Pneumatic rubber fenders have a long and successful history of protecting vessels in mooring operations. They are ideal for permanent and semi-permanent port applications and for offshore ship-to-ship transfers. Tough and resilient, rubber dock fenders are fast and easy to deploy, maintaining large clearances between the hull and the jetty or other vessel.
This serves to minimise damage potential during mooring. Critical properties of rubber fenders are energy absorption, hull pressure and reaction force. In both cases, Xincheng Marine Systems products score very highly, with low reaction force and low hull pressure.This means the fender absorbs significant energy, reducing the forces on both the vessel hull and jetty structures.
Construction
of
pneumatic
fender
Pneumatic
Fenders
are
constructed
of
three
vulcanized
layers
each
providing
an
important
function
in
the
construction
and
lifespan
of
the
fender.
The
three
layers
are
(1) the inner rubber layer
The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.
(2) the tyre-cord layers of reinforcement
Synthetic tyre-cord layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and wear during bending, compression and stretching. The same compound isolates each thread within the layer.This greatly improves the ability of the fender to hold pressure, fatigue resistance and endurance life. Other reinforcing layer materials such as canvas have wear points that significantly reduce the life off the fender.
(3) the outer rubber layer.
The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.

ADVANTAGES
1),
safe
for
excess
load
marine
depend
on
the
ball
The
reaction
force
of
a
floating
pneumatic
fender
does
not
increase
sharply
even
under
excess
load.
Therefore,
these
fenders
perform
extremely
well
under
such
condation
and
as
a
result,
protect
ships
and
mooring
facilities.
2),
No
deterration
or
variation
in
performance
Because
pneumatic
fenders
utilise
the
compressive
elasticity
of
air,
performance
deteriation
due
to
fatigue
is
completely
absent.
The
performance
of
these
fenders
remain
unchanged
at
extremely
low
temperatures,
even
below
-
50'C.
3),
safety
realiability
Xincheng
pneumatic
rubber
fender
are
constructed
using
several
layers
of
strong
tyre
cord
are
therefore
extremely
resistant
to
pressure
and
cutting,
and
are
therefore
extremely
resistant
to
pressure
and
cutting.
The
larger
size
(
2.5m
dia
upward
)
are
fitted
with
safety
valve
to
prevent
accident
in
the
event
of
over
copressiom.
4),
construction
The
fender
body
is
constructed
of
an
inner
rubber
layer,
reinforcing
cord
layers
and
an
outer
rubber
layer.
All
three
layers
are
bonded
together
by
a
combination
of
heat
and
pressure
over
a
period
of
time
in
a
vulcanising
oven.
Once
completed,
the
fenders
are
pressure
tested
before
relase.
To
provide
maximum
strength
and
safety,
the
out
skin
of
submarine
fender
is
thicker
than
a
normal
surface
fender.
The
outer
skin
rubber
compound
is
desinged
and
manufactured
to
be
able
to
withstand
both
strenuous
use
and
adverse
weather.
Condations
whilst
protecting
the
cord
layers
and
inner
rubber
the
cord
layers
are
corranged
at
optimum
angles
designed
to
be
completely
airtight.
5),
Simple
and
low
cost
installation
The
weight
of
the
fenders
is
supported
by
the
water
on
which
it
floats,
therefore,
the
fender
can
be
morred
simply
by
means
of
a
guy
rope
or
chain
at
minimal
cost
it
can
be
removed
easily
to
another
quay
or
jetty
when
not
use
or
transfeered
to
alternative
mooring
points
as
required
6),
chain
and
tyre
net
Almost
floating
fenders
are
protected
by
a
chain
and
tyre
net.
The
purpose
of
the
chain
and
tyre
net
is
to
protec
the
fender
body
from
damage
by
sharp
objets
or
protrusions
such
as
rough
faced
quay
walls,
to
distribute
sheer
forces
along
the
length
of
the
chain
net
and
to
prevent
the
fender
body
from
having
to
absorb
them.
