatedly
cut
pipe
and
not
damage
the
blade,
The
weared
the
blade
can
be
reused
after
the
repair.
Shenkai
produces
the
shear
ram
with
shear
life
in
more
than
five
times,
Allowed
to
replace
the
sealing
rubber.
●
The
ordinary
ram
blade
is
integrated
with
the
ram
body.
●
The
ram
blade
of
BOP
resistant
to
high
sulfer
is
separated
with
the
ram
body,
which
is
easy
to
change
blade
after
blade
damaged,
and
make
the
ram
body
be
able
to
repeated
use.
●
The
contact
sealing
surface
between
top
seal
of
shear
ram
and
blade
is
large,
which
effectively
reduce
the
pressure
on
the
rubber
sealing
surface,
and
prolong
its
life.
Variable
Ram
Variable
ram
can
be
used
to
seal
different
diameter
of
pipe
string.
Variable
ram
is
composed
of
variable
ram,
top
seal,
variable
front
seal.
The
installation
of
variable
ram
in
the
BOP
is
in
the
same
as
the
common
ram,
don't
need
to
change
any
part
of
the
BOP.
